Anatomy and Functions of the Glenohumeral Joint [Part 2]

The video tutorial provides an in-depth look at the glenohumeral joint, focusing on its anatomy and the intrinsic ligaments that stabilize it. It covers the transverse humeral ligament, coracohumeral ligament, and the redundant capsule, explaining their roles in joint stability. The tutorial also discusses the glenohumeral ligaments, coracoacromial ligament, and the rotator interval, highlighting their importance in maintaining shoulder stability and function.

What feature is absent in the anterior view of the scapula?

• Coracoid process

• Scapular spine

• Subscapular fossa

• Acromion process

Which ligament spans between the greater and lesser tubercles of the humerus?

• Coracoacromial ligament

• Coracohumeral ligament

• Transverse humeral ligament

• Superior glenohumeral ligament

What is the primary function of the superior, middle, and inferior glenohumeral ligaments?

• Connect the clavicle to the scapula

• Strengthen the anterior capsule

• Limit upward translation of the humerus

• Strengthen the posterior capsule

Where does the coracohumeral ligament extend from and to?

• From the coracoid process to the anatomical neck of the humerus

• From the acromion to the clavicle

• From the scapular spine to the humerus

• From the glenoid fossa to the humerus

Which ligament completes the coracoacromial arch?

• Coracoacromial ligament

• Superior glenohumeral ligament

• Coracohumeral ligament

• Transverse humeral ligament

What is the function of the coracoacromial arch?

• To connect the clavicle to the scapula

• To limit upward translation of the humerus

• To stabilize the AC joint

• To deepen the glenoid fossa

What is the role of the glenoid labrum?

• To stabilize the AC joint

• To deepen the glenoid fossa

• To connect the humerus to the scapula

• To limit the range of motion

Which muscle's tendon passes through the subacromial space?

• Supraspinatus

• Subscapularis

• Infraspinatus

• Teres minor

What is the rotator interval?

• A ligament connecting the clavicle to the scapula

• A tendon of the biceps brachii

• A part of the glenoid labrum

• A space between the supraspinatus and subscapularis

What happens if the rotator interval is damaged?

• Improved range of motion

• Enhanced muscle strength

• Decreased shoulder stability

• Increased shoulder stability
