The endocrine system helps the body grow, develop and maintain homeostasis. The endocrine system makes chemicals called hormones that act to maintain homeostasis. Hormones are made by organs known as glands.
3
As hormones move through the body they will be in contact with many cells, however they will only interact with specific cells that have the proper receptor. Cells that have the correct receptors are called target cells.
4
There are two categories of hormones: › Steroid hormones › Non-steroid hormones ALL steroid hormones are made from cholesterol, which is a lipid.
8
The hypothalamus acts as a connection between the CNS and the endocrine system. The hypothalamus is located at the base of the brain.
9
As part of the CNS the hypothalamus receives, interprets, and sorts information from the sensory organs. As part of the endocrine system, the hypothalamus produces releasing hormones.
10
The hypothalamus is known as the master control center of the endocrine system. › Its endocrine signals directly control the pituitary gland which secretes hormones that will influence body functions.
11
Hypothalamus releases TRH in response to cold exposure, which stimulates the pituitary to release TSH. TSH is called thyroid- stimulating hormone. Thyroid is stimulated to release thyroxine. Thyroxine is released into the blood where it increases the metabolic rate of body cells, thereby warming the body. Warmth of body ends stimulation of hypothalamus, halting the cycle. See how the hypothalamus controls EVERYTHING ?
12
The pituitary gland is actually an extension of the hypothalamus, which consists of an anterior and posterior lobe.
15
The thyroid gland helps to regulate development and metabolism. The thyroid and parathyroid gland maintain calcium homeostasis by regulating the hormone calcitonin.
18
The adrenal glands, which are located on top of the kidneys, produce hormones that enable the body to respond to stress.
