Exam 2 - Upper Limb - General Flashcards
What type of joint is the glenohumeral joint?
Synovial joint - ball and socket joint
What is the glenoid labrum
Rib of fibrocartilage attached to glenoid cavity that deepens the articular surface
What are the ligaments that surround the joint capsule of the glenohumeral joint?
Anteriorly: superior, middle, inferior glenohumeral ligaments
Superiorly: coracohumeral ligament
What are two of the functions of the synovial membrane that lines the capsule of the glenohumeral joint?
- Forms a tendon sheath around the tendon of the biceps brachii
- Communicates with the subtendinous bursa of subscapularis
Ligament that attaches from coracoid process to acromion of scapula
coracoacromial ligament
Ligament that prevents superior dislocation of humerus
coracoacromial ligament
What are the three bursas associated with the glenohumeral joint?
- Subtendinous bursa of the subscapularis - anterior
- Subacromial bursa - superior
- Subdeltoid bursa - lateral
Subtendinous bursa of subscapularis
- Superior bursa of glenohumeral joint
- between the subscapularis tendon and neck of scapula
- communicates with the synovial cavity
Subacromial bursa
- superior
- under coracoacromial ligament
- above supraspinatus tendon and glenohumeral joint capsule
Subdeltoid bursa
- lateral
- deep to deltoid muscle
- above subscapularis tendon
