APSM Biology 3.4
APSM CA Biology 3.4 Endocrine System
| Term | Definition |
|---|---|
| Adrenal cortex | outer layer of adrenal gland produces steroid hormones |
| Adrenal gland | endocrine gland located on top of kidney, produces epinephrine and steroid hormones |
| Adrenal medulla | makes epinephrine (adrenaline) which regulates the metabolism |
| Adrenaline | Hormone produced by the adrenal gland |
| Calcitonin | hormone produced in thyroid that help with calcium regulation |
| Cyclic AMP | messenger that transfers effects of certain hormones into cells |
| Diabetes | disease where sugar accumulates in the bloodstream instead of being stored by glycogen, caused by problems with producing or responding to insulin |
| Dwarfism | lack of height caused by not enough growth hormone |
| Endocrine glands | Ductless glands |
| Epinephrine | hormone produced by adrenal glands that prepare the body to respond to emergency situations |
| Estrogen | primary female reproductive hormones |
| Exocrine glands | gland that secretes products to the outside of the body |
| Gigantism | production of too much growth hormone causing excessive height |
| Glucagon | pancreatic hormone that signals the liver to convert glycogen to glucose & release the glucose into the bloodstream |
| Hormones | Chemical messengers produced by endocrine glands |
| Insulin | pancreatic hormone that signal the liver & muscle to remove glucose from the blood and store it as glycogen |
| Islets of Langerhans | clumps of endocrine glands in the pancreas that produce insulin and glucagon |
| Non-steroidal Hormones | hormones that sit on the top of the cell and send cyclic AMP inside to cause cellular change |
| Ovary | female gonad that produces estrogen and releases eggs |
| Pancreas | organ that produces pancreatic juice and contains the islets of Langerhans |
| Parathyroid | small endocrine glands in the neck of humans that produces and secretes hormones to regulate the amount of calcium in the blood and bones |
| Pituitary gland | Controls the other endocrine glands |
| Steroidal Hormones | hormones that can go into a cell to change the chemistry |
| Testes | male gonad that produces testosterone |
| Testosterone | primary male reproductive hormone, causes increased muscle & bone mass, growth |
| Thyroid | endocrine gland located in neck, regulates rate of chemical activity in the cells |
| Thyroxine | thyroid hormone that regulate general activities related to metabolism |
| Type I Diabetes | autoimmune disease where the immune system destroys the pancreatic cells that produce insulin |
| Type II Diabetes | form of diabetes characterized by insulin resistance; occurs primarily as a result of obesity and lack of exercise |
