Shoulder Joint Anatomy and Function

The video provides a comprehensive overview of the shoulder joint, detailing its structure, ligaments, relations, blood supply, movements, and associated muscles. It also covers clinical conditions like dislocation, shoulder tip pain, and frozen shoulder, emphasizing the joint's mobility and stability.

What type of joint is the shoulder joint?

• Hinge joint

• Ball and socket joint

• Saddle joint

• Pivot joint

Which structure is NOT involved in maintaining the stability of the shoulder joint?

• Coracoacromial arch

• Muscular tenderness cuff

• Glenoid labrum

• Radial collateral ligament

Which ligament is known for being very loose and allowing free movement in the shoulder joint?

• Coracohumeral ligament

• Transverse humeral ligament

• Capsular ligament

• Glenoid labrum

What is the function of the transverse humeral ligament?

• It deepens the glenoid cavity

• It prevents upward displacement of the humerus

• It bridges the bicipital groove

• It strengthens the capsule

Which muscle is NOT related to the shoulder joint superiorly?

• Subacromial bursa

• Infraspinatus

• Deltoid

• Supraspinatus

Which nerve is NOT involved in the nerve supply to the shoulder joint?

• Musculocutaneous nerve

• Suprascapular nerve

• Axillary nerve

• Radial nerve

During flexion of the shoulder joint, which direction does the arm move?

• Backwards and laterally

• Forwards and medially

• Downwards and laterally

• Upwards and medially

Which muscle is NOT primarily involved in the abduction movement of the shoulder joint?

• Latissimus dorsi

• Serratus anterior

• Deltoid

• Supraspinatus

What is a common cause of shoulder tip pain?

• Tear in the rotator cuff

• Dislocation of the shoulder

• Irritation of the diaphragm

• Frozen shoulder

What condition is characterized by the adhesion of synovial membrane layers in the shoulder?

• Dislocation

• Shoulder tip pain

• Frozen shoulder

• Bursitis
