Shoulder Girdle
Sternoclavicular joint motion that occurs as the inferior surface of the clavicle moves to face anteriorly
What is posterior rotation?
Companion motion of the shoulder girdle that occurs during shoulder joint internal rotation.
What is protraction?
Structural classification of the elbow joint.
What is hinge?
Structural classification of the radioulnar joint.
What is pivot?
Originates from primarily C8 and T1 nerve roots.
What is the ulnar nerve?
During sternoclavicular joint elevation, the lateral clavicle moves superior, and the medial clavicle slides in which direction?
What is inferior?
The closed-pack position of the shoulder joint.
What is abduction and external rotation?
Formed between the longitudinal axes of humerus and forearm.
What is carrying angle?
Degrees of freedom available at the radioulnar joint.
What is one?
Innervates the elbow, wrist, finger, and thumb extensors.
What is the radial nerve?
Acromioclavicular joint motion in which the glenoid fossa moves posterolaterally.
What is external rotation?
During shoulder joint flexion, the humeral head glides this direction.
What is inferior?
Open pack position of the humeroradial articulation.
What is full elbow extension and forearm supination?
It's articulation with the radial notch of ulna forms the proximal radioulnar joint.
What is the head of the radius?
Innervates the palmar and dorsal interossei.
What is the ulnar nerve?
Acromioclavicular joint motion that occurs with shoulder girdle elevation.
What is anterior tilt?
Capsular pattern of the shoulder joint.
What is external rotation, abduction, internal rotation?
Ligament that resists a varus force at the elbow.
What is the lateral collateral ligament?
Ligament that holds the head of the radius against the ulna.
What is annular ligament?
Sensory distribution is the anterolateral forearm.
What is the musculocutaneous nerve?
The TWO motions at the sternoclavicular joint that occur during shoulder girdle upward rotation.
What are elevation and posterior rotation?
The four muscles of the rotator cuff, which work together to keep the head of the humerus “rotating” against the glenoid fossa during joint motion.
What are the
•Supraspinatus
•Infraspinatus
•Teres minor
•Subscapularis
When measuring shoulder extension PROM, PTA keeps the elbow slightly flexed to avoid this phenomenon that occurs in muscles that cross multiple joints.
What is passive insufficiency of the biceps brachii?
When using the "pencil" method to measure supination ROM, this landmark serves as the axis.
What is the head of the 3rd metacarpal?
Innervates the serratus anterior.
What is the long thoracic nerve?
