The adductor longus is a prime adductor and medial rotator of the femur. It is also an assistant mover for flexion at the hip.

Therefore the antagonist muscles are the abductors (apposing adduction), the lateral rotators (apposing medial rotation) and the extensors (apposing flexion).

Primary Abductors: Gluteus Medius and Gluteus Minimus

Assistant Abductors: Tensor Fasciae Latter, Sartorius

Primary Lateral Rotators: Glutteus Maximus, Deep Later Rotator group

Assistant Lateral Rotators: Sartorius, Iliopsoas

Primary Extensors: Hamstrings, Gluteus Maximus

Assistant Extensors: Adductor Magnus (upper fibres)

The antagonist in shoulder extension is the shoulder flexors, which are the muscles responsible for flexing or bending the shoulder joint. They work in opposition to the shoulder extensors, which are the primary movers in shoulder extension.

Extension of the shoulder joint

Agonist = Posterior Deltoid

Antagonist = Latissimus Dorsi

If a prime mover produces flexion its antagonist will be?

If a prime mover produces flexion, its antagonist will be the muscle responsible for producing extension at the same joint. They work in opposition to each other to create movement and stabilize the joint.


What is The muscle responsible for extension of the forearm?

Extension of the forearm at the elbow joint is achieved almost entirely by the triceps brachii but extension of the arm, which actually takes place at the shoulder joint, is achieved by muscles on the back, such as the latissimus dorsi.


What joint connects the arm and shoulder?

The shoulder joint connects the arm to the shoulder. It is a ball-and-socket joint that allows for a wide range of motion, such as flexion, extension, abduction, adduction, and rotation of the arm.


Turbulate the difference between shoulder and elbow joints?

1. Shoulder joint is a synovial(ball and socket) joint. Whereas Elbow is a synovial(hinge) joint 2.Shoulder posses 3 degrees of freedom i.e Flexion, extension, abduction, adduction, medial and lateral rotations. Elbow have 1 degrees of freedom i.e flexion and extension 3.Difference of special structures i.e bursae 4.Shoulder is highly mobile than elbow


What muscles are the antagonist in shoulder circumduction?

The muscles that are involved in the circumduction of the shoulder joint are the pectoralis major, deltoid, supraspinatus, long head of triceps, biceps brachii, subscapularis, infraspinatus, coracobrachialis, teres major and minor and the latissimus dorsi.
