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.)
