Where is it Located? The Pituitary Gland is located at the base of the brain, where a pituitary stalk attaches to the hypothalamus The gland is about 1 cm in diameter
Basic Anatomy of the Organ The gland consists of an anterior pituitary, or anterior lobe, and a posterior pituitary Creates and releases various hormones that affect several organ throughout the body The pituitary gland work together with the hypothalamus which stores and releases hormones into the bloodstream
General Function of Organ The Pituitary gland produces critical hormones, which are chemical substances that control various bodily function The pituitary gland is divided into three sections -The Anterior Lobe -The Posterior Lobe -The Intermediate Lobe
Anterior Lobe involved in the development of the body, reproduction, and sexual maturation -hormones which are produced by the anterior lobe regulate growth and stimulate thyroid and adrenal glands -it also creates prolactin which enables new mother to produce milk Adrenocorticotropic hormone: stimulates adrenal glands to produce hormones Follicle-stimulating hormones: ensures normal functioning of the ovaries and testes Growth hormone: is important in early years to maintaining a healthy body and growth for a child
Posterior Lobe Produces: Anti-Diuretic hormones: prompts the kidneys to increase water absorption in the blood Oxytocin: involved multiple processes such as stimulating breast milk production and contracting the uterus during childbirth
Intermediate Lobe Responsible for releasing hormones which stimulate the melanocytes: cells which control pigmentation -like skin color with the help of melanin contains very few blood vessels
Hypothalamus Its primary function is to maintain the body in homeostasis it is able to link the nervous and endocrine system by a way of the pituitary gland -the hypothalamus produces specialized neuron clusters called neurosecretory cells which produce hormones such as Antidiuretic hormone and oxytocin
Diseases or Abnormalities Pituitary tumors are the most common which are secretory and nonsecretory -Secretory: secrete too much of a hormone -Non-Secretory: do not secrete excess hormones if one has a secretory tumor-overproduces thyroid stimulation hormone, will cause hyperthyroidism Pituitary apoplexy- function in the pituitary gland can be suddenly disrupted creating a life threatening shortage of vital hormones
