Endorcine system - Matillda Garcia P.2 - Coggle Diagram
Endorcine system - Matillda Garcia P.2
Compare and contrast non - steroid and steroid
differences
steroid
crosses cell membrane
combines with a protein receptor on nucleus
non - steroid
bind to receptor molecule on cell membrane
activates molecules of adenlatecyclase
similarities
reaches target cells
Major Functions
secretes hormones into body fluids to affect the target cells
maintains homeostasis
Homeostatic mechanisms of hormone regulation
controls blood glucose when too high or too low and does the same for blood pressure
Major Endorcine glands
pancreas
Hormones: Glucagon and Insulin
Glucagon brings up blood glucose when too low. Target cell is the liver
Insulin brings down blood glucose level when too high. Target cell is the liver as well
parathyroid
hormone: PTH
Parathyroid hormone increases the blood calcium and it stimulates the kidneys to conserve the calcium
pituitary
hormones of posterior lobe are
Oxytocin contracts muscles in the uterine wall during child birth and lets milk come in
antidiuretic makes the kidneys conserve water and reduces the amount of water release by urine
hormones of the anterior lobe are GH, PRL, TSH, ACTH, FSH and LH
GH: growth hormone that is responsible for growth. Target cells are bone, joints and muscle
PRL: is prolactin which is responsible for milk production. Target cell is Mammary gland
TSH is a thyroid stimulating hormone which regulates the hormone secretion from thyroid gland. Target cell is thyroid gland
ACTH is adrenocorticotropic hormone which controls the secretion of certain hormones from the adrenal cortex
FSH is a follicle stimulating hormone which is responsible for the egg development in female and sperm cell production in males, Target cells are the male and female reproductive organs
LH is a luteinizing hormone which promotes the secretion of sex hormones. Target cells are male and female reproductive organs
thryoid
hormones: T4, T3 and Calcitonin
T4 is thyroxine which affects almost all of the body's systems like the heart and digestive functions, metabolism, brain development etc.
T3 is Triiodothyronine which has the same function of T4 but just 5x more potent
Calcitonin lowers blood calcium and phosphate ion concentrations
adrenals
epinephrine and norepinephrine both are hormones of the adrenal glands and they increase heart rate, blood pressure, blood glucose, dilate airways and decrease digestive activities
kidney and thymus glands
kidneys secrete the hormone erythropoietin which is for blood cell production
thymus gland secretes thymosin which is essential for body immunity
reproductive glands
ovaries produce estrogen and progesterone
regulates mammalian reproduction
placenta produces the same as ovaries and gonadotropin
gonadotropin regulates testie and ovaries function
testes produce testosterone
testosterone regulates male sex drive
pineal body
melatonin is the hormone of pineal gand. It helps you sleep
diseases
diabetes
graves disease
addisons disease
hyperthyroidism and hypothyroidism
Major endorcine organs
ovaries
secrete estrogen and progesterone
vital to reproductive development and fertility
testes
produce sperm cells and male sex hormones
thyroid
releases and controls thyroid hormones that control your metabolism
adrenal glands
makes hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.
