100
The origination attachment for the infraspinatus muscle.
What is the infraspinous fossa?
100
The most common direction of a glenohumeral dislocation.
What is anterior?
100
The direction of the slide with abduction
What is inferior?
100
The motion produced when a muscle passes posterior to the vertical axis.
What is external rotation?
100
The insertion of the deltoid muscle.
What is the deltoid tuberosity?
200
The fibrocartilagenous ring attached to the rim of the glenoid fossa, which serves to deepen the articular cavity.
What is the glenoid labrum?
200
Spiral fractures of the humerus are likely to injure this nerve, as it passes very close to the bone.
What is the radial nerve?
200
The direction of the slide with internal rotation.
What is posterior?
200
The motion produced when a muscle passes inferior to the sagittal axis.
What is adduction?
200
This muscle is the most inferior muscle that has any effect on the shoulder joint.
What is the latissimus dorsi?
300
Provides attachment for the subscapularis muscle.
What is the lesser tuberosity?
300
An inflammation and fibrosis of the glenohumeral joint capsule.
What is adhesive capsulitis?
300
The direction of the roll with horizontal adduction.
What is anterior?
300
The line of pull of the clavicular portion of the pectoralis major.
What is anterior to the frontal axis, inferior to the sagittal axis, and anterior to the vertical axis.
300
These two muscles of the shoulder serve as both agonists and neutralizers to each of their actions.
What is the deltoid and pectoralis major?
400
The area of the humerus between the surgical neck proximally and the epicondyles distally.
What is the shaft (diaphysis) of the humerus?
400
A fracture caused by the presence of a tumor.
What is a pathological fracture?
400
The direction of the spin with hyperextension.
What is anterior.
400
This muscle serves as the most optimal neutralizer of external rotation when the desired motion is pure shoulder hyperextension.
What is latissimus dorsi.
400
The single nerve root most likely responsible if the PTA observes weakness in the coracobrachialis more so than the biceps or brachialis muscles.
What is the C7 nerve root? The biceps and brachialis have contributions from C5 and C6 only, while the coracobrachialis has a C7 contribution.
500
Provides the insertion attachment for the lattisimus dorsi and teres major.
What is the medial lip of the bicipital groove or crest of the lesser tubercle.
500
An overuse syndrome affecting the soft tissue structures between the acromial arch and the humeral head.
What is impingement syndrome?
500
The reason why a PT or PTA mobilizes the shoulder in an inferior direction with a loss of overhead flexion ROM.
What is to stretch the inferior joint capsule.
500
The action when a muscle passes posterior the frontal axis, superior to the sagittal axis and posterior the vertical axis.
What is extension (hyperextension), abduction and external rotation?
500
The muscle actions of the teres minor and infraspinatus.
What is lateral rotation and horizontal abduction?
