Anatomy Flashcards
Skeletal system
Composed of fibrous tissue bound together consisting 1/3 animal matter and 2/3 mineral matter
- support soft parts of body
- protect organs
- attachment to muscles
- provide levers for body movement
Cranium
Cranium-8 bones
Face-14 bones
Frontal bone Ethmoid bone Temporal bones Parietal bones Occipital bone Sphenoid bone
Frontal bone
Forehead and upper part of orbits
Ethmoid bone
Spongy bone found between the eye sockets that form part of the nasal cavity
Temporal bone
Ear region form the sides of the head
Parietal bones
Top crown and sides of cranium
Occipital bone
