A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes). Instead, endocrine glands secrete their hormones directly into the surrounding extra cellular space.

Pituitary (also called Hypophysis) 1  Is a two-lobed organ that secretes nine major hormones.  Neurohypophysis – posterior lobe (neural tissue) receives, stores, and releases hormones (oxytocin and antidiuretic hormone) made in the hypothalamus and transported to the posterior pituitary via axons.

Anatomy of the adrenal glands. Adrenal glands, which are also called suprarenal glands, are small, triangular glands located on top of both kidneys. An adrenal gland is made of two parts--the outer region is called the adrenal cortex and the inner region is called the adrenal medulla.

The Thyroid gland is one of the largest endocrine glands in the body. It is positioned on the neck just below the Larynx and has two lobes with one on either side of the trachea. It is involved in the production of the hormones T3 (triiodothyronine) and T4 (thyroxine).

The adrenal cortex secretes hormones that have an effect on the body's metabolism, on chemicals in the blood, and on certain body characteristics. The adrenal cortex secretes corticosteroids and other hormones directly into the bloodstream. The hormones produced by the adrenal cortex include: Cortisol.

1 They include the thyroid hormones and the hormones of the adrenal medulla (epinephrine and norepinephrine). These hormones are water soluble.  Peptide Hormones. These hormones consist of chains of amino acids that vary in size from 3 amino acids (TRH) to 191 amino acids (GH).

A hormone is a chemical substance made and secreted by one cell that travels through the circulatory system or the extracellular fluid to affect the activities of cells in another part of the body or another nearby cell.

Introduction To The Endocrine System[edit] The endocrine system is a control system of ductless glands that secrete hormones within specific organs. Hormones act as messengers, and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them.

The endocrine system is made up of ductless glands called endocrine glands that secrete chemical messengers called hormones into the bloodstream or in the extracellular fluid.
