Growth Hormone

Growth Hormones are released by interaction with another hormone, a growth hormone releasing hormone. It is released by the Hypothalamus and it causes the Pituitary gland to release growth hormone.

GH is secreted by Somatotrophs in the anterior pituitary

GH targets the Liver and other tissues, like the adipose tissue to secrete IGF-1.

When GH activates the secretion of IGF-1, IGF-1 stimulates proliferation of cartilage cells resulting in bone growth.

Thyroid Stimulating Hormone

Thyroid Stimulating hormone is produced when the hypothalamus releases thyrotropin releasing hormone which in turn initiates the pituitary gland to release TSH

TSH is secreted from cells in the anterior pituitary called thyrotrophs

Then through positive feedback, oxytocin releases more and more of itself to target the smooth muscles of the uterine to assist in contraction during the labouring process.

Parathyroid hormone

When the body detects that calcium levels are beginning to drop, the parathyroid gland releases Parathyroid hormone into the kidney tubules and blood. PTH then forces the Bones to release more Calcium and in turn, raises the level of calcium in the body.

Calcitonin

Calcitonin is the opposite of PTH. When Calcium levels get too high, the Anterior pituitary releases ACTH to target the Thyroid, in an effort to have the thyroid releases Calcitonin.

Once Calcitonin is released, it filters into the blood and kidney tubules to decrease the level of Calcium in the body.

Insulin

When the body senses that sugar levels are too high, the Hypothalamus tells the Pancreas to release Insulin.
Released from the Beta cells, Insulin then targets all cells, specifically the liver and skeletal muscle, to gather and store glucose as glycogen.

Glucagon

Glucagon is the opposite of Insulin. Secreted the same way as insulin, Glucagon is released when blood levels are too
