50
Q

Motor supply from axillary nerve?

A

Deltoid and teres minor

51
Q

Motor supply from median nerve

A

Forearm flexors except FCU and hand muscles - thumb

52
Q

Motor supply from radial nerve

A

Extensors of arm - triceps brachii and forearm and hand

53
Q

Motor supply from ulnar nerve

A

Some flexors of forearm - FCU

Flexors of hand

54
Q

Carpal tunnel syndrome?

A

Compression of the median nerve.

55
Q

What test can be used to diagnose Carpal tunnel syndrome?

A

Tinel’s test

56
Q

Guyon’s canal

A

Ulnar nerve passes through it, located at carpal bones

57
Q

Dermatome

A

Area of skin innervated by a single spinal nerve

58
Q

Myotome

A

A group of muscles innervated by a single spinal nerve

59
Q

Erb’s palsy

A

Severing upper trunk of brachial plexus. Affects C5 and C6. Causes medial rotation and paralysis of arm. Can occur during childbirth

60
Q

Klumpke’s palsy

A

Severing lower trunk of brachial plexus causing claw hand (middle and index finger cannot extend). Can occur during childbirth

61
Q

hand of benediction

A

Compression of the median nerve at forearm or elbow, causing inability to flex the middle and index fingers

62
Q

Arterial supply to the arm

A

Subclavian, axillary, brachial, ulnar and radial.

63
Q

Arterial supply to the hand

A

the radial and ulnar arteries anastomose to form superficial and deep palmar arches

64
Q

Volkmann’s ischaemia

A

Lack of blood flow to arm from severing or occlusion causing abnormal flexion - claw hand. can be caused by compartment syndrome or trauma

65
Q

Superficial veins of upper limb

A

Cephalic and basilic

66
Q

Deep veins of upper limb

A

Brachial, ulnar and radial

67
Q

Where is a common site to take blood from/ venapuncture?

A

Median cubital vein

68
Q

Compartment syndrome

A

Fascia surrounds each muscle compartment and so when there is injury that causes significant swelling/ bleeding this can cause increased pressure which restricts blood flow to the muscles and damages the nerves and muscle fibres.
