Quiz 3 Flashcards
Tropic Hormones
Hormones whose targets are other endocrine glands
ADH
Antidiuretic hormone: stimulates water reabsorption
Oxytocin
Promotes uterine contractions during labour and stimulates milk production
TSH
Thyroid, stimulating hormone: stimulates thyroid to release thyroxin
ACTH
Adrenocorticotropic hormone: stimulates adrenal cortex to produce cortisol, aldosterone, and sexual hormones
Gonadotropic hormones
FSH: follicle, stimulating hormone
LH: luteinizing hormone
FSH
Follicle stimulating hormone
- sperm and egg production
LH
Luteinizing hormone
- sex hormone production( testosterone/estrogen plus progesterone)
Prolactin
Sustain milk production
hGH
Human growth hormone
- Target, soft tissue and bones
- increase protein, synthesis, cell division, growth, breakdown, and release of stored body fat
Thyroxin
Stimulated by the release of TSH
- Stimulates most cells to increase metabolism of carbohydrates, fats, proteins
Hypothyroidism
Low quantities of thyroxin produced
- lack of growth and mental delays in children
-Fatigue and weight gain in adults
Hyperthyroidism
Overproduction of thyroxin
- anxiety, insomnia, and weight loss
Calcitonin
Regulates high blood calcium
- lowers blood calcium
- intestines of absorb less, bones deposit more, kidneys, reabsorbed less
Parathyroid hormone
Released by parathyroid gland
- increases blood calcium
- intestines absorb more, bones release more, kidneys, reabsorb more
Adrenal medulla
Inner layer of the adrenal gland
- short term stress response
What is made in the adrenal medulla
Sympathetic neuron, stimulate the production of epinephrin and nor epinephrin
What do epinephrine and norepinephrine
Convert glycogen to glucose to raise blood glucose levels
- increase heart rate, breathing rate, dilate, blood vessels, and pupils
Adrenal cortex
Outer layer of the adrenal gland
- long-term stress response
Cortisol
Stimulated by a ACTH
- raise blood glucose
- natural anti-inflammatory
Aldosterone
Mineral corticoid
- Stimulates sodium absorption and potassium secretion levels in the blood
- increase his blood pressure
Pancreas
Both an endocrine and exocrine gland
Insulin
Produced by the Islet cells and released in response to high blood glucose
Cells take in glucose
Liver stores glucose as glycogen
Fat cells buildup
Glucagon
Produced by alpha islet cells and released in response to low blood glucose
Liver converts glycogen to glucose
Fat cells breakdown
Muscle cells breakdown
