Why non antigenic term is not included in the definition of hormone?
Answers
Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.
Explanation:
A hormone (from the Greek participle “ὁρμῶν”, "setting in motion") 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 behavior. Hormones have diverse chemical structures, mainly of three classes: eicosanoids, steroids, and amino acid/protein derivatives (amines, peptides, and proteins). The glands that secrete hormones comprise the endocrine signaling system. The term hormone is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signalling) or nearby cells (paracrine signalling).
