Hormones Somatropins: growth of the body Thyrotropins: stimulates metabolism Corticotropins: stimulates secretion of glucocorticoid steroid hormones from adrenal cortex cells Lactotropins: maturation of mammary glands Gonadotropins: regulates normal growth, sexual development, and reproductive function
Maintaining Homeostasis The pituitary gland releases hormones throughout the body when they are needed to maintain homeostasis.
Feedback Mechanisms & Antagonistic Hormones The release of most hormones is controlled using negative feedback mechanisms. The hypothalamus detects changes in the body through the peripheral nervous system and senses the change needs to be fixed. Then it sends a message to the pituitary to release the hormone that fixes the problem.
Releasing & Release- Inhibiting Hormones Releasing: contains six secretory cells that release their hormones in response to hormones reaching them from the hypothalamus Release-Inhibiting: inhibits the release of hormones -growth hormone inhibiting hormone -prolactin inhibiting hormone
Failure of the Pituitary Gland Since it is the control for other glands in the body, it can stimulate or inhibit the release of hormones in other glands, like the adrenal glands, thyroid glands, or sex organs. Can also cause gigantism or dwarfism
Corrections of the Pituitary Gland Depending on the cause there are many different treatments. Injections or medication can be taken to replace hormones that were not secreted by the pituitary gland.
