What nerve innervates the dorsal hand?

The 3 nerves involved in dorsal hand sensory innervation are the superficial branch of the radial nerve (SBRN), the dorsal branch of the ulnar nerve (DBUN), and the lateral antebrachial cutaneous nerve (LABCN).

What are the three nerves that innervate the hand?

Nerves in hand Three nerves control function in our hands: the median, ulnar, and radial nerves. Each of these nerves is responsible for both sensory and motor function in different parts of the hand.

What nerve provides sensation to the dorsal thumb?

The median nerve
The median nerve also provides sensory innervation to the dorsal aspect (nail bed) of the distal first two digits of the hand, the volar aspect of the thumb, index, middle, and half of the ring finger, the palm, as well as the medial aspect of the forearm.

What does ulnar nerve innervate?

The ulnar nerve innervates the flexor muscles of the forearm including the flexor carpi ulnaris and flexor digitorum profundus. It also innervates the intrinsic muscles of the hand including the palmaris brevis, lumbricals, hypothenar and interossei muscles.

What is innervated by ulnar nerve?

Why is the top of my hand numb?

Hand numbness can be caused by damage, irritation, or compression of one of the nerves or a branch of one of the nerves in your arm and wrist. Diseases affecting the peripheral nerves, such as diabetes, also can cause numbness, although with diabetes, similar symptoms usually occur first in your feet.

What nerve is pinched to causes numbness in fingers?

A pinched median nerve in your wrist can lead to pain, numbness and weakness in your hand and fingers (carpal tunnel syndrome).

What is innervated by the axillary nerve?

The axillary nerve has both a motor and a sensory distribution of innervation. It has motor fibres that innervate the deltoid muscle, acting as an abductor, flexor and extensor at the shoulder joint, as well as the teres minor muscle, allowing lateral rotation of the glenohumeral joint.
