Part ONE
o
The long head of the biceps arises from the __________ within the shoulder joint.
 Supraglenoid tubercle
o
The biceps is a flexor of the:
 Elbow
o
Tendons of the rotator cuff support the articular capsule of the shoulder joint. The tendon
which provide support anteriorly is the:
 Subscapularis
o
Blood supply to the glenoid labrum is from the:
 Suprascapular artery
 Circumflex scapular artery
 Posterior circumflex humeral artery
o
The thick, triangular muscle which covers the anterior, posterior and lateral aspects of the
shoulder is the:
 Deltoid
o
The deltoid is a powerful abductor of the
 Humerus
o
The rotator cuff consists of
 Subscapularis
 Supraspinatus
 Infraspinatus
 Teres minor
o
These tendons of the rotator cuff act together to stabilize the _______________ joint.
 Glenohumeral joint
o
The tendons of the rotator cuff have a thickness of
 5-10 mm
o
With the arm abducted, the subscapularis draws the humerus
 Forward and inferior
o
This large triangular muscle arises from the entire circumference of the subscapular
fossa.
 Subscapularis
o
The ______________ aids the Deltoid in abducting the arm, and maintains the humeral
head in the glenoid cavity.

Supraspinatus
o
The Infraspinatus muscle acts to rotate the humerus
 Externally
o
The _______________ opposes the actions of the deltoid, biceps brachii, and triceps to
prevent upward subluxation of the humerus.
 Teres minor
o
The thin, flat ligament which extends from the base of the coracoid to the medial end of
the scapular notch is the
 Superior transverse scapular ligament
o
The strong triangular band connecting the coracoid and the acromium is known as the
 Coracoacromial ligament
o
A history of ____________ may predispose a patient to “frozen shoulder:
 Diabetes
o
The best position for a shoulder examination is with the patient
 Seated on a rotating stool
o
Anisotropy occurs when
 Insonation is not perpendicular to tendon
o
Anisotropy results in the tendon appearing
 Hypoechoic
