Follicle Stimulating Hormone (FSH)
Structure: Tropic (non-steroid) Source: Anterior Pituitary Function: Stimulate the growth and maintenance of the gonads (ovaries/testes). Stimulates the synthesis of estrogen in women and maintains sperm production in men. Target: Gonads |
Decreased Gonadotropin s/s:
Women: amenorrhea, decreased axillary (armpit)/ pubic hair, sterility, atrophy (wasting away of tissue) Men: Loss of axillary/pubic hair, testicular atrophy, sterility |
|
Thyroid Stimulating Hormone (TSH)
Structure: Tropic (non-steroid) Source: Anterior Pituitary Function: Promotes and maintains the growth of the thyroid gland Target: Thyroid Gland |
Hyperthyroidism s/s:
Tachycardia, breathing hard, diarrhea, weight loss, excessive sweating, fatigue, nervousness, inattention, amenorrhea, impotence Hypothyroidism s/s: Bradycardia, dyspnea, constipation, weight gain, dry skin, aches and pain, lethargy, slowed mental processes, abnormal periods, infertility |
|
Luteininzing Hormone (LH)
Structure: Tropic (non-steroid) Source: Anterior Pituitary Function: Stimulates the formation and activity of the corpus luteum of the ovary. Causes secretion of progesterone and estrogen in the female and testosterone in the male Target: Gonads |
Decreased Gonadotropin s/s:
Women: amenorrhea, decreased axillary (armpit)/ pubic hair, sterility, atrophy (wasting away of tissue) Men: Loss of axillary/pubic hair, testicular atrophy, sterility |
|
Prolactin (PRL)
Structure: Protein (non-steroid) Source: Anterior Pituitary Function: Generating or initiating milk secretion Target: Mammary Glands |
Hypersecretion:
Lactation in nonnursing women, disruption of the menstrual cycle, decreased size of gonads, and impotence in men |
|
Growth Hormone (GH) aka: Somatotropin (STH)
Structure: Protein (non-steroid) Source: Anterior Pituitary Function: Increases protein anabolism and fat catabolism, inhibits glucose metabolism, increases blood glucose levels Target: Bones |
Excessive GH:
Adults: Acromegaly (overgrowth of small bones) - decreased life expectancy, death from HTN and DM Children: Giantism - heart failure |
|
Adrenocorticotropic Hormone (ACTH)
Structure: Tropic (non-steroid) Source: Anterior Pituitary Function: Promotes and maintains the growth and development of the cortex of the adrenal gland. It also stimulates the adrenal cortex to synthesize and secrete some of its hormones Target: Adrenal Cortex |
Excessive ACTH:
Cushings Disease (weight gain, moon face, striae, etc.) Low ACTH: Addison Disease (weight loss, anorexia, nausea and vomiting, diarrhea, skin hyperpigmentation, etc.) |
