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)
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.
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.
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.
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
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.

The latissimus dorsi muscle is responsible for adducting the shoulder and causing extension of the shoulder joint. It is a large triangular muscle located in the back that helps with various movements of the shoulder and arm.
Shoulder adductors. Abduction means moving away from the median plane of the body and adduction means moving towards the median plane of the body.
