Document Summary

Divisions of the skeletal system: 206 bones in the human body, axial skeleton. Skull, hyoid bone, vertebrae, ribs, sternum, auditory ossicles: appendicular skeleton. Upper and lower limbs and pelvic and pectoral girdles. Bone surface markings: surface features: ridges, projections, openings, depressions, specific functions: Hyoid bone: unpaired (floating bone, does not articulate with any other bone, attachment point for tongue muscles, attachment point for neck muscles that elevate larynx during speech and swallowing. Vertebral column: supports weight of head and trunk, protects the spinal cord, allows spinal nerves to exit the spinal cord, provides site for muscle attachment, permits movement of head and trunk, 26 vertebrae. 7 cervical, 12 thoracic, 5 lumbar, 1 sacral (5 fused), 1 coccygeal (4 fused) Intervertebral discs: fibrocartilage, located between vertebral bodies, provides support. Kin 1a03 human anatomy and physiology: absorbs shock and permits minimal movement.
