The pituitary gland
The pituitary gland is a small, pea-sized gland found inside the skull and below the brain. As part of the endocrine system, the pituitary gland makes many different hormones that travel throughout the body. These hormones control certain body functions and tell other glands to make other hormones.
The pituitary gland is divided into 2 parts (lobes). The front part closer to the face is called the anterior pituitary gland. The back part is called the posterior pituitary gland, and it is closer to the back of the head. The pituitary gland is surrounded by bone (sphenoid bone), and it sits in a pouch called the sella turcica.
Pituitary gland hormones
The pituitary gland makes 9 different hormones. Both the anterior pituitary gland and the posterior pituitary gland make hormones.
Anterior pituitary gland hormones
The following hormones are made by the anterior pituitary gland:
Adrenocorticotrophic hormone (ACTH) tells the adrenal glands to make cortisol and other steroid hormones. Cortisol has many different jobs, such as controlling blood sugar levels and helping the body respond to stress. ACTH is also called corticotropin.
Growth hormone promotes the growth of all tissues of the body, including bones and muscles. It is needed for normal growth in children. It helps maintain body tissues in adults. Growth hormone is also called somatotropin.
Thyroid-stimulating hormone (TSH) encourages the thyroid to make and release hormones that control growth, body temperature and heart rate and change food into energy. TSH is also called thyrotropin.
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) control the sex organs. In women, FSH and LH tell the ovaries to make the female sex hormones estrogen and progesterone and control the release of eggs (ovulation). In men, FSH and LH get the testicles to make sperm and the male sex hormone testosterone. FSH and LH are called gonadotropins.
Prolactin stimulates breasts to develop and make milk after childbirth. Prolactin is also called lactotropin.
Melanocyte-stimulating hormone (MSH) causes certain cells of the skin (called melanocytes) to make melanin, which is the substance that gives skin its colour and helps protect the body from some of the harmful effects of the sun.
Posterior pituitary gland hormones
The following hormones are made by the posterior pituitary gland:
Antidiuretic hormone (ADH) keeps water in the body so that it’s not all lost. It lowers the amount of urine the kidneys make and helps control blood pressure. ADH is also called vasopressin.
A specialized organ or group of cells that produces or releases substances (such as hormones, saliva, digestive juices, sweat, tears or milk) to perform different functions in the body.
A hollow space, channel or passageway in the body.
Examples of sinuses include the air-filled spaces in the skull around the nose and eyes or a passage leading to an abscess (collection of pus). It can also refer to a channel for the passage of blood or lymph fluid.
The part of the brain below the thalamus that controls hormone production, water balance, body temperature and other activities in the body related to metabolism.
A female sex hormone that causes the female sex characteristics to develop (such as breasts) and is necessary for reproduction.
Estrogen is made mainly by the ovaries. Small amounts of estrogen are also made in the adrenal glands. It may also be produced in the lab to treat certain conditions or as a type of birth control.
A female sex hormone that prepares the uterus (womb) for pregnancy and the breasts for lactation following childbirth.
Progesterone is made mainly by the ovaries and the placenta. It may also be produced in the lab to treat menstrual problems, infertility, symptoms of menopause and other conditions or as a type of birth control.
A male sex hormone that causes male sex characteristics to develop (such as deep voice and facial hair) and stimulates the development of the male reproductive system and sexual activity.
Testosterone is made mainly by the testicles. Small amounts of testosterone are also made in the adrenal glands. It may also be produced in the lab to treat certain conditions.
The pear-shaped, hollow, muscular organ in the pelvis of females that contains and nourishes the fetus during pregnancy.
The upper, broader part of the uterus is the corpus. The lower, narrow part is the cervix.
Uterine means referring to or having to do with the uterus, as in uterine cancer.
Commonly called the womb.
the chestnut-shaped gland just below the bladder and in front of the rectum that surrounds the urethra (the tube that carries semen and urine to the outside of the body) and produces fluid that forms part of the semen.
also called prostate gland.
