A&P (endocrine hormones) FUTURERN

Releasing hormones (RH)

stimulate production of hormones

Where is releasing hormone (RH) found?

Hypothalamus

Inhibiting hormone (IH)

prevent synthesis and secretion of hormones from the anterior lobe

Where is inhibiting hormone found?

Hypothalamus

TSH (thyroid stimulating hormone)

targets the thyroid gland and triggers the release of thyroid hormones

Where is TSH secreted from?

anterior pituitary gland

ACTH (adrenocorticotropic hormone)

targets the adrenal cortex - stimulates the release of glucocorticoids and mineralocorticoids

GH (growth hormone)

targets muscle and bone - stimulates growth

Where is GH (growth hormone) secreted from?

Anterior pituitary gland

FSH (follicle stimulating hormone)

targets the gonads- stimulates the maturation of sperm cells and ovarian follicles

Where is FSH (Follicle-Stimulating Hormone) produced?

anterior pituitary gland

LH (luteinizing hormone)

targets the gonads - stimulates the production of sex hormones; surge stimulates ovulation in females

Where is (LH) Luteinizing Hormone Secreted from?

anterior pituitary gland

Oxytocin (OT)

Targets uterus - stimulates contractions - targets mammary glands stimulates milk secretion

Where is oxytocin produced?

hypothalamus

Where is oxytocin released from?

posterior pituitary gland

ADH (antidiuretic hormone)

Targets kidnet (makes you pee less, more concentrated urine)

Where is T3 and T4 produced?

thyroid gland

T3 and T4

Affect cell's metabolism by increasing utilization, oxygen consumption, growth and development

Where is calcium stored?

99% in bones and 1% in blood, muscle, and other tissues

What is the adrenal medulla?

inner portion of the adrenal gland

What does the adrenal medulla secrete?

epinephrine and norepinephrine

What does epinephrine and norepinephrine do?

fight or flight response

What is the adrenal cortex?

outer layer of the adrenal gland

Mineralocorticoids (aldosterone)

targets the kidneys - increase the retention of Na+ and excretion of K+

Where is mineralocorticoids (aldosterone) produced?

adrenal cortex

where is glucocorticoids produced?

adrenal cortex

Glucocorticoids (cortisol)

Targets most tissue - released in response to long-term stressors, increase blood glucose, promotes peripheral use of lipids; anti inflammatory effects

Where is androgen produced?

adrenal cortex

Androgens (testosterone)

target most tissues - stimulate development of secondary sex characteristics

Where is the thymus gland located?

mediastinum

Where is thymosin produced?

thymus gland

Thymosin

targets lymphatic tissues - stimulates the production of T-cells

Where is insulin secreted from?

beta cells of pancreas

Insulin hormone

Targets liver - increases blood glucose

Where is GHIH (growth hormone IH)secreted from?

Pancreas

GHIH (growth hormone inhibiting hormone)

inhibits secretion of insulin and glucagon

Where is calcitriol secreted from?

Kidneys

Calcitriol

Stimulates absorption of calcium and phosphate from digestive tract

Where is renin secreted from?

kidneys

Renin

Released in response to decreased blood volume, blood pressure, or both. Ends up restricting salt and water loss in kidneys

Where is erythropoietin produced?

kidneys

Erythropoietin (EPO)

stimulates the production of red blood cells by bone marrow in response to low oxygen levels in kidneys

Glucagon

Released by alpha cells - targets liver - increases blood volume

ovaries produce

estrogen and progesterone

Estrogen

Support follicle maturation

Progesterone

hormone produced by the corpus luteum in the ovary and the placenta of pregnant women

Where is TRH secreted from?

hypothalamus

TRH (thyrotropin releasing hormone)

Secreted by hypothalamus --> triggers pituitary gland to secrete TSH
