Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
Unsurprisingly, muscles that help your body perform abduction movements are called abductors. For your legs, for instance, "the abductors are key contributors to stabilizing the hips," Hammond says.
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. In the case of fingers and toes, it is spreading the digits apart, away from the centerline of the hand or foot. [ 15 ]
Superior rectus muscle; Inferior rectus muscle; Medial rectus muscle; jaw (muscles of mastication, the closing of the jaw is adduction): masseter; pterygoid muscles (lateral and medial) temporalis; vocal folds. Lateral cricoarytenoid muscle
Muscles in the Lateral compartment of leg also weakly participate, namely the Fibularis longus and Fibularis brevis muscles. Those in the lateral compartment only have weak participation in plantar flexion though. The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The gluteal muscles can be classified into two main groups: The superficial gluteal muscles are responsible for extension and abduction of the hip as well as stabilizing and maintaining the balance of the pelvis during the gait cycle. Deep gluteal muscles control external rotation of the extended hip and abduction of the flexed hip. [2]
Three antagonistic pairs of muscles control eye movement: the lateral and medial recti muscles, the superior and inferior recti muscles, and the superior and inferior oblique muscles. These muscles are responsible for movement of the eye along three different axes: horizontal, either toward the nose (adduction) or away from the nose (abduction ...
