4
Q
osteoporosis
A
bone matrix becomes weak b/c osteoclast activity is faster than osteoblast activity
5
Q
rickets
A
lack of vitamin d causes weak/immature bone formation
misaligned vertebral column and bowed legs
6
Q
increased ca2+ homeostasis
A
- thyroid gland releases calcitonin
- osteoclast activity inhibited
- ca2+ resorption decreases
- ca2+ decreases
7
Q
decreased ca2+ homestasis
A
- parathyroid gland releases PTH
- osteoclasts release ca2+
- reabsorbed from urine by kidneys, calcium absorption in small intestine increases
- ca2+ inc
