Amino acids with modified groups norepinephrine's carboxyl group is replaced with a benzene ring. Peptide Hormone Short chains of linked amino acids. Protein Hormone Long chains of linked amino acids. Steroid Hormone Derived from the lipid cholesterol Maintaining homeostasis within the body requires the coordination of many different systems and organs. Communication between neighboring cells, and between cells and tissues in distant parts of the body, occurs through the release of chemicals called hormones. Hormones are released into body fluids usually blood that carry these chemicals to their target cells. At the target cells, which are cells that have a receptor for a signal or ligand from a signal cell, the hormones elicit a response. Endocrine System Endocrine System

Stimulate development of female secondary sex characteristics and prepare the body for childbirth Types of Hormones The hormones of the human body can be divided into two major groups on the basis of their chemical structure. Hormones derived from amino acids include amines, peptides, and proteins. Those derived from lipids include steroids Figure 1. Amine Hormones Hormones derived from the modification of amino acids are referred to as amine hormones. Amine hormones are synthesized from the amino acids tryptophan or tyrosine. An example of a hormone derived from tryptophan is melatonin, which is secreted by the pineal gland and helps regulate circadian rhythm. Tyrosine derivatives include the metabolism-regulating thyroid hormones, as well as the catecholamines, such as epinephrine, norepinephrine, and dopamine. Epinephrine and norepinephrine are secreted by the adrenal medulla and play a role in the fight-or-flight response, whereas dopamine is secreted by the hypothalamus and inhibits the release of certain anterior pituitary hormones. Endocrine System

Click 'Back to Intro' to return to the beginning of this section. Anatomy of the Endocrine System The endocrine system is a complex network of glands and organs.

Neural and Endocrine Signaling

The following are key parts of the endocrine system: Click Image to Enlarge Hypothalamus. The hypothalamus is located at the base of the brain. It makes hormones that control hormones released in the pituitary gland. The hypothalamus controls water balance, sleep, temperature, appetite, mood and reproductive behaviors, and blood pressure.

Pineal gland. This gland is located Endocrine System the middle of the brain. It makes the Endocrine System melatonin. This hormone helps your body know when it's time to sleep.

Introduction:

This hormone also regulates the timing of other functions throughout the body, such as when puberty starts. Pituitary gland.

Endocrine System

This gland is located below the brain. It is often as small as a pea. But it controls many functions of the other endocrine glands. Thyroid and parathyroid. These glands are located in front of the neck, below the voice box larynx. The Endocrine System Endorine a key role in the body's metabolism. The parathyroid helps regulate the body's calcium balance and bone strength. Adrenal gland.

Structures of the Endocrine System

An adrenal gland http://rmt.edu.pk/nv/custom/evaluating-the-limitations-of-market-research/civil-war-immigration-analysis.php located on top of each kidney. Like many glands, these work together with Endocrine System hypothalamus and pituitary gland. The adrenal glands make and release corticosteroid hormones and adrenaline epinephrine. These maintain blood pressure and regulate metabolism. This organ is located across the back of the belly abdomenbehind Systtem stomach. It plays a role in digestion and hormone production. Hormones made by the pancreas include insulin and glucagon. These regulate blood sugar levels. A woman's ovaries are located on both sides of the uterus, below the opening of Endocrine System fallopian tubes.

The ovaries contain the egg cells needed for reproduction. They also make estrogen and progesterone. A man's testes are located in a pouch that hangs suspended outside the male body. The testes make testosterone and sperm.
