adduction meaning medical
Adduction refers to a motion that pulls a structure or part toward the midline of the body, or towards the midline of a limb. In the case of fingers and toes, it refers to bringing the digits together, towards the centerline of the hand or foot. Adduction of the wrist is also called ulnar deviation. Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the joints. Word Origin and History for abduction Expand. n. 1620s, a leading away, from Latin abductionem (nominative abductio), noun of action from past participle stem of abducere to lead away, take away (often by force), from ab- away (see ab-) + ducere to lead (see duke (n.)).

Abduction is sometimes used to mean just the generation of hypotheses to explain observations or conclusionsm, but the former definition is more common both in philosophy and computing. Closing arms to the chest or bringing knees together are other examples of adduction. Adduction of the wrist, moving a hand toward the body at the wrist when that arm is at the person’s side, is also called ulnar deviation. Any muscle that creates this type of motion is called an adductor. In medicine and biomechanics, movements of limbs and other body parts toward or away from the center line of the body (a line that runs up and down the center of the human body) are termed adduction and abduction, respectively. Rotational motion may occur at other joints, for example the shoulder, and are described as internal or external. Other terms, such as elevation and depression, refer to movement above or below the horizontal plane. Many anatomical terms derive from Latin terms with the same meaning.

He tells all to Anna Nemtsova, including the story of his abduction by aliens. See also: List of abductors of the human body and List of adductors of the human body. Abduction and adduction refer to motions that move a structure away from or towards the centre of the body. The centre of the body is defined as the midsagittal plane. These terms come from the Latin words with the same meaning. Adduction is the movement of a body part toward the body’s midline. So, if a person has their arms straight out at the shoulders and brings them down to their sides, it is adduction. For fingers or toes, adduction brings the digits toward the center of the hand or foot.
