Which of the following rotator cuff muscles does not insert at the greater tuberosity of the humerus?

• Subscapularis

• Supraspinatus

• Infraspinatus

• Teres Minoir

Which of the following muscles performs these actions: adduction, horizontal adduction, internal rotation of the humerus

• Pectoralis Minor

• Pectoralis Major

• Infraspinatus

• Upper Trapezius

The Painful Arc test determines if the athlete has...

• Torn Rotator Cuff

• Impingement

• Winging of the Scapula

• Thoracic Outlet Syndrome

Which of the following are terms used to describe injuries to the labrum?

• Subluxed shoulder syndrome

• Tenosynovitis and Capsular degeneration

• SLAP tear and Bankhart lesion

• Dislocated and Subluxed

An athlete presents with winging of the scapula and you suspect a group of muscles are not firing properly. The muscles insert at the:

Upper lateral ⅓ of clavicle and acromion of scapula

Middle- Spine of scapula

Lower- Spine of scapula

Which group of muscles do you suspect is not firing properly?

• Rotator Cuff muscles

• Pectoralis Muscles

• Biceps and Triceps

• Trapezius Muscles

Your personal trainer tells you to engage your muscles that are responsible for extension, internal rotation, and adduction. Which muscles is your trainer telling you to engage?

• Biceps Brachii and Triceps

• Supraspinatus and Teres Minor

• Rhomboids and Trapezius muscles

• Latissimus Dorsi and Teres Major

Which two muscles of the rotator cuff are responsible for external rotation and extension of the humerus?

• Supraspinatus and Teres Minor

• Teres Minor and Infraspinatus

• Subscapularis and Supraspinatus

• Teres Major and Lateral Deltoid

This muscle of the upper back is responsible for elevation and medial downward rotation of the scapula.

• Levator Scapula

• Latissimus Dorsi

• Supraspinatus

• Biceps Brachii

An athlete complains of pain following a heavy shoulder workout. You determine they have pain at the anterior lateral 1/3 of the clavicle and they struggle to anterior flex their humerus and ABduct their humerus to 90 degrees. Which muscle is injured?

• Rotator Cuff

• Rhomboids

• Deltoids

• Levator Scapula

Which of the following tests involve the biceps?
