QuestionAnswer
The Glenohumeral joint is triaxial... T or F T
This joint has a lot of mobility, but is relatively unstable Glenohumeral Joint
The shoulder can be broken down into 4 component parts or joints. S, A, G, S 1. Sternoclavicular (SC) Joint, 2. Acromioclavicular (AC)Joint, 3. Glenohumeral Joint, 4. Scapulothoracic Articulation.
Provides the shoulder girdle with its only direct attachment to the trunk Sternoclavicular joint
Plane‐shaped synovial joint with an articular disk sternoclavicular joint
Motions occur in three planes and accompany the motions of the shoulder girdle sternoclavicular joint
Connects the acromion process of the scapula with the lateral end of the clavicle Acromioclavicular Joint
It is a plane shaped synovial joint with three planes of motion Acromioclavicular joint, Motions are minimal but important to normal shoulder motion
Provides stability and allows the scapula to be suspended by the clavicle Coracoclavicular Ligament
Forms a protective arch over the head of the humerus, provides support to the head when an upward force is transmitted along the humerus Coracoacromial ligament
The scapula glides on the thorax and is attached to the thorax both by muscles, and through the clavicle to the sternum Scapulothoracic joint
Shoulder Girdle Motions (7) Protraction/Retraction, Elevation/Depression, Upward Rotation, Downward Rotation, Scapular Tilt
Glenohumeral motions MUST be accompanied by Scapular Motions
When there is flexion or abduction of the glenohumeral joint There must also be? upward rotation of the scapula
