Question 5

Serratus anterior

Answer 5

**originates on the superolateral surfaces of the first to eighth or ninth ribs at the lateral wall of the thorax **inserts along the superior angle, medial border, and inferior angle of the scapula.
** long thoracic nerve
**Rotation of the scapula

Question 6

Coracobrachialis

Answer 6

**originates from the deep surface of the coracoid process of scapula.
**insert onto the anteromedial surface of the humeral shaft.
**musculocutaneous nerve (C5-C7)
**flexion and adduction

Question 7

Supraspinatus

Answer 7

**Originates from the supraspinous fossa of the scapula
**inserts to the greater tubercle of the humerus.
**Innervation: Suprascapular nerve.
**abd and er

Question 8

Infraspinatus

Answer 8

**originates at the scapula
** inserts at the tubercle of the humerus
**suprascapular nerve.
**external rotation of the shoulder joint

Question 9

Teres minor

Answer 9

**originates on the lateral border of the scapula
**inserts onto the greater tubercle of the humerus
**axillary nerve
**laterally rotates the humerus

Question 10

Brachioradilis

Answer 10

**originates from the lateral supracondylar ridge of the humerus and the lateral intermuscular septum.
**inserts onto the styloid process of the radius.
**flexes the forearm at the elbow.

Answer 11

**Originates from lateral epicondyle of humerus
**Insertion Lateral proximal radial shaft
**radial nerve
**rotates the radius laterally at the proximal radioulnar joint

Question 12

Extensor carpi radialis longus

Answer 12

**originates from the lateral epicondyle and lateral supracondylar ridge of the humerus
**inserts onto the dorsal surface of the second metacarpal associated with the index finger.
**radial nerve
**radial deviation

Question 13

Extensor carpi radialis brevi

Answer 13

**originates from the lateral epicondyle of the humerus
**inserts at the base of the third metacarpal on the radial side of the dorsal surface
**radial nerve
**extend and abduct the hand at the wrist joint.

Question 14

Extensor digitorum longus

Answer 14

**radial nerve
**Originates from the lateral epicondyle of the humerus
**insert finger 2-5
**extension of four medial fingers

Question 15

Interossei

Answer 15

** ulnar nerve
**finger abd and add
**originate along the shaft of the metacarpal bone
**inertion base of the proximal phalanx

Question 16

Extensor pollicis longus and brevis

Answer 16

**originates from the middle third of the posterior surface of ulna
**inerts to interosseous membrane.
**Thumb extension
**radial nerve

Question 17

Abductor pollicis longus

Answer 17
