ch 17. Test Flashcards
Thyroxine
Tetraiodothyronine, T4-4 iodine
Growth hormone
Stimulates body cells to grow and reproduce
Follicle stimulating hormone
Gonadotropins-influence gonads (reproductive hormones)
Cortisol
Influences metabolism of glucose, proteins + fat in response to conditions that stress the body
Insulin
Decreases blood sugar by stimulating liver to form glycogen, increases protein and fat storage
Hyperthyroidism
High metabolism, underweight, protruding eyes
Pineal gland
Secretes melatonin regulated circadian rythym by increasing melatonin in low light and decreasing in high light (jet lag)
Hypothalamus
Controls anterior pituitary glands, release of hormones that stimulate other endocrine glands to release hormones
Diabetes Mellitus
Insulin deficiency, disturbs carbohydrate, protein + fat metabolism
Type 1
Auto immune, insulin dependent
Type 2
Treat w/ diet and exercise, non insulin dependent
Fractures
Can result from hyperparathyroidism ( high amounts of parathyroid)
PTH
Up Co2+ when too low, increases blood calcium and decreases phosphate
Effects of stress
Short term( epinephrine, norepinephrine, more oxygen to organs
Effects of stress
Long term (cortisle, cartobolism of glycogen)
Endocrine disorders and cancer are
Common because cancer cells can secrete hormones inappropriately
Neurotransmitters
Chemical messengers (endocrine)
ADH
Antidiuretic Hormones
Oxytocin
Released due to stretching of the uterus at term, releases OT so uterus gets smaller
Anabolic steroids
Synthetic version of sex steroid testosterone, high blood pressure, damaged liver, high heart failure, high chance of heart attack
Hyperglycemia
High blood glucose
