Shoulder Complex Overview

A set of vocabulary flashcards covering the joints, kinematic principles, and stabilizers of the shoulder complex as outlined in the BPT notes.

Sternoclavicular Joint

One of the primary joints of the shoulder complex involving the articulation between the sternum and the clavicle.

Acromioclavicular Joint

A joint of the shoulder complex formed by the junction of the acromion process of the scapula and the clavicle.

Glenohumeral Joint

The multi-axial ball-and-socket joint of the shoulder complex articulating the humerus and the glenoid fossa.

Scapulothoracic Joint

A functional joint of the shoulder complex where the scapula moves over the posterior thoracic wall.

Osteokinematics

The study of the gross movements of bones at joints, such as flexion, extension, and abduction.

Arthrokinematics

The study of the small, involuntary movements that occur between the articular surfaces of joints, such as rolls, glides, and spins.

Kinetics

The study of the forces (internal and external) that act on the shoulder complex to produce motion.

Static Stabilizers

Passive structures that maintain joint integrity and stability, specifically the joint capsule, labrum, and ligaments.

Dynamic Stabilizers

Active structures that provide stability to the shoulder complex during movement, including the rotator cuff and scapular muscles.

Scapulohumeral Rhythm

The coordinated, kinematic relationship between the scapula and the humerus during shoulder elevation.
