Document Summary
Depression/openings: allow the passage of soft tissues, blood vessels, and nerves; form joints. Processes: projections or outgrowths that form joints and serve as attachment points. Axial skeleton: (80 bones) skull, hyoid, ribs, sternum, vertebra: skull: protects and supports brain; forms nasal cavity, orbits, and paranasal sinuses. Cranial bones: frontal, parietal, temporal, occipital, sphenoid, ethmoid. Facial: mandible, maxilla, zygomatic (cid:498)check bone(cid:499), nasal, lacrimal, palatine, inf. Paranasal sinus: cavity within certain cranial and facial bones; lined with mucus conchae, vomer membranes, warms the air, reduces weight in skull, resonates sound. Hyoid: supports tongue by attaching to muscles; does not articulate with anything. Cervical vertebrae: smallest of vertebrae, atlas c1, axis c2, bifid spinous process. Thoracic vertebrae: larger, long spinous process is long; articulates with ribs. Lumbar vertebrae: largest, support body weight, kidney-shaped bodies, short spinous process. Sacrum: (5 fused) at bottom of column, contains openings called sacral canal. Coccyx: (4) fused; lowest part; tail bone: intervertebral discs, spinal curvatures:
