Question 2
Question
What muscle is NOT innervated by the Musculocutaneous nerve?
Answer
Coracobrachialis
Biceps Brachii
Brachialis
Brachioradialis
Question 3
Question
Which fact is incorrect for Pectoralis Major?
Answer
Attachments include medial 1/2 of clavicle, anterior sternum, coastal cartilages ribs 1-6, and medial lip of bicipital groove
Innervated by both medial and lateral pectoral nerves
Main action is adduction, horizontal adduction and medial rotation of shoulder
Synergists include latissimus dorsi, subscapularis and teres major
Question 4
Question
Which action is NOT performed by Coracobrachialis?
Answer
Flexion at shoulder
Adduction at shoulder
Horizontal adduction at shoulder
Medial rotation at shoulder
Question 5
Question
Which statement is TRUE?
Answer
Serratus Anterior, O: Costal surface of medial border of scapula I: Ribs 1-9
The Quadrangular space is made up of Teres Major, Teres Minor, Triceps Brachii and the Humerus
Supraspinatus is most active AFTER 30 degrees of adduction at the shoulder
Biceps brachii inserts onto the bicipital aponeurosis and the ulnar tuberosity
