- Erythropoietin
- From kidney: Targets bone marrow to increase RBC synthesis
- Oxytocin
- targets breast, causes milk letdown, targets uterus, causes contractions
- Follicle stimulating hormone (FSH)
- Females: targets ovary, causes follicle development. Males: targets testes, causes spermatogenesis
- hypothalamus
- secretes releasing and inhibiting factors which modify activity of anterior pituitary
- TSH Thyroid stimulating hormone (Ant Pit) (tropic hormone)
- Increases synthesis and release of TH (thyroid hormone)
- Epinephrine (modified amino acid)
- Produced in Adrenal medulla
- progesterone(steroid)
- endometrial secretion, pregnancy
- estrogen (steroid)(ovaries/placenta)
- female characteristics, endometrial growth
- Parathyroid hormone (PTH)
- Targets bone and kidney, small intestine. Raises serum Ca2+ levels
- Atrial natriuretic factor (ANF)_
- From heart: targets kidneys. increases urination to decrease blood pressure
- Thyroid hormone (TH, thyroxine)
- Modified amino acid
- Lutenizing hormone (LH) (gonadotropic hormone)
- Females: targets ovaries, causes ovulation. Males: targets testes, testosterone synthesis
- Calcitonin
- Released by thyroid C cells
- Calcitonin
- Targets bone and kidney. Lowers serum calcium levels
- Cortisol (Steroid)(Adrenal Cortex)(glucocorticoid)
- targets longer-term stress response; increases blood glucose levels, increase protein catabolism; decreases inflammation and immunity
- Growth hormone (Ant pit)
- Increases bone and muscle growth, increase cell turnover rate
- Thyroid hormone (TH, thyroxine)
- Child: necessary for physical and mental development
- Thymosin (from thymus gland)
- T cell development during childhood (CHILDREN ONLY)
- Antidiuretic hormone (ADH)(vasopressin)
- Targets kidney, causes water retention
- testosterone (steroid)
- male characteristics, spermatogenesis
- Thyroid hormone (TH, thyroxine)
- Adult: increases metabolic rate and temperature
- ACTH (Adrenocorticotropic hormone)
- Increases growth and secretory activity of the adrenal cortex
- Aldosterone (Mineralocorticoid)(steroid)
- Targets kidney: Increases sodium reabsorption in order to increase blood pressure
