endocrine system
use these to study glands and hormones
| Question | Answer |
|---|---|
| regulates metabolism, growth, reproduction and long-term homeostasis with glands and hormones | endocrine system |
| secretes substances needed by an organism | gland |
| discharge secretions into a duct | exocrine glands |
| discharge their secretions (hormones) into the blood | endocrine glands |
| chemicals given off by glands that have the ability to alter a cell's function by starting, speeding up, slowing down, or stopping reactions | hormones |
| a group of cells that contain receptor molecules that is specific to a particular hormone | target tissue |
| protein molecules on cells | receptor |
| structure in the brain that regulates the pituitary gland; acts as a bridge between the endocrine and nervous system | hypothalamus |
| master gland that controls other glands found in the brain | pituitary |
| stimulates the thyroid to release thyroxine | thyroid stimulating hormone |
| increases growth of bone and cartilage | growth hormone |
| stimulates the development of sperm and egg | follicle stimulating hormone |
| causes release of egg cells | luteinizing hormone |
| causes contraction of smooth muscle during childbirth | oxytocin |
| responsible for metabolism by secreting thyroxine; located in the neck | thyroid |
| causes the fight-or-flight response by releasing adrenalin (epinephrine) raising heartbeat, blood pressure and breathing; found on top of the kidneys | adrenal |
| produces insulin to lower blood sugar levels and glucagon to raise blood sugar levels | pancreas |
| failure to produce proper insulin to remove glucose from the blood | diabetes |
| sex organs; ovaries and testes | gonads |
| produces estrogen that regulates the development of the female reproductive system | ovaries |
| produces testosterone that regulates the development of the male reproductive system | testes |
| restoring homeostasis after events are triggered to reverse an event | negative feedback |
| body intensifies an activity until homeostasis is restored | positive feedback |
