Question Answer
Antidiuretic Hormone (ADH) Source: Posterior Pituitary Target: Kidney, sweat glands, arterioles Action: conserve water by decreasing urine volume, perspiration, and in creasing blood pressure
Oxytocin (OT) Source: Posterior Pituitary Target: Uterus, mammary glands Action: Stimulate contraction of uterine muscles during childbirth; stimulates ejection of milk from mammary gland after childbirth
Human Growth Hormone (HGH) Source: Anterior Pituitary Target: Liver, skeletal muscles, cartilage, bone Action: Promote growth of body cells by increasing protein synthesis, promote tissue repair, increase blood glucose
Thyroid-stimulating hormone (TSH) S: Anterior Pituitary TO: Thyroid Gland A: Stimulate synthesis and secretion of thyroid hormones
Melanocyte stimulating Hormone (MSH) S: Anterior Pituitary TO: Brain, skin A: Not clearly known. May influence brain activity. Affects skin pigmentation
Luteinizing Hormone (LH) S: Anterior Pituitary TO: Ovaries, testes A: Female - trigger ovulation, stimulate estrogen secretion Male - stimulate secretion of testosterone
Follicle-stimulating Hormone (FSH) S: Anterior Pituitary TO: Ovaries, testes A: F - initiate monthly development of oocytes; stimulate secretion of estrogen M - stimulates sperm production
Prolactin (PRL) S: Anterior Pituitary TO: Mammary glands A: Stimulates milk production and secretion
Thyroid Hormones (T3 and T4) S: Thyroid glands TO: Whole body Action: Increase metabolic rate; stimulate protein synthesis; increase use of glucose and fatty acids for energy; accelerate body growth; contribute to development of nervous sytem
Calcitonin S: Thyroid Gland TO: Bones, kidneys A: Decrease blood calcium; promote bone formation; inhibits osteoclasts
Parathyroid Hormone (PTH) S: Parathyroid Gland TO: Bones, kidneys A: increases blood calcium; promote bone resorption; limits loss of calcium in urine; stimulates osteoclasts
Epinephrine / Norepinephrine S: Adrenal Medulla TO: Heart, skeletal muscle, liver, adipose tissue, lungs A: Fight/flight response; increase HR and BP; increase blood flow to heart, liver, skeletal muscle and adipose tissue; dilate airway; increase blood glucose; enhance sympathetic division of ANS
Aldosterone S: Adrenal Cortex TO: Kidneys A: Increase blood sodium and water; decrease blood potassium; adjust blood pressure and blood volume
Cortisol S: Adrenal Cortex TO: Liver, muscle, adipose tissue A: Increase protein and lipid breakdown; increase glucose formation; dampens inflammation and decreases immune response
Insulin S: Pancreas TO: Liver, muscle, adipose tissue A: Lower blood glucose; promote formation of glycogen; promote cell growth and differentiation
Glucagon S: Pancreas TO: Liver, muscle, adipose tissue A: Raises blood glucose; stimulates breakdown of glycogen
Testosterone S: Testes TO: Testes A: regulate sperm production; promote development of male sex characteristics
Estrogen and Progesterone S: Ovaries TO: Uterus, mammary glands and many cells in body A: Regulate female reproductive cycle, promote development of female sex characteristics, maintain pregnancy
Melatonin S: Pineal Gland TO: Brain A: Regulates biological clock; higher levels in darkness
