deltoid (axillary nerve)
supraspinatus (suprascapular nerve)
infraspinatus (suprascapular nerve)
teres major (lower scapular nerve)

rhomboid minor

Question 8

Muscles of the anterior fascial compartment of the forearm

Answer 8

pronator teres - humeral head, ulnar head
flexor carpi radialis
palmaris longus

• supplied by median nerve
• flexor carpi ulnaris - humeral, ulnar head - ulnar nerve

flexor digitorum superficialis - humeroulnar, radial head
- median nerve

flexor pollicis longus - median

flexor digitorum profundus - ulnar (medial half) median (lateral half)

pronator quadratus - median nerve

lumbricals (4)
interossei (8) - palmar, dorsal
-ulnar except lumbricals lateral 1,2 - median, 3,4 - ulnar nerve

short muscles of the thumb -all median nerve except adductor pollicis
