Many muscles contribute to these movements: The psoas is the primary hip flexor, assisted by the iliacus. The pectineus, the adductors longus, brevis, and magnus, as well as the tensor fasciae latae are also involved in flexion. The gluteus maximus is the main hip extensor, but the inferior portion of the adductor magnus also plays a role.
In 33% of people a supernumerary muscle is found between the adductor brevis and adductor minimus. When present, this muscle originates from the upper part of the inferior ramus of the pubis from where it runs downwards and laterally. In half of cases, it inserts into the anterior surface of the insertion aponeurosis of the adductor minimus.
This—and any movement that involves pulling one or both of your arms or legs in towards the center of your body—is adduction, Hammond explains. While your hip abductor muscles, for example ...
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
Adduction is a motion that pulls a structure or part towards the midline of the body, or towards the midline of a limb, carried out by one or more adductor muscles. In the case of fingers and toes, it is bringing the digits together, towards the centerline of the hand or foot.
The pair of muscles are commonly known as "lats", especially among bodybuilders. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction (or horizontal extension), [1] flexion from an extended position, and (medial) internal rotation of the shoulder joint.
Abduction and adduction of the shoulder (frontal plane). Abduction is carried out by the deltoid and the supraspinatus in the first 90 degrees. From 90-180 degrees it is the trapezius and the serratus anterior. Adduction is carried out by the pectoralis major, latissimus dorsi, teres major and the subscapularis. Horizontal abduction and ...
