Endocrine system: HORMONES

OXYTOCIN

MADE IN: hypothalamus

SENT TO: post. pituitary gland

TARGETS: uterus muscle + breast tissue

ACTION: contractions to start childbirth, milk to flow during nursing

Antidiuretic hormone (ADH)

MADE IN: hypothalamus

SENT TO: post. pituitary gland

TARGETS: kidneys

ACTION: kidneys to reabsorb water instead of making it urine; holds it during the night

prolactin

MADE IN: ant. pituitary gland

TARGETS: breast tissue

ACTION: milk production

growth hormone (GH)

MADE IN: ant. pituitary gland

SENT TO: liver

TARGETS: liver, second hormone targets m muscles and bones

ACTION: tells muscles and bones and other organs to grow via mitosis

follicle-stimulating hormone

MADE IN: ant. pituitary gland

TARGETS: ovaries and testes

ACTION: ovaries: egg production

testes: sperm production

luteinizing hormone (LH)

MADE IN: ant. pituitary gland

TARGETS: ovaries and testes

ACTION: ovaries: ovulation, estrogen + pro estrogen

testes: testosterone production

thyroid stimulating hormone (TSH)

MADE IN: ant. pituitary gland

TARGETS: thyroid gland

ACTION: regulates thyroid releasing its own drenoahormones

adrenocorticotropic hormone

MADE IN: ant. pituitary gland

TARGETS: adrenal cortex

ACTION: adrenal cortex producing its own hormones

melatonin

MADE IN: pineal gland

TARGETS: many tissues when light levels are too low

ACTION: make you feel calm and sleepy

triiodothyronine (T3)

MADE IN: thyroid gland

TARGETS: most organs

ACTION: increase metabolic rate. high levels= fast metabolism

thyroxine (T4)

MADE IN: thyroid gland

TARGETS:most organs

ACTION: converted to T3 which regulates metabolism

Definition

calcitonin

MADE IN: thyroid gland

TARGETS: bones

ACTION: triggers calcium ions to exit the bloodstream and go into the bones

parathyroid hormone

MADE IN: parathyroid gland

TARGETS:bones

ACTION: triggers calcium ions to exit bones and go into the bloodstream hymosint

thymosin

MADE IN: thymus gland

TARGETS: T cells

ACTION: t cells to mature

epinephrine (adrenaline)

MADE IN: adrenal medulla

TARGETS: most organs

ACTION: “fight or flight” and stress recognition, increase heart rate/blood pressure/ blood sugar/blood flow, pupil dilation

norepinephrine (noradrenaline)

MADE IN: adrenal medulla

TARGETS: most organs

ACTION: “fight or flight” and stress recognition, increase heart rate/blood pressure/ blood sugar/blood flow, pupil dilation orc

cortisol

MADE IN: adrenal cortex

TARGETS: all tissues

ACTION: production of glucose: released in stressful situations

aldosterone

MADE IN: adrenal cortex

TARGETS:kidneys

ACTION: kidneys to keep salt and water in the blood/ raise blood pressure

estrogen

MADE IN: ovaries

TARGETS: many targets in females reproductive system

ACTION: to build up to prep for pregnancy, secondary sex charactersitics

progesterone

MADE IN: ovaries

testosterone

MADE IN: testes

TARGETS: male reproductive system

ACTION: production of sperm, secondary sex characteristics

insulin

MADE IN: pancreas
