Skull Radiography: Additional Projections

The skull is the bony structure that form the head in vertebrate, protecting the brain and supporting the facial features.it consist two main parts which are cranial bones and facial bones which forms the structure of the face Cranial bones; These bones protect the brain. They are 8 cranial bones:

• Frontal bone: form the forehead and upper part of the eye socket.

Parietal bones(2): form the top and upper sides of the skull Occipital bone: form the back and the base of the skull and contain formen magnum where the spinal cord enter the skull.

Temporal bone (2): found below the parietal bones; They house structure of the ears.

Sphenoid Bones : found at the base of the skull in front of the temporal bones. Help form the eye socket.

Ethmoid bones: form part of nasal cavity and eye socket.

maxilla[2];upper jaws

• Mandible; lower jaws, the only movable bones of the skull
• Zygomatic bones; cheekbones
• Nasal bones; bridge of nose
• Palatine bones; forms the back of the hard plate
• Lacrimal bones; small bones forming party of the eye socket
• Inferior nasal conchae[2];party of the nasal cavity structure
• Vomer; form the part of nasal septum

2.Facial bones

These bones are joined together by sutures, which are immovable joints that fuse the bones tightly. This structure helps protect the brain and forms a rigid framework for the chewing, facial expression and other function

FUNCTIONS OF THE SKULL

• Protection of the brain
• Support for sensory organs
• Attachment of muscle
• Shape and structure of the head

Respiratory and airway function.

… The skulls complex structure plays a central role in protection delicate tissues and facilitating essential bodily function.
