What is the term used for chemical secretions of endocrine glands

What is a gland? A gland is an organ which produces and releases substances that perform a specific function in the body. There are two types of gland. Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream. These glands form part of the endocrine system and information on them is included in this website. There is another type of gland called an exocrine gland (e.g. sweat glands, lymph nodes). These are not considered part of the endocrine system as they do not produce hormones and they release their product through a duct. Information on these glands is not included on this website. Endocrine glands, such as the pancreas and thyroid gland, use the bloodstream to monitor the body’s internal environment and to communicate with each other through substances called hormones, which are released into the bloodstream. The adrenal glands are small structures attached to the top of each kidney. The human body has two adrenal glands that release chemicals called hormones into the bloodstream. These hormones affect many parts of the human body.

Therapy and Treatment Learning Objectives By the end of this section, you will be able to: • Identify the major glands of the endocrine system • Identify the hormones secreted by each gland • Describe each hormone’s role in regulating bodily functions The endocrine system consists of a series of glands that produce chemical substances known as hormones ( The major glands of the endocrine system are shown. Hormones are involved in regulating all sorts of bodily functions, and they are ultimately controlled through interactions between the hypothalamus (in the central nervous system) and the pituitary gland (in the endocrine system). Imbalances in hormones are related to a number of disorders. This section explores some of the major glands that make up the ...

Women often use hormone therapy to relieve hot flashes and other menopause symptoms — and new research suggests whether they choose pills, patches or creams might matter for their blood pressure hormone, organic substance hormone has been extended beyond the original definition of a General features Relationships between endocrine and neural regulation Hormonal regulation is closely related to that exerted by the The distinctions between neural and endocrine regulation, no longer as clear-cut as they once seemed to be, are further weakened by the fact that neurosecretory nerve endings are sometimes so close to their target cells that vascular transmission is not necessary. There is good evidence that hormonal regulation occurs by diffusion in plants and (although here the evidence is largely indirect) in lower animals (e.g., coelenterates), which lack a

Medical Dictionary for the Health Professions and Nursing © Farlex 2012 secretion The synthesis and release of chemical substances by cells or glands. Substances secreted include enzymes, hormones, lubricants, surfactants and neurotransmitters. Internal secretion is secretion into the bloodstream. External secretion may be into the intestinal canal or other organs or on to the skin. Compare Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 secretion • the process by which a useful substance produced in a cell is passed through the plasma membrane to the outside. • the substance itself. Secretions are usually produced by gland cells, but may be the results of cell destruction as in 1. The substance produced by a cell or organ (e.g. a gland). 2. Production by a cell or organ of a physiologically active substance. This flow out of a cell is driven by an osmotic pressure gradient across the membrane, which is created by active transport of one or more ion species from one side to the other.

Learning Objectives By the end of this section, you will be able to: • Distinguish similarities and differences between neural and hormonal communication • Identify the major organs of the endocrine system and their location in the body Communication within the human body involves the transmission of signals to control and coordinate actions in an effort to maintain homeostasis. There are two major organ systems responsible for providing these communication pathways: the nervous system and the endocrine system. The nervous system is primarily responsible for rapid communication throughout the body. As discussed in previous chapters, the nervous system utilizes two types of signals – electrical and chemical ( In contrast, the endocrine system relies on only a single method of communication: chemical signaling (Table 1). Hormones are the chemicals released by endocrine cells that regulate other cells in the body.   Hormones are transported primarily via the bloodstream throughout the body, where they bind to receptors on target cells, triggering a response. Because of this dependence on the cardiovascular system for transport, this type of communication is much slower than that observed for neural signaling.  As such, hormonal communication is usually associated with activities that go on for relatively long periods of time.
