Study Notes
Shoulder Joint Structure
- The scapula (specifically, the glenoid cavity) articulates with the head of the humerus in the shoulder joint.
Joint Type and Characteristics
- The shoulder joint, also known as the glenohumeral joint, is a synovial ball-and-socket joint.
Fibrous Capsule Attachment
- The fibrous capsule of the shoulder joint attaches to the margins of the glenoid cavity and the anatomical neck of the humerus.
Biceps Brachii and Joint Cavity
- The synovial tendon sheath encloses the long head of the biceps brachii within the shoulder joint cavity.
Articular Surfaces
- The articular surfaces within the shoulder joint are covered by hyaline cartilage.
