Which type of bone cell is stimulated by calcitonin?
Osteoclast
What is the relationship between estrogen and osteoclast function and how that relates to esteoperosis?
estrogen decreases osteoclast(bone reduction remodeling) which decreases osteoporosis. promotes osteoblast activity in bone formation. keeping calcium in bones and keeping bone density/integrity.
Eroding activity of this cell remodels and expand the medullary cavity?
osteoclast
What type of cell do pth activate?
Osteoclast
What is the effect of osteoclast cells on blood calcium level?
Osteoclastic activity increases the blood calcium level. Osteoblastic activity nullify the effect of osteoclastic activity. Both go hand in hand to rearrange the orientation of calcium lines in the bones, as per requirement of the stresses on the bones.
What hormone inhibits osteoclast activity when blood calcium levels rise above normal?
Calcitonin! :)
Which type of bone cell is stimulated by calcitonin?
Osteoclast
Does the function of the hormone calcitonin stimulate osteoclast activity?
osteoblast activity would increase since calcitonin's role is to decrease blood calcium. there would be extra Ca in the blood for the osteoblast to pick up and utilize. Calcium homeostasis is very tightly regulated and continuous. All the things you learn about calcium homeostasis will be occurring at the same time so try not to get confused and look at the big picture AKA what will the end results be. Hope that helped!

What hormone decreases blood calcium hormones?
Calcitonin decreases calcium levels in the blood. A good way to remember it is "Calcitonin tones down the calcium."Calcitonin (just remember calciTONin, tones down blood calcium)
What stimulates osteoclast activity?
calcitnin
Eroding activity of this cell remodels and expand the medullary cavity?
osteoclast
What hormone pairs are antagonists that regulate blood calcium ion levels?
Parathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it.
What may occur if calcitonin is hypersecreted?
Low blood calcium. Calcitonin decreases blood calcium therefore it would result in an even lower amount of calcium.
Which hormone decrease calcium?
Calcitonin decreases the calcium level.It also lowers the phosphate level.
What type of cell do pth activate?
Osteoclast
What is the purpose of hormone calcitonin function?
Calcitonin is a 32-amino acid linear polypeptide hormone that is produced in humans primarily by the parafollicular cells (also known as C-cells) of the thyroid, and in many other animals in the ultimobranchial body.[2] It acts to reduce bloodcalcium (Ca2+), opposing the effects ofparathyroid hormone (PTH).[3] It has been found in fish, reptiles, birds, and mammals. Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant to regulation of normal calcium homeostasis.[4]http://en.wikipedia.org/wiki/Calcitonin
