what are the three ligaments that support the shoulder joint?

lateral ligament
transverse humeral ligament
coracohumeral ligament
acromiohumeral ligament
glenohumeral ligaments

Explanation:

Identify the target joint and its anatomical structures

The question asks for three ligaments supporting the shoulder joint (glenohumeral joint).

Evaluate the options using anatomical knowledge

Using the Glenohumeral Joint and Shoulder Stabilizers knowledge points:

• Lateral ligament: Typically associated with the temporomandibular joint or knee (LCL), not the shoulder.
• Transverse humeral ligament: A narrow sheet running between the greater and lesser tubercles of the humerus, holding the long head of the biceps brachii tendon in place. It supports the shoulder joint complex.
• Coracohumeral ligament: A broad ligament strengthening the upper part of the articular capsule, extending from the coracoid process of the scapula to the humerus.
• Acromiohumeral ligament: This is not a standard anatomical ligament (the coracoacromial ligament exists, but not acromiohumeral).
• Glenohumeral ligaments: Three fibrous bands (superior, middle, inferior) that reinforce the anterior part of the articular capsule.

Select the three correct supporting ligaments

The three correct supporting ligaments of the glenohumeral joint from the list are:

1. Transverse humeral ligament
2. Coracohumeral ligament
3. Glenohumeral ligaments

Answer:

• Lateral ligament
• Transverse humeral ligament (Correct answer)
• Coracohumeral ligament (Correct answer)
• Acromiohumeral ligament
• Glenohumeral ligaments (Correct answer)
