FOREARM

Question 1

ANTERIOR FOREARM: SUPERFICIAL

lateral to medial

Answer 1

PRONATOR TERES
FLEXOR CARPI RADIALIS
PALMATOR LONGUS
FLEXOR CARPI ULNARIS
note that P Teres doesn’t act on the wrist joint
note that F C Ulnaris is innervated by the ulnar nerve, all the rest by the median nerve
BRACHORADIALIS also flexes the forearm, but it acts on the elbow joint and is part of the posterior compartment

Question 2

ANTERIOR FOREARM: INTERMEDIATE

Answer 2

FLEXOR DIGITORUM SUPERFICIALIS (median nerve)

4 tendons attach to the palmar surfaces of middle phalanges, of digits 2-5

Question 3

ANTERIOR FOREARM: DEEP

lateral to medial

Answer 3

FLEXOR POLLICIS LONGUS (median nerve)
PRONATOR QUADRATUS (runs laterally) (median nerve)
FLEXOR DIGITORUM PROFUNDUS (attach to distal phalanges) (medial half is innervated by the ulnar nerve)

Question 4

POSTERIOR FOREARM: SUPERFICIAL

lateral to medial

Answer 4

EXTENSOR CARPI RADIALIS LONGUS
EXTENSOR CARPI RADIALIS BREVIS
EXTENSOR DIGITORUM (digits 2-5) (extensor hoods into middle and distal phalanges 2-5)
EXTENSOR MINIMI (digit 5)
EXTENSOR CARPI ULNARIS
there are also ANCONEUS and BRACHORADIALIS

Question 5

POSTERIOR FOREARM: DEEP

lateral to medial

Answer 5

SUPINATOR
ABDUCTOR POLLICIS LONGUS
EXTENSOR POLLICIS BREVIS
EXTENSOR POLLICIS LONGUS
EXTENSOR INDICIS

Question 6

WHAT PASSES THROUGH THE CARPAL TUNNEL?

Answer 6

FLEXOR DIGITORUM SUPERFICIALIS (4 tendons)
FLEXOR DIGITORUM PROFUNDUS (4 tendons)
FLEXOR POLLICIS LONGUS (1 tendon)
MEDIAN NERVE
