what are the four bursae of the shoulder joint?

subcoracoid
subscapular
subclavian
olecranal
subdeltoid
subacromial

Explanation:

Identify the target joint and structures

The question asks for the four major bursae associated with the shoulder (glenohumeral) joint. Bursae are fluid-filled sacs that reduce friction between moving parts in Synovial Structures.

Evaluate each option based on anatomical location

• Subcoracoid bursa: Located anterior to the scapula, deep to the coracoid process. It is one of the four primary shoulder bursae.
• Subscapular bursa: Located between the subscapularis tendon and the neck of the scapula, communicating with the joint cavity. It is a primary shoulder bursa.
• Subclavian bursa: There is no major bursa of this name associated with the shoulder joint.
• Olecranal bursa: Located at the elbow (posterior aspect of the olecranon process), not the shoulder.
• Subdeltoid bursa: Located deep to the deltoid muscle, often continuous with the subacromial bursa. It is a primary shoulder bursa.
• Subacromial bursa: Located inferior to the acromion process and superior to the supraspinatus tendon. It is a primary shoulder bursa.

Select the correct four bursae

The four primary bursae of the shoulder joint are the subcoracoid, subscapular, subdeltoid, and subacromial bursae.

Answer:

• Subcoracoid (Correct answer)
• Subscapular (Correct answer)
• Subclavian
• Olecranal
• Subdeltoid (Correct answer)
