Know specifics of each hormone

Erythropoietin

is a peptide that is found in the kidney and increases red blood cell synthesis in bone marrow

Atrial Natriuretic Factor (ANF)

peptide originating in the heart that targets the kidneys to increase in urination in order to reduce blood pressure

Estrogen

steroid produced in the ovaries and placenta that is responsible for female characteristics and endometrial growth

Progesterone

steroid produced in the ovaries and placenta that promotes endometrial secretion and functions in pregnancy

Testosterone

steroid produced in the testes that is responsible for male characteristics and spermatogenesis

Insulin

peptide secreted by the beta cells in the endocrine pancreas that decreases blood glucose concentration and increases glycogen and fate storage

Glucagon

peptide secreted by the alpha cells in the endocrine pancreas that increases blood glucose concentration and decreases glycogen and fat storage

Somatostatin

peptide secreted by the SS-delta cells in the endocrine pancreas that inhibits many digestive processes

Cortisol

steroid originating in the adrenal cortex that is a long term stress response, which increases blood glucose concentration and protein catabolism while decreasing inflammation and immunity

Aldosterone

steroid in the adrenal cortex that increases sodium ion reabsorption in the kidneys to increase blood pressure

Sex steroids

originate in the adrenal cortex that are not normally important but may overproduce causing masculinization or feminization in the case of an adrenal tumor

Epinephrine

modified amino acid originating in the adrenal medulla that is a rapid sympathetic stress response

Thymosin

peptide found only in children that functions in Tcell development during childhood (thymus)

Parathyroid Hormone (PTH)

peptide found in the parathyroid that raises calcium ion concentration of serum in bones, kidneys, and small intestine

Calcitonin

peptide produced in the Thyroid C cells that lowers calcium ion concentration in the serum of bones and kidneys

Thyroid Hormone

modified amino acid from the thyroid that is necessary for physical and mental development in children and increases metabolic rate and temperature in adults

Antidiuretic Hormone

peptide released from the posterior pituitary that promotes water retention in the kidneys

Oxytocin

peptide originating in the posterior pituitary that functions in milk letdown in the breasts and contraction in the uterus

Luteinizing Hormone

peptide release from the Anterior pituitary (gonadotropic) that functions in ovulation in the ovary and testosterone synthesis in the testes

Follicle Stimulating Hormone

peptide (anterior pituitary gonadotropic) that functions in follicle development in the ovaries and spermatogenesis in the testes

Thyroid Stimulating Hormone

peptide released by the tropic anterior pituitary that increases synthesis and release of thyroid hormone by the thyroid

Adrenocorticotropic hormone

peptide released by the tropic anterior pituitary that increases growth and secretory activity in the adrenal ctx

Growth Hormone

peptide originating in the anterior pituitary that increases bone and muscle growth and cell turnover

Prolactin

anterior pituitary peptide that functions in milk production in the mammary gland

Releasing and inhibiting factors

hypothalamus peptides that modify activity in the anterior pituitary
