Endocrine System & HormonalFunction

Hormones are the chemical messengers of our body.

Endocrine Hormones are secreted into the circulatory system & then transported by the blood to all areas of the body.

Each Hormone has effect only on the specific target cells that uniquely react to the presence of that hormone!

Target cells contain receptors that respond to specific hormones being transported throughout the body by the circulatory system.
There are receptors in each of our cells.
- Each of these receptors responds to specific a hormone's unique amino acid chain or pattern.
Once the hormone is bound to the receptor cell, a chain of genetically predetermined biochemical events within the target cell occur.

Examples of hormones referenced in day to day conversations.

Estrogen: The hormone of the female reproductive system & the hormone involved in menopause.
Testosterone: Testosterone is the most important hormone in the male body.
Insulin: The hormone related to sugar metabolism & diabetes
Seratonin: Low levels of this hormone is related to depression & the Prozac family of psychotropic medications.
Endorphins: The source of the runners high.

The hormones that are produced by our endocrine system are chemical messengers. Hormones are produced by the glands of our endocrine system.
- Endorphins are believed to produce four key effects on the body: they enhance the immune system, they relieve pain, they reduce stress, and postpone the aging process.
& of course, HGH. Human Growth Hormone.

Hormones are secreted by the glands of the endocrine system

Hormones are used at the cellar level for communication between body systems

Hormones directly effect function, efficiency and rejuvenation.

Our growth, mood, digestion, respiration, sense of thirst and hunger, sexual functions, fat metabolism and most other bodily functions are all triggered by hormones.
The amount of hormone released or secreted by the endocrine glands is determined by the bodies need for that particular hormone at a given time.
- As we age our bodies requirement for hormones is not met because of declining hormonal production.

- The degree to which the target cell responds to the hormone depends on the number of target cells, genetics and the concentration of the hormone.

The amino acid structure of the hormone is the key and the receptor is a lock.
- In order for the key, hormone, to fit the lock, receptor, the hormone-receptor complex must be an exact match.
It for any reason this lock and key do not fit, cellular binding is disrupted, hormonal signals are interrupted and the communication is not complete.
- In effect the "chemical / hormonal" phone lines are down.

Type II diabetes is related to insulin receptor function decline.
