endocrine system

differences between nervous system and endocrine system

nervous= neurotransmitters endocrine= hormones nervous= close to release site endocrine = far from release site

endocrine vs exocrine

endocrine secretes hormones into interstitial fluid then blood

exocrine secretes sweat, saliva, oil into ducts then cavities

8 major glands

pituitary, pineal, thymus, thyroid, parathyroid, pancreatic inlets / pancreas, adrenal, gonads

pituitary nickname, job, parts, location

master gland, controls other glands and homeostasis, anterior and posterior, below hypothalamus in brain

posterior vs anterior pituitary

post stores and releases hormones instead of producing them

thyroid gland location, job, parts,

between voice box and sternum in throat, metabolism and tissue growth, left and right lobes

parathyroid location and job

behind thyroid, helps kidneys and osteoclasts

adrenal glands location and job

above both kidneys, produces steroid hormones

pancreas location and parts

behind stomach upper abdomen, head body tail

gonads and their locations and hormones

testes: in scrotum, testosterone ovaries: sides of uterus estrogen and progesterone

pineal location and hormone

third brain venrticle, melatonin

thymus location and job

between lungs, immunity

8 major hormones

growth hormone (hgh), t3 (triidothyronine), t4 (thyroxine), cortisol, insulin, epinephrine, nonrepinephrine, glucon

hgh gland, type, job

anterior pituitary, protein, tissue growth

t4 and t3 gland, type, job

thyroid, amine, metabolism

cortisol gland, type, job

adrenal, steroid, stress

insulin gland, type, job

pancreas, protein, lower blood sugar level

epinephrine and norep gland, type, job

adrenal, amine, fight or flight

glucagon gland, type, job

pancreas, protein, raise blood sugar level

pituitary hormone # and job

7 stimulate other hormones

thyroid hormone # and job

2 metabolism

parathyroid hormone # and job

1 (PTH) increase calcium in blood

adrenal hormone # and job

3 emergency and stress

pineal hormone# and job

1 (melatonin) sleep

pancreas hormone # and job

2 (insulin and glucagon) regulates blood sugar level

testes hormone# and job

1 (testosterone) man things like sperm, deep voice, hairy body

ovaries hormone # and job

2 prepare for birth

what systems maintain homeostasis

endocrine, nervous

signaling types

endocrine, paracrine, autocrine, neutral

endocrine vs paracrine signaling

endo: hormones to far away cells para: nearby cellls

autocrine vs neutral signaling

auto: acts on same cell that releases neutral: neurotransmitters across cell gaps

where is the pituitary gland

under thalamus to right

pupouse of endocrine system

hormones into blood

purpouse of exocrine system

substances into ducts/ cavities
