Endocrine System
what I need to understand |
1. understand the functions on the endocrine system |
2. discuss: the role and function in the body including, how to define a hormone explain the process by which hormones bind to the receptor sites of specific tissues and explain three mechanisms that control the secretion of hormones |
3. The pituitary gland: describe relationship of the hypothalamus to the pituitary gland and describe location, regulation and hormones of the pituitary gland. |
4. distinguish between hormones, paracines and autocrines |
5. identify major endocrine glands and organs and other organs the produce hormones |
6. understand the importance of the endocrine system in maintaining homeostasis |
7. define homestasis |
between hormones autocrines and paracrines
hormones |
any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. |
autocrines |
local chemical messengers that act on the cell the secreted |
paracrine |
local chemical messengers that act on neighboring cells |
|
|
The pituitary gland
relationship between hypothalmus to the pituitary gland |
location of pituitary |
regulation of pituitary |
hormones in the pituitary |
endocrine glands
major endocrine glands |
major endocrine organs |
other organs that produce hormones |
endocrine system includes
Ductless glands Secrete hormones |
Widely distributed throughout the body |
Organs and tissues |
-pancreas, adipose tissue, Gonads (ovaries, testis), Kidney, thymus |
Endocrine glands |
-Thyroid, parathyroid, pineal, pituitary, adrenal gland |
|

functions of the Endocrine system
The functions of the endocrine system: The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. |
What is homeostasis
homeostasis |
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. |
hormones
Chemical messengers that influence or control activities of other tissues and organs Classification -Proteins (and protein- related substances) -Steroids (synthesized from Cholesterol) |
|
|
the role and function of hormones
Hormone |
chemical messenger that influences or controls the activities of other tissues and organs |
The process which binds hormones to specific tissues |
Three mechanisms that control secretion of hormones |
maintaining homeostasis
