Many of the body’s hormones are controlled by a negative and positive feedback system. Choose one of these hormones and discuss what this hormone controls, which gland secretes it, what causes it to be secreted and what turns off and on that secretion.
Homework Answers
Answer
Hormone : Calcitonin
Calcitonin is a hormone that is controlled by a
negative feedback system.
- Calcitonin regulates calcium concentration in the blood. It helps in maintaining calcium homeostasis.
- Calcitonin is released from parafollicular cells of the thyroid gland.
- When blood clacium levels increases above normal, calcitonin is secreted.
- It functions to deposit calcium into the bones by acting on osteoblasts cells.
- Once, the blood calcium levels return to normal, the secretion of calcitonin is turned off.
When blood calcium levels decrease below normal, a hormone called
PTH (Parathyroid hormone) inibits the release of calcitonin.
PTH has antagonistic effects on blood calcium levels to that of the calcitonin.
