endocrine system Natalie Yracheta P5
Major functions of the endocrine system
maintaining electrolyte and nutrient balance of blood
growth and development
Major endocrine glands/organs and their functions
cranial cavity
pineal gland
melatonin
posterior pituitary gland
oxytoxcin
stimulates uterine contractions & triggers milk ejection
antidiuretic hormone
causes kidney to conserve water
anterior pituitary gland
growth hormone
stimulates an increase in size & division rate of body cell
prolactin
sustains milk production after birth
thyroid-stimulating hormone
controls secretion of hormones from TH
adrenocorticotropic hormone
stimulates adrenal cortex to release corticosteroids
follicle-stimulating hormone
stimulates follicular cells to create gametes
luteinizing hormone
promotes secretion of sex hormones
thoracic cavity
parathyroid gland
parathyroid hormone
increases blood calcium ion concentration & stimulates osteoclasts
thyroid gland
T4
stronger than T3
T3
accelerates NS growth
calcitonin
lowers blood calcium
thymus
thymosins
affects T cells
abdominal cavity
adrenal gland
adrenal cortex
mineralocorticoids
maintains BP with aldostrone
glucocorticoids
keeps blood glucose levels consistent
gonadocorticoids
converts to testerone
adrenal medulla
epinephrine
helps SNS
norepinephrine
increases alertness
pancreas
glucagon
decreases glucose blood levels
insulin
increases glucose blood levels
pelvic cavity
uterus
oxytocin
ovary
estrogen & progesterone
testes
testosterone
Compare and contrast steroid vs. non-steroid hormones and list the hormones for each
category
steroid
from cholesterol
corticosteroids
progesterone
testosterone
estrogen
oxytocin
non sterioid
from amino acid, peptides, or proteins
insulin
glucagon
FSH
LH
epinephrine
Homeostatic mechanisms of hormone regulation
negative feedback
glucose molecules enter beta cells and release insulin
insulin is transported and binds to cells causing glucose to become glucagon and glucose decreases and glucose levels stablize
Diseases associated with the endocrine system
diabetes mellitus
type 1 from hyposecretion of insulin
hypoactivity of insulin
graves disease
hypersecretion of TH
gigantism/acromegaly
hypersecretion of GH
