Definition
| the dynamic state of equilibrium or balance of the internal environment of the body; static state- ex. body temp- 98.6 degrees F; a little higher or a little lower is okay; not a static state has a dynamic equilibrium to it; however too far away would be a disease or disorder-too much away results in death; important for regulating blood sugar |

Definition
| what is the main function of the endocrine system? |
|
|
Term
1. nervous system
2. endocrine system |
|
Definition
| communication within the body is essential for homeostasis and is accomplished by what two systems? |
|
|
Term
|
Definition
| nuerons communicate by sending nerve impulses along axons; at the end of axons (axon terminals), neurotransmitters (mediator molecules) are released |
|
|
Term
|
Definition
| hormones (mediator molecules) are produced by endocrine glands, secreted into surround tissue fluid, and then transported to target cells (those that have the receptors for those hormones) primarily via the blood stream |
|
|
Term
|
Definition
| secrete onto a surface; either directly or through a duct |
|
|
Term
|
Definition
| secrete internally to tissue fluid; ductless glands; utilize cardiovascular system for distribution |
|
|
Term
|
Definition
| an endocrine gland--produces thyroxin; found in neck on either side of the trachea |
|
|
Term
| thyroxin (secreted by the thyroid gland) |
|
Definition
| this hormone increases protein synthesis and breakdown of fats and increases use of glucose which breaks down to ATP; accelerate body growth, produce additional body heat; INCREASES BODY METABOLISM |
|
|
Term
1. pituitary gland
2. thyroid gland
3. parathyroid gland
4. adrenal gland
5. pineal gland |
|
Definition
| what are 5 exclusive endocrine glands? |
|
|
Term
|
Definition
| "master gland" for endocrine system; can synthesize and secrete 7 different hormones; along with the hypothalamus, it regulates all aspects of growth, homeostasis, development, metabolism; its hormones have a lot of influence on the body's glands like the thyroid |
|
|
Term
|
Definition
| found on the posterior surface of thyroid |
|
|
Term
|
Definition
| aka suprarenal glands; found superior to kidneys |
|
|
Term
|
Definition
| this endocrine gland is part of the epithalamus |
|
|
Term
1. hypothalamus
2. thymus
3. pancreas
4. ovaries
5. testes
6. kidneys
7. stomach
8. liver
9. small intestine
10. skin
11. heart
12. adipose tissue
13. placenta |
|
Definition
| what are 13 organs that are not exclusively an endocrine gland but has tissues that secrete hormones? |
|
|
Term
|
Definition
| command center for the endocrine system; part of diencephalon; major link between nervous system and endocrine system; vital for maintaining homeostasis; important regulatory center for nervous system and crucial for endocrine which can produce 9 different hormones; connected to pituitary gland through the infundibulum; many of the hormones secreted here will influence the pituitary gland |
|
|
Term
| example of homeostasis in endocrine system |
|
Definition
| eat a bunch of donuts-pancreas secretes insulin-liver takes up some glucose and stores as glycogen and other cells take glucose; your working out-pancreas release glucagon-goes to liver where it is broken down and it releases glucose to the blood |
