Document Summary

Fundamentals of anatomy and physiology chapter 6: bone and bone structure. Skeletal system: bones (about 206 total, axial skeleton 80 bones, bones of skull, thorax, and vertebral column. Form longitudinal axis of body: appendicular skeleton 126 bones, bones of the limbs and girdles that attach them to the axial skeleton, associated cartilages. Skeletal system function: support, protection, movement, store minerals and lipids, produce blood cells. Bone classification: classified according to shape and structure, flat bones. Thin, roughly parallel surfaces: examples: cranial bones, sternum, ribs, scapulae, protect underlying soft tissues, provide surface area for skeletal muscle attachment, sutural bones. Irregular bones formed between cranial bones: number, size, and shape vary. Long bones: relatively long and slender, examples: various bones of the limbs. Irregular bones: small and boxy, examples: bones of the wrist (carpals) and ankles (tarsals, sesamoid bones, small, flat, and somewhat shaped like sesame seed, develop inside tendons of knee, hands, and feet.
