Periosteum
Thin membrane covering bone
Epiphysis
End of long bone where bone growth takes place
Diaphysis

Diaphysis function
Transport oxygen.
Immune support
Mineral & fat storage
Metaphysis

Endochondral ossification?
Bone develops first as hyaline cartilage in the embryo, then
becomes ossified
Intramembranous ossification
Osteoblasts lay down bone between two layers of fibrous connective tissue.
e.g. SKULL
Calcium Homeostasis
the regulation of the calcium concentration in the extracellular fluid

a rounded prominence on bone end
Trochanter
bony protuberances by which muscles are attached to the thigh bone.
Tubercle
small rounded projection or protuberance
