VENOMOTOR Meaning and
Definition
-
Venomotor refers to an adjective used to describe something related to venous circulation or the movement of blood within the veins. Specifically, the term is associated with mechanisms or substances that influence or regulate the contraction and relaxation of the smooth muscles found in the walls of veins.
In the field of physiology, venomotor tone refers to the level of vascular activity and the degree of constriction or relaxation exhibited by the venous system. The venomotor tone is primarily regulated by the autonomic nervous system, particularly the sympathetic division. The sympathetic nerves release certain chemical substances known as neurotransmitters, which act on the smooth muscles of the veins, causing them to contract or relax. This alteration in the venomotor tone helps to regulate blood flow, facilitating the return of deoxygenated blood towards the heart and maintaining proper circulation.
Venomotor mechanisms play a crucial role in various physiological processes, including blood volume regulation, venous return, and blood pressure control. Dysfunction of these mechanisms can lead to venous insufficiency, varicose veins, or other venous disorders.
In summary, venomotor refers to the factors, substances, or processes that influence the contraction and relaxation of the smooth muscles in veins, contributing to the regulation of venous circulation in the body.

Etymology of VENOMOTOR
The word "venomotor" is derived from two key elements: "veno-" and "-motor".
The prefix "veno-" comes from the Latin word "venum", meaning "poison" or "venom". It is commonly used in scientific and medical contexts to refer to substances or processes related to venom.
The suffix "-motor" originates from the Latin word "motor", meaning "mover" or "driver". It is frequently used to connote something related to movement or functioning.
Therefore, when these two elements are combined, "venomotor" refers to something that is involved in the movement or control of venom. It is typically used to describe anatomical structures or physiological mechanisms that aid in the distribution or pumping of venom within animals.
