endocrine system Cheat Sheet (DRAFT) by

anatomy and physiology

This is a draft cheat sheet. It is a work in progress and is not finished yet.

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

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.
local chemical messengers that act on the cell the secreted
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

the tendency toward a relatively stable equili­brium between interd­epe­ndent elements, especially as maintained by physio­logical processes.


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

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
