What JOINTS makes up the Shoulder Complex?
Sternoclavicular Joint
Acromioclavicular Joint
Glenohumeral Joint
Define Shoulder Girdle.
A term used to describe the action of the scapula, clavicle and sternum.
What are the LANDMARKS of the Scapula?
Superior Angle Inferior Angle Medial Border Axillary Border Spine of the Scapula Acromion Process Glenoid Fossa Coracoid Process
What does the Acromioclavicular Joint connect?
Connects the acromion process with the lateral clavicle.
What does the Sternoclavicular Joint connect?
The Medial Clavicle to the Sternum.
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint FLEXES?
Upward Rotation/Protraction
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint EXTENDS?
Downward Rotation, Retraction
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint HYPEREXTENDS?
Scapular Tilt
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint ABDUCTS?
Downward Rotation
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint ADDUCTS?
Upward rotation
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint MEDIAL ROTATES?
Protraction
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint LATERALLY ROTATES?
Retraction
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint HORIZONTALLY ABDUCTS?
Retraction
What is the corresponding movement of the Shoulder Girdle when the Shoulder Joint HORIZONTALLY ADDUCTS?
Protraction
Define Scapulohumeral Rythmn.
Describes the movement relationship between the shoulder girdle and the shoulder joint.
Define how the Scapulohumeral Rhythm works.
The first 30 degrees of the shoulder joint movement is purely in the glenohumeral joint.
After the first 30 degrees, every 2 inches of shoulder flexion or abduction the scapula rotates 1 in.
