Document Summary
Describe the gross structure of a long bone. Compare and contrast spongy and compact bone. Relate the hormonal regulation of bone calcium to homeostasis. Relate the pathophysiology of bone disorders (those covered) to disruption of function. Protection: especially of vital organs (heart, lung) and brain. Allow movement / lever system: due to structure of joints (articulations) Storage depot for ca and p salts homeostasis of these electrolytes (especially. Hemopoiesis: blood forming all blood cells develop in bone marrow. Carpals on your wrists tarpals on ankles. Shaft of long bone; composed of compact bone; hollow inside. End of long bone proximal (closest to midline) epiphysis and distal (furthest from midline) epiphysis. Thus for humerus proximal epiphysis is close to shoulder joint; distal is close to elbow joint. Consists of hyaline cartilage; site of growth (in length) of a long bone, aka (also known as) growth plate or epiphyseal plate.
