Anatomical terms of motion
The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved.Flexion and extension are examples of angular motions, in which two axes of a joint are brought closer together or moved further apart.The prefix hyper- is sometimes added to describe movement beyond the normal limits, such as in hypermobility, hyperflexion or hyperextension.[5] For example, if a part of the body such as a joint is overstretched or "bent backwards" because of exaggerated extension motion, then it can be described as hyperextended.When a joint can move forward and backward, such as the neck and trunk, flexion is movement in the anterior direction.When a joint can move forward and backward, such as the neck and trunk, extension is movement in the posterior direction.The knee, ankle, and wrist are exceptions, where the distal end has to move in the anterior direction for it to be called extension.[b] Abduction is a motion that pulls a structure or part away from the midline of the body, carried out by one or more abductor muscles.These terms are used to resolve confusion, as technically extension of the joint is dorsiflexion, which could be considered counter-intuitive as the motion reduces the angle between the foot and the leg.[30] These terms refer to flexion between the hand and the body's dorsal surface, which in anatomical position is considered the back of the arm; and flexion between the hand and the body's palmar surface, which in anatomical position is considered the anterior side of the arm.In the extremities, they are the rotation of the forearm or foot so that in the standard anatomical position the palm or sole is facing anteriorly when in supination and posteriorly when in pronation.Pronation at the forearm is a rotational movement where the hand and upper arm are turned so the thumbs point towards the body.
