Key Points
- Anterior Pituitary
- One of two lobes of pituitary gland, located beneath the Hypothalamus
- Regulated by Hypothalamus
- By hormones in hypophyseal portal system
- blood capillaries that enable hormones secreted from the hypothalamus to directly reach the anterior pituitary without being diluted in the circulation
- By hormones in hypophyseal portal system
- Glandular tissue releases 6 peptide hormones
- Follicle Stimulating Hormone (FSH)
- Stimulates the growth of ovarian follicles and spermatogenesis
- Luteinizing Hormone (LH)
- Acts on ovaries to stimulates the production of estrogen in females
- Acts on testes to stimulate the production of testosterone in males
- Adrenocorticotropic Hormone (ACTH)
- Acts on adrenal gland to stimulate the production of cortisol
- Thyroid Stimulating Hormone (TSH)
- Acts on thyroid gland to stimulate the production of thyroid hormones T3 and T4s
- Growth Hormone (GH)
- Directly acts to stimulates muscle, bone, and other cell growth
- Prolactin
- Directly stimulates the production of milk from mammary glands
- β-endorphins
- Follicle Stimulating Hormone (FSH)
