Triquetral
31
Flexor digitorum profundus
32
Pronator quadratus
33
Pronator teres
34
Flexor carpi radialis
35
Palmaris longus
Absent in 15% of the population
Does not travel through the carpal tunnel so can see the tendon at the wrist when the thumb and pinky touch
36
Flexor digitorum superficialis
(there is a flexor digitorum superficialis and profundus. Profundus means deeper. The profundus flexes the distal interphalangeal joints)
37
Flexor carpi ulnaris
38
Flexor pollicis longus
39
Brachioradialis
40
Extensor digiti minimi
41
Extensor indicis
42
Supinator
43
Extensor carpi ulnaris
44
Extensor digitorum
45
Extensor pollicis longus
46
Extensor pollicis brevis
47
Abductor pollicis longus
48
Extensor carpi radialis brevis
49
Extensor carpi radialis longus
50
What are the muscles in the superficial compartment of the anterior forearm?
Flexor carpi ulnaris
Palmaris longus
Flexor carpi radialis
Pronator teres
51
What are the muscles in the intermediate compartment of the anterior forearm?
Flexor digitorum superficialis
52
What are the muscles in the deep compartment of the anterior forearm?
Flexor digitorum profundus
Flexor pollicis longus
Pronator quadratus
Allow you to clench your fist then pronate it like you're ready to punch someone.
Flexor digitorum profundus + flexor pollicis longus = clenching
Pronator quadratus = pronation
53
Which nerve innervates the anterior compartment of the upper arm?
**Musculocutaneous**
## Footnote
Biceps brachii
Brachialis
Coracobrachialis
54
Which nerve innervates the posterior arm?
**Radial nerve**
## Footnote
(posterior extensors of the forearm and triceps)
55
What are the superficial muscles in the posterior compartment of the forearm?
56
What are the deep muscles in the posterior compartment of the forearm?
57
Which forearm muscles are innervated by the ulnar nerve?
Flexor carpi ulnaris
Flexor digitorum profundus (1/2 of it)
The ulnar nerve is sandwiched between these muscles
The rest of the anterior forearm is innervated by the medial nerve
58
Which hand muscles are innervated by the median nerve?
1/2 loaf
L - lateral **lumbricals** (1st and 2nd digit)
*+ the thenar muscles*
O - **opponens** **pollicis**
A - **adductor pollicis** **brevis**
F - **flexor pollicis** **brevis**
59
Which hand muscles are innervated by the median nerve?
Thenar muscles
Lateral two lumbricals
(the rest are innervated by the ulnar nerve)
60
What are the thenar muscles?
Opponens pollicis
Abductor pollicis brevis
Flexor pollicis brevis
61
Which structures pass through the axilla?
Axillary artery
Axillary vein
Axillary lymph nodes
Brachial plexus
Biceps and coracobrachialis
62
What are the boundaries of the cubital fossa?
Superior: imaginary line between the epicondyles of the humerus
Lateral: medial border of the brachioradialis
Medial: lateral border of the pronator teres
63
What are the contents of the cubital fossa? Medial to lateral
Median nerve
Brachial artery
Biceps tendon
Radial nerve (not always considered part of the cubital fossa)
(My Bulging Biceps Rock)

67
What does an upper brachial plexus injury look like and what nerve roots are affected?
C5/6
The affected limb hangs limply, medially rotated by the unopposed action of pectoralis major. The forearm is pronated due to the loss of biceps brachii. This is position is known as ‘waiter’s tip’, and is characteristic of Erb’s palsy.
68
Which nerve roots form the musculocutaneous nerve?
C5-7
69
Which nerve roots form the axillary nerve?
C5-6
70
Which nerve roots form the radial nerve?
C5-8
71
Which nerve roots form the median nerve?
C6-T1
72
Which nerve roots form the ulnar nerve?
C8-T1
73
Which nerve innervates the posterior arm?
Radial nerve
