ground substance and extracellular fibers
Where are accessory structures located and what are some?
dermis, hair nails, glands
What are osteocytes, osteblasts, osteclasts?
osteocytes - mature bone cells
osteoblasts - build bone
osteoclasts - eat bone
Where is the zygomatic process and the temporal process?
Temporal bone and zygomatic bone
Explain negative versus negative feedback, with examples.
Negative: different direction, body temp
Positive: same direction, blood clotting and child birth

Cushions organs, provides support,
Deep dermis of skin, epithelial lining, around joints, between muscles
Explain apocrine, merocine, and holocrine.
apocrine: apart
holocrine: die
merocine: no damage
Compare parathryoid hormone to calcitonin (exact examples)
PTH - stimulate osteoclast
increase intestinal absorption
inhibit calcium excretion
Calcitonin - inhibit osteoclast
decrease intestinal absorption
increasing calcium excretion
