Document Summary
Osteology: the science and study of bones- composition, structure, development, function. 5. mineral bank : reservoirs of minerals to be tapped by bodies (ex: pregnant women deficient in calcium will resorb own bone to nourish fetus) 6. energy reserve: adipose tissue stored in marrow as well. Sagittal plane: cuts body into left and right halves. Coronal plane: cuts body into front and back halves. Transverse plane: cuts body into top and bottom halves. Axial skeleton: bones of head/ trunk of vertebrae. Categorizing the 206 bones long bones: large, tubular bones of the limbs with articular ends (6 pairs, 12 total) Short bones: like long bones, with tubular shafts and articular ends, but much smaller (58 total) Flat bones: thin, wide bones for protection and muscle attachment, not tubular!! (35 total) ribs, sternum irregular bones: blocky or chunky depending on the function the bone performs (65 infracranial & many cranial)
