Five Facts About The Endocrine System
1. The endocrine system sends signals throughout the body, much like the nervous system, but unlike the immediate responses triggered by the nervous system, the effects can take a few hours or weeks.
2. The endocrine system is a group of small but immensely important organs that regulate metabolism, growth, tissue functioning, puberty, development and moods. These functions are performed via the release of hormones, which are extra-cellular signaling molecules that transmit information and instructions from a set of cells to another. The three most important endocrine glands are the pituitary, adrenal and thyroid. Almost every organ and cell in the body is affected by the endocrine system.
3. Endocrine glands are vascular and generally do not have ducts, using intracellular vacuoles, or granules, to store hormones. They differ from, exocrine glands — salivary glands, sweat glands and glands within the gastrointestinal tract — which have ducts or a hollow lumen.
4. The hormones (which are often called chemical messengers) that are released by glands in endocrine system are very crucial to regulating different systems of our body including our mood and growth. There are more than 30 major hormones which are secreted by glands in endocrine system.
5. A group of glands that signal each other in sequence are usually referred to as an axis. One example is the hypothalamic-pituitary-adrenal axis, which coordinates interactions among the hypothalamus, the pituitary gland and the adrenal, also called "suprarenal" glands, which are small, conical organs on top of the kidneys.
