Does parathroid hormone stimulate osteoclast?
Yes, probably.
Parathyroid hormone functions to stimulate activity in?
It stimulate the re absorption of calcium. It removes excess phosphates from the body
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
What is the hormone that activates Vitamin D on blood calcium levels?
Cholecalciferol is a steroid hormone that regulates body levels of calcium. It is a form of Vitamin D. Parathyroid hormone increases the concentration of calcium in the blood.
Which is greater when blood calcium levels when parathyroid hormone is increased or decreased?
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
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 are bone cells that respond to the parathyroid hormone to destroy bone matrix and release calcium into the blood?
An osteoclast.
Does parathroid hormone stimulate osteoclast?
Yes, probably.
Does calcitonin cause a decrease in blood calcium ion levels?
The hormone Calcitonin has the effect of reducing blood calcium levels. The hormone comes from the thyroid gland and works in basically three ways. 1. It works to slow absorption of calcium by the intestine. 2. It also inhibits the osteoclast (cells in bone that break down old bone tissue) that raise blood calcium levels. 3. It causes osteoblast (cells in bone that lay down new bone matrix) to form new bone. This explanation is at it's simplest form of course.
What happens if you have calcium deficiency?
Chemorecptors in blood measure the Ca level If there is too little Ca, the parathyroid releases its hormone to release Ca from bone tissue (termed osteoclast), once levels are back to body norm, inhibitory hormone tells the parathyroid hormone to stop releasing its hormone
Alcohol inhibits the secretion of what hormone?
antidiuretic hormone(ADH)
Which hormone inhibits release of prolactin?
dopamin
What plant hormone inhibits abscission?
auxin
What is the functions of the thyroid and parathyroid glands in relation to bone?
Parathyroid hormone (PTH) raises calcium levels in the blood when it's sensed that calcium levels are a bit lower than they ought to be. 99% of your body's calcium in the bones, so it stands to reason that PTH acts on bone to have it release calcium into the bloodstream. Indeed, this is exactly how the hormone works. A detailed mechanism for how this occurs is given in: http://en.wikipedia.org/wiki/Parathyroid_hormone Cheers.
What are some problems that elderly people might have as a result of decreasing hormone production?
They have a decrease in Vitamin D which inhibits the absorption of calcium in their bones which in turn leads to bone loss or osteoporosis.
Is insulin a steroid hormone?
Insulin is an anabolic hormone as: 1) it promotes glycogen synthesis & inhibits glycogenolysis and gluconeogenesis in carbohydrates. 2) it promotes lipogenesis & inhibits lipolysis. 3) promotes protein synthesis & inhibits protein degradation
Parathyroid hormone functions to stimulate activity in?
It stimulate the re absorption of calcium. It removes excess phosphates from the body
