Question 34

Answer 34

Flexor carpi radialis

Question 35

Answer 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

Question 36

Answer 36

Flexor digitorum superficialis

(there is a flexor digitorum superficialis and profundus. Profundus means deeper. The profundus flexes the distal interphalangeal joints)

Question 43

Answer 43

Extensor carpi ulnaris

Question 44

Answer 44

Extensor digitorum

Question 45

Answer 45

Extensor pollicis longus

Question 46

Answer 46

Extensor pollicis brevis

Question 47

Answer 47

Abductor pollicis longus

Question 48

Answer 48

Extensor carpi radialis brevis

Question 49

Answer 49

Extensor carpi radialis longus

Question 50

What are the muscles in the superficial compartment of the anterior forearm?

Answer 50

Flexor carpi ulnaris

Palmaris longus

Flexor carpi radialis

Pronator teres

Question 51

What are the muscles in the intermediate compartment of the anterior forearm?

Answer 51

Flexor digitorum superficialis

Question 52

What are the muscles in the deep compartment of the anterior forearm?

Answer 52

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

Question 53

Which nerve innervates the anterior compartment of the upper arm?

Answer 53

Musculocutaneous

Biceps brachii

Brachialis

Coracobrachialis

Question 54

Which nerve innervates the posterior arm?

Answer 54

Radial nerve

(posterior extensors of the forearm and triceps)

Question 55

What are the superficial muscles in the posterior compartment of the forearm?

Answer 55

Question 56

What are the deep muscles in the posterior compartment of the forearm?

Answer 56

Question 57

Which forearm muscles are innervated by the ulnar nerve?

Answer 57

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

Question 58

Which hand muscles are innervated by the median nerve?

Answer 58

1/2 loaf

L - lateral lumbricals (1st and 2nd digit)

+ the thenar muscles

O - opponens pollicis

A - adductor pollicis brevis

F - flexor pollicis brevis

Which hand muscles are innervated by the median nerve?

Answer 59

Thenar muscles

Lateral two lumbricals

(the rest are innervated by the ulnar nerve)

Question 60

What are the thenar muscles?

Answer 60

Opponens pollicis

Abductor pollicis brevis

Flexor pollicis brevis

Question 61

Which structures pass through the axilla?

Answer 61

Axillary artery

Axillary vein

Axillary lymph nodes

Brachial plexus

Biceps and coracobrachialis

Question 62

What are the boundaries of the cubital fossa?

Answer 62

Superior: imaginary line between the epicondyles of the humerus

Lateral: medial border of the brachioradialis

Medial: lateral border of the pronator teres

Question 63

Answer 64

(radial and ulnar are mixed up in this diagram)

Question 65

Label this diagram

(deep veins of the upper limb)

Answer 65

Question 66

Label this diagram

(superficial veins of the upper limb)

Answer 66

Question 67

What does an upper brachial plexus injury look like and what nerve roots are affected?

Answer 67

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.

Answer 68

C5-7

Question 69

Which nerve roots form the axillary nerve?

Answer 69

C5-6

Question 70
