osteoblasts,
forms bone matrix
Lacumae
A tubular gap in a bone
osteocytes
Maintains bone tissue
osteoclasts
reabsorbs bone
Bone medulla
yellow
marrow in adults
* Red marrow in young
Periosteum
Thin membrane covering bone
Epiphysis
End of long bone where bone growth takes place
Diaphysis
Shaft of a long bone
Diaphysis function
Transport oxygen.
Immune support
Mineral & fat storage
Metaphysis
Contains growth plate of the epiphysis.
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
3 phases in remodelling of fractures in bone.
Inflammatory phase
Repair phase
Remodelling phase
Pneumatic bones
bones filled with air
(birds & frontal sinus)
Foramen
an opening, hole, or passage in a bone
Fossa
Shallow depression or hollow
