Atrial natriuretic peptide Atrial natriuretic peptide (ANP) is a peptide hormone which reduces an expanded extracellular fluid (ECF) volume by increasing renal sodium excretion. ANP is synthesized, and secreted by cardiac muscle cells in the walls of the atria in the heart.

ANP atrial natriuretic peptide (ANP), a hormone involved in natriuresis and the regulation of renal and cardiovascular homeostasis. It is synthesized as a prohormone in the granules of the myocytes of the atrium and is released into the circulation in response to atrial dilation or increased intravascular fluid volume.trial natriuretic peptide (ANP), a hormone involved in natriuresis and the regulation of renal and cardiovascular homeostasis.

Medical Definition of Hormone Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. Many hormones are secreted by special glands, such as thyroid hormone produced by the thyroid gland.Hormones are essential for every activity of life, including the processes of digestion, metabolism, growth, reproduction, and mood control.ormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. Many hormones are secreted by special glands, such as thyroid hormone produced by the thyroid gland.

The Definition of the Protein Hormone Protein-based hormones, more commonly called peptide hormones, are made up of amino acids, which are the structural building blocks of all proteins, including the proteins you eat. Peptide hormones tend to be globular, meaning that they have a ball-like shape.

Hormone Amino acid–based hormones (amines and peptide or protein hormones) are water-soluble and act on the surface of target cells via second messengers; steroid hormones, being lipid-soluble, move through the plasma membranes of target cells (both cytoplasmic and nuclear) to act within their nuclei. Hormone secretion may occur in many tissues.

Hormone A hormone is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour. Hormones have diverse chemical structures, mainly of 3 classes: eicosanoids, steroids, and amino acid/protein derivatives. The glands that secrete hormones comprise the endocrine signaling system. The term hormone is sometimes extended to include chemicals produced by cells that affect

Hormone A hormone (from Greek ὁρμή, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.he rate of hormone biosynthesis and secretion is often regulated by a homeostatic negative feedback control mechanism. Such a mechanism depends on factors that influence the metabolism and excretion of hormones.

Peptide Hormones Parathyroid hormone (PTH) is synthesized and secreted by chief cells of the parathyroid glands in response to systemic Ca 2+ levels. There are four parathyroid glands that lie adjacent to the thyroid gland and consist of two superior glands and two inferior glands.he regulatory peptides synthesized by the gut include hormones, peptide neurotransmitters and growth factors. Indeed, several hormones and neurotransmitters first identified in the central nervous system and other endocrine organs have subsequently been found in endocrine cells and/or neurons of the gut.

Growth hormone Growth hormone (GH), also known as somatotropin (or as human growth hormone [hGH or HGH] in its human form), is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. It is a type of mitogen which is specific only to certain kinds of cells.
