What is the sensory area of radial nerve?

What is the sensory area of radial nerve?

The superficial branch of the radial nerve provides sensory innervation to much of the back of the hand, including the web of skin between the thumb and index finger.

What does the radial nerve innervate?

The radial nerve is one of five main branches of the brachial plexus. It provides motor and sensory innervation to the arm and forearm and sensory innervation to the hand.

Where is the dorsal sensory branch of radial nerve?

The medial branch communicates, above the wrist, with the dorsal branch of the lateral antebrachial cutaneous, and, on the back of the hand, with the dorsal branch of the ulnar nerve.

In what appendage is the radial nerve located?

The appendage that the radial nerve is located in is the arm.

What muscles are innervated by superficial branch of radial nerve?

Along its course in the arm region, the radial nerve provides muscular branches that innervate the triceps brachii, anconeus, and brachioradialis muscles.

What appendages is the radial nerve located in?

Is radial nerve sensory or motor?

Upon crossing the cubital fossa, the radial nerve terminates by dividing into two terminal branches: superficial (sensory) and deep (motor).

What is the sensory function of the axillary nerve?

Your axillary nerve, also known as the circumflex nerve, is one of five peripheral nerves that run through your shoulder. Axillary nerves start in your neck at the brachial plexus (a network of nerves in your shoulder). This network of nerves enables movement and sensation to your upper limbs.

Is axillary nerve sensory?

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.

What is the radial nerve?

The Radial Nerve. The radial nerve is a major peripheral nerve of the upper limb. In this article, we shall look at the anatomy of the radial nerve – its anatomical course and its motor and sensory functions. We shall also consider the clinical consequences of damage to the nerve.

What are spinal nerves and dermatomes?

Spinal nerves help to relay information from other parts of your body to your central nervous system. As such, each dermatome transmits sensory details from a particular area of skin back to your brain. Dermatomes can be helpful in evaluating and diagnosing conditions affecting the spine or nerve roots.

What is the difference between dermatomal and peripheral nerve fields?

The receptive field of a peripheral sensory nerve (peripheral nerve field) crosses over different dermatomes. A dermatome is an area of skin supplied by a single spinal nerve. Therefore, the map of peripheral nerve fields over the body differs from the dermatomal distribution since individual peripheral nerves are composed of multiple nerve roots.

How can a dermatome map be used to diagnose nerve damage?

Clinicians can use test touch with a dermatome map as a way to localise lesions, damage, injury to specific spinal nerves, and to determine the extent of the injury, for example, if a patient is experiencing numbness in only one area.
