Endocrine by Jasmine Valdez per.2
Major functions of the endocrine system
metabolism control
growth and development
emotions and mood
fertility
sleep
blood pressure
Compare and contrast steroid and non-steroid hormones
steroid cells have protein receptors inside target cells specifically for them
estrogens
progesterone
androgens
non-steroid cells have a binding site in the target cells
proteins
modified amino acids
small peptides
They are similar because they both have to go in target cells.
Major endocrine organs/glands
pineal gland produces and secrete melatonin (in the brain)
hypothalamus helps keep the organs inside the body functioning (organ: pituitary gland)
parathyroid in the brain releases calcium into the bloodstream (organ: parathyroid glands)
thymus in between the lungs produces white blood cells called t-lymphocytes (target t-lymphocyte cells in blood)
liver secretes erythropoietin for blood cell production
pancreas under liver secretes hormones as an endocrine gland and digestive juice into he digestive tract as an exocrine gland (targets muscle and primarily liver)
follicle-stimulating hormone controls the menstrual cycle for women and the production of sperm for men (ovaries in women and testes in men)
kidney produce urine and works to remove waste from your body
adrenal cortex produces many hormones and helps the kidneys control the amount of salt in the blood (target all tissues but primarily kidneys)
thyroid-stimulating hormone and they control the secretion of the thyroid gland (targets most tissue and bones)
homeostatic mechanisms of hormone regulation
positive feedback controls the release of oxytocin
negative feedback:controls the release of hormones from as homonre levels rise the hormones exert its effects further secretion is inhibited by negative feedback and then hormones secretion decreases
Diseases associated with the endocrine system
type 1 diabetes: beta cells are destroyed so insulin production decreases or stops
type 2 diabetes: insulin is produced but not being recognized by cells
addison disease: hypsecretion og glucorticoids and mineralocorticoids
cushing syndrome: hypersecretion of adrenal cortial hormones
