Physiology of the Endocrine System:
In the Endocrine System, all physiogical processes are controlled by the body.
Hormones are chemical signals made by this system. They influence the activites of the cell by binding to membranes. Hormones are made in glands, which are all around the body.
Glands release hormones into the bloodstream. Such as, Exocrine glands. These glands secrete their products into the outer environment. Some of these glands are: sweat glands, salivary glands, mammary glands, stomach, liver, and pancreas. The Endocrine glands have only one function and that is to produce hormones. Some of these glands are: pituitary glands, thyroid glands, parathyroid glands, thymus glands, and adrenal glands.
Pituitary glands: in the middle of the brain--small endocrine organ that controls many functions in the body
Pineal glands: near the middle of the brain--produces serotonin derivative melatonin
Ovaries: female reproductive organ
Steroid hormones can cause changes in the cell by going through the cell membrane of the target cell. They can do this because they are fat-soluble. Steroid hormones are: any hormone affecting the development and growth of sex organs. Nonsteroid hormones are organic compounds that don't contain a steroid.
Prostaglandins: any group of cyclic fatty acids with no hormonelike effects.
The brain and hormones: The endocrine system works largely on neurons in the brain, which control the pituitary gland. The brain has receptors for many hormones. The hormones: the metabolic insulin, insulin-like growth factor, ghrelin, and leptin; are all controlled by the brain's receptors. The pituitary gland is referrred to as "the master gland" because it controls many of the activities in the body. It sends signals to different organs and glands in the body. The pituitary gland secretes hormones that act on the adrenal glands, thyroid glands, ovaries, testes.
