Definition: Adduction is a term used in anatomy to describe the movement of a muscle between its two ends, which are typically considered as being on opposite sides. It's also known as extension or extension contraction. A muscle that moves from one end to the other by extending itself into the opposing side is known as an adductor. If the muscle has been addeducted at the origin (the point where it joins its tendon), it is called a lateral adductor. If the muscle is addeducted in a manner such that it does not extend all the way across to the opposite side, it is known as an internal adductor. The word 'adduction' comes from the Greek word 'adducere', which means to adduce or to elevate. It was originally used by Roman surgeons and was often used to describe the movement of the muscles around the joint between the shoulder and elbow. The term has been adapted throughout history in various ways, but it is still used today to describe a muscle contraction that allows for the extension of an external rotation. The specific definition can vary depending on context, so it's important to consult medical or physical therapist guidance if you are unsure about the proper action or technique of addingucting muscles.
