Deviation From Normal : Low level of Vitamin D
Receptor : Bone Cell
Control Center :parathyroid gland
Efferent Pathway :parathyroid hormone (effects on bone because of inhibition production of hormone)
Effector :Stimulating Osteoclasts and inhibiting Osteoblasts
Response : When blood calcium levels are low, parathyroid hormone (PTH)is released, PTH stimulates osteoclasts , also PTH inhibits osteoblasts.Osteoclasts break down bone tissue, releasing calcium into the bloodstream.PTH also inhibits osteoblasts, which are cells involved in bone deposition. By reducing calcium deposition in bone leading not enough calcium, our bones become more fragile, leading to osteoporosis.
