STEP 3: Structure of Endocrine System (45 minutes) |Activity: Small Group Discussion ( 30 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | | | |What are the glands which form the endocrine system? | | | |ALLOW students to discuss for 15 minutes | | | |ALLOW few groups to present and the rest to add points not mentioned | | | |CLARIFY and SUMMARIZE by using the contents below | • The endocrine system is the combination of endocrine glands which secrete hormones • The endocrine glands are: o Pituitary gland o Thyroid gland o Parathyroid gland o Adrenal gland o Pancreas o Ovaries o Testes Pituitary gland • It hangs from the hypothalamus and is enclosed by the sphenoid bone • It is divided into posterior pituitary gland and anterior pituitary gland o Posterior pituitary gland. ▪ The two hormones of the posterior pituitary gland are produced by the hypothalamus and stored in the posterior pituitary gland until needed ▪ These hormones are anti-diuretic hormone (vasopressin) and oxytocin and both are peptides. ▪ Antidiuretic hormone increases the reabsorption of water by kidney tubules, which decreases the amount of urine formed. ▪ The water is reabsorbed into the blood, so as urinary output is decreased, blood volume is increased, which helps maintain normal blood pressure ▪ Oxytocin stimulates contraction of the uterus at the end of pregnancy and stimulates release of milk from the mammary glands. o Anterior pituitary gland ▪ The hormones produced are regulated by releasing hormone from the hypothalamus. ▪ The hormones produced are growth hormones (somatotropin), thyroid stimulating hormone, adrenocorticotropic hormone, prolactin, follicle stimulating hormone and luteinizing hormone. ▪ Growth hormones promote growth as increases amino acids transport and protein synthesis. ▪ Thyroid stimulating hormone stimulates the normal growth of the thyroid and the secretion of thyroxine (T4) and triiodothyronine (T3). ▪ Adrenocorticotropic hormone (ACTH) stimulates the secretion of cortisol and other hormones by the adrenal cortex. ▪ Secretion of ACTH is increased by corticotropin-releasing hormone (CRH) from the hypothalamus. ▪ Prolactin is responsible for lactation. More precisely, prolactin initiates and maintains milk production by the mammary glands. ▪ Follicle stimulating hormone stimulates the growth of ovarian follicles; that is, it initiates egg development in cycles of approximately28 days. ▪ Luteinizing hormone is responsible for ovulation, the release of a mature ovum from an ovarian follicle. Thyroid gland • The thyroid gland is located on the front and sides of the trachea just below the larynx • The structural units of the thyroid gland are thyroid follicles, which produce thyroxine (T4) and triiodothyronine(T3) and iodine is necessary foe production of these hormones o Thyroxine and T3 ▪ Thyroxine (T4) and T3 have the same functions: regulation of energy production and protein synthesis, which contribute to growth of the body and to normal body functioning throughout life. ▪ Thyroxine and T3 increase cell respiration of all food types (carbohydrates, fats, and excess amino acids) and thereby increase energy and heat production. o Calcitonin ▪ Decreases the reabsorption of calcium and phosphate from the bones to the blood, thereby lowering blood levels of these minerals. ▪ This function of calcitonin helps maintain normal blood levels of calcium and phosphate and also helps maintain a stable, strong bone matrix. Parathyroid gland • They produce a hormone called parathyroid hormone. • Parathyroid hormone is an antagonist of calcitonin • It increases the reabsorption of calcium and phosphate from bones to the blood, thereby raising their blood levels. And also increase their absorption from

Disorders of the thyroxine • Goiter o It is caused by dietary deficiency of iodine o In an attempt to produce more thyroxine, the thyroid cells become enlarged, and hence the thyroid gland enlarges and becomes visible on the front of the neck. • Cretinism o It is a condition of hypo secretion of thyroxine in new born o It retards both physical and mental development. • Myxedema o It is a condition of hypo secretion of thyroxine in adults o This decreases metabolic rate and hence general body weakness • Grave’s disease o This is autoimmune disease which result to hypersecretion of thyroxine hormone Diabetes Mellitus • There are two types of diabetes mellitus: o Type 1 is called insulin-dependent diabetes and its onset is usually in childhood (juvenile onset). ▪ Is characterized by destruction of the beta cells of the islets of Langerhans and a complete lack of insulin o Type 2 is called non–insulin-dependent diabetes, and its onset is usually later in life (maturity onset). ▪ Insulin is produced but cannot exert its effects on cells because of a loss of insulin receptors on cell membranes. ▪ Risk factors include a family history of diabetes and being overweight. Control may not require insulin, but rather medications that enable insulin to react with the remaining membrane receptors. Disorders of the adrenal cortex • Addison’s disease o Itis a result of hypo secretion of the adrenal cortical hormones. o Atrophy of the adrenal cortex decreases both cortisol and aldosterone secretion. o Deficiency of cortisol is characterized by hypoglycaemia, decreased gluconeogenesis, and depletion of glycogen in the liver. ▪ Consequences are muscle weakness and the inability to resist physiological stress. o Aldosterone deficiency leads to retention of potassium and excretion of sodium and water in urine. ▪ The result is severe dehydration, low blood volume, and low blood pressure. • Cushing’s syndrome o Itis a result of hypersecretion of the adrenal cortex, primarily cortisol. o The cause may be a pituitary tumour that increases ACTH secretion or a tumour of the adrenal cortex itself. o Excessive cortisol promotes fat deposition in the trunk of the body, while the extremities remain thin. o The skin becomes thin and fragile, and healing after injury is slow.

Autonomic Nervous System • The part of the nervous system that regulates the involuntary activity of the heart, intestines, and glands, including digestion, respiration, perspiration, metabolism, and blood-pressure modulation. Somatic Nervous System • The part of the peripheral nervous system that transmits signals from the central nervous system to skeletal muscle and from receptors of external stimuli, thereby mediating sight, hearing and touch. Nerves • Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Components of the nervous system: • The Central Nervous System o Brain o Spinal cord • Peripheral Nervous system is divided into: o Autonomic nervous system o Peripheral nervous system STEP 3: Nerve Tissue (20 minutes) |Activity: Small Group Discussion ( 30 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | |What are the parts of neuron? | | | |ALLOW students to discuss for 15 minutes | | | |ALLOW few groups to present and the rest to add points not mentioned | | | |CLARIFY and SUMMARIZE by using the contents below | • Nerve tissue is made up of nerve cells called neurons or nerve fibers • All neurons have the same physical parts. o The cell body contains the nucleus and is essential for the continued life of the neuron. o Dendrites are processes (extensions) that transmit impulses toward the cell body. o The one axon of a neuron transmits impulses away from the cell body. o It is the cell membrane of the dendrites, cell body, and axon that carries the electrical nerve impulse. o Axons and dendrites are collectively called Schwann cells in the peripheral nervous system and are covered by a membrane called myelin sheath. o Node of Ranvier is the spaces between adjacent Schwann cells or segments of myelin sheath. o Neurolema are the nuclei and cytoplasm of Schwann cells. • Synapse. o It is the small gap or space between the axon of one neuron and the dendrites/cell body of the next neuron. o The synaptic knob of presynaptic axon contains chemical neurotransmitters that are released to the synapse on the arrival of an impulse. o Synapses ensure one way impulse transmission o The neurotransmitter diffuses across the synapse, combines with specific receptor sites on the cell membrane of the postsynaptic neuron, and there generates an electrical impulse that is, in turn, carried by this neuron’s axon to the next synapse. o Example of neurotransmitter is acetylcholine found at the neuromuscular junction. • Types of neurons o Neurons are classified in to three groups which are : ▪ sensory (afferent) neuron, ▪ motor (efferent) neuron ▪ Interneuron. o Sensory neurons ▪ Carry impulses from receptors to the central nervous system. ▪ Receptors detect external or internal changes and send the information to the CNS in the form of impulses by way of the afferent neurons. ▪ The central nervous system interprets these impulses as a sensation. o Motor neurons ▪ Carry impulses from the central nervous system to effectors. ▪ The two types of effectors are muscles and glands. ▪ In response to impulses, muscles contract or relax and glands secrete. o Interneurons ▪ They are found entirely within the central nervous system. ▪ They are arranged so as to carry only sensory or motor impulses, or to integrate these functions. ▪ Some interneurons in the brain are concerned with

This anatomic arrangement has physiological importance. • Parasympathetic division o The parasympathetic division dominates in relaxed (non-stress) situations to promote normal functioning of several organ systems. o In the parasympathetic division, one preganglionic neuron synapses with just a few postganglionic neurons to only one effector. With this anatomic arrangement, much localized (one organ) responses are possible. • In autonomic pathways there are two synapses: one between preganglionic and postganglionic neurons, and the second between postganglionic neurons and visceral effectors. o Acetylcholine is the transmitter released by all preganglionic neurons, both sympathetic and parasympathetic and is inactivated by cholinesterase in postganglionic neurons. o Parasympathetic postganglionic neurons all release acetylcholine at the synapses with their visceral effectors. o Most sympathetic postganglionic neurons release the transmitter norepinephrine at the synapses with the effector cells. o Norepinephrine is inactivated by either catechol-Methyltransferase (COMT) or monoamine oxidase (MAO), or it may be removed from the synapse by reuptake.

Session 38: Cardinal Signs of Inflammation 279 Background There is currently an ever increasing demand for pharmaceutical personnel in Tanzania. This is due to expanding investment in public and private pharmaceutical sector. Shortage of trained pharmaceutical human resource contributes to poor quality of pharmaceutical services and low access to medicines in the country (GIZ, 2012). Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs) worked together to address the shortage of human resource for pharmacy by designing a project named “Supporting Training Institutions for Improved Pharmaceutical Services in Tanzania” in order to improve quality and capacity of PTIs in training, particularly of lower cadre pharmaceutical personnel. The Pharmacy Council formed a Steering committee that conducted a stakeholder’s workshop from18th to 22ndAugust 2014 in Morogoro to initiate the implementation of the project. Key activities in the implementation of this project included carrying out situational analysis, curriculum review and harmonization, development of training manual/facilitators guide, development of assessment plan, training of trainers and supportive supervision. After the curricula were reviewed and harmonized, the process of developing standardised training materials was started in August 2015 through Writer’s Workshop (WW) approach. The approach included two workshops (of two weeks each) for developing draft documents and a one-week workshop for reviewing, editing and formatting the sessions of the modules. The goals of Writers Workshops were to build capacity of tutors in the development of training materials and to develop high-quality, standardized teaching materials. The training package for pharmacy cadres includes a Facilitator Guide, Assessment plan and Practicum. There are 12 modules for NTA level 4 making 12 Facilitator guides and one Practicum guide. Acknowledgement The development of standardized training materials of a competence-based curriculum for pharmaceutical sciences has been accomplished through involvement of different stakeholders. Special thanks go to the Pharmacy Council for spearheading the harmonization of training materials in the pharmacy after noticing that training institutions in Tanzania were using different curricula and train their students differently. I would also like to extend my gratitude to St. Luke Foundation (SLF)/Kilimanjaro School of Pharmacy –Moshi for their tireless efforts to mobilize funds from development partners. Special thanks to John Snow Inc (JSI), Deutsche GesellschaftFür Internationale Zusammenarbeit (Giz), Merck Kgaa, BoehringerIngelheimGmbhand Bayer Pharma Ag and action medeor.V for the financial and technical support. Particular thanks are due to those who led this important process to its completion, Mrs Stella M. Mpanda Director, Childbirth Survival International, and Members from the secretariat of National Council for Technical Education (NACTE) for facilitating the process. Finally, I very much appreciate the contributions of the tutors and content experts representing PTIs, hospitals, and other health training institutions. Their participation in meetings and workshops, and their input in the development of this training manual/facilitators guide have been invaluable.

The session contents are based on sub-enabling outcomes and their related tasks of the curriculum for Basic Technician Course in Pharmaceutical Sciences. This module content is for anatomy and physiology. The module sub-enabling outcomes and their related task are indicated in the basic technician certificate in pharmaceutical science (NTA level 4) curriculum. Target Audience This module is intended for use primarily by tutors of pharmaceutical schools. The module’s sessions give guidance on the time, activities and provide information on how to teach the session. The sessions include different activities which focus on increasing students’ knowledge, skills and attitudes. Organization of the Module The module consists of thirty eight (38) sessions; each session is divided into several parts as indicated below: • Session Title: The name of the session • Total Session Time: The estimated time for teaching the session, indicated in minutes • Pre-requisites: A module or session which needs to be covered before teaching the session. • Learning Tasks: Statements which indicate what the student is expected to learn by the end of the session • Resources Needed: All resources needed for the session are listed including handouts and worksheets • Session Overview: The session overview box lists the steps, time for each step, the activity or method used in each step and the step title • Session Content: All the session contents are divided into steps. Each step has a heading and an estimated time to teach that step as shown in the overview box. Also, this section includes instructions for the tutor and activities with their instructions to be done during teaching of the contents • Key Points: Key messages for concluding the session contents at the end of a session This step summarizes the main points and ideas from the session, based on the learning tasks of the session • Evaluation: The last section of the session consists of short questions based on the learning tasks to check the understanding of students. • Handouts: Additional information which can be used in the classroom while teaching or later for students’ further learning. Handouts are used to provide extra information related to the session topic that cannot fit into the session time. Handouts can be used by the students to study material
