A better question might be which nerves innervate muscles in the arm, or for a specific muscle what is its innervation. Some of the upper extremity (arm) muscles & their innervations from proximal to distal (close to the body to far from the body) include:
- pectoralis major - lateral and medial pectoral nerves
- pectoralis minor - medial pectoral nerve
- subclavius - nerve to subclavius
- serratus anterior - long thoracic nerve
- trapezius - accessory nerve & C3-4 nerve roots
- latissimus dorsi - thoracodorsal nerve
- levator scapulae - dorsal scapular nerve & C3-4 nerve roots
- rhomboid major & minor - dorsal scapular nerve
- deltoid - axillary nerve
- supraspinatus - suprascapular nerve
- infraspinatus - suprascapular nerve
- teres minor - axillary nerve
- teres major - lower subscapular nerve
- subscapularis - upper and lower subscapular nervers
- biceps brachii - musculocutaneous nerve
- brachialis - musculocutaneous nerve
- coracobrachialis - musculocutaneous nerve
- triceps brachii - radial nerve
- anconeus - radial nerve
- pronator teres - median nerve
- flexor carpi radialis - median nerve
- palmaris longus - median nerve
- flexor carpi ulnaris - ulnar nerve
- flexor digitorum superficialis - median nerve
- medial flexor digitorum profundus - ulnar nerve
- lateral flexor digitorum profundus - anterior interosseous branch of median nerve
- flexor pollicis longus - anterior interosseous branch of median nerve
- pronator quadratus - anterior interosseous branch of median nerve
- brachioradialis - radial nerve
- extensor carpi radialis longus - radial nerve
- extensor carpi radialis brevis - radial nerve
- extensor digitorum - posterior interosseous branch of radial nerve
- extensor digiti minimi - posterior interosseous branch of radial nerve
- extensor carpi ulnaris - posterior interosseous branch of radial nerve
- supinator - - deep branch of radial nerve
- extensor indicis - posterior interosseous branch of radial nerve
- abductor pollicis longus - posterior interosseous branch of radial nerve
- extensor pollicis longus - posterior interosseous branch of radial nerve
- extensor pollicis brevis - posterior interosseous branch of radial nerve
- opponens pollicis - median nerve
- abductor pollicis brevis - median nerve

- flexor pollicis brevis superficial head - median nerve
- flexor pollicis brevis deep head
- adductor pollicis - ulnar nerve
- abductor digiti minimi - ulnar nerve
- flexor digiti minimi brevis - ulnar nerve
- opponens digiti minimi - ulnar nerve
- 1st & 2nd lumbricals - median nerve
- 3rd & 4th lumbricals - ulnar nerve
