Radial Nerve Anatomy

It innervates essentially all the muscles on the posterior aspect of our arms and is therefore a large nerve. The radial nerve derives from the posterior cord of the brachial plexus and exits the axilla posteriorly the brachial artery.

Movement and sensation of the wrist and hand.

Radial nerve anatomy. There are four branches of the radial. The radial nerve is one of the major nerves of the upper extremity. The radial nerve lies posterior to the axillary artery in the axilla and enters the posterior compartment of the arm under teres major muscle.

It arises from the posterior cord of brachial plexus and contains fibres from nerve roots c5 to t1. Inferior lateral cutaneous nerve of arm originates in arm. These motor branches innervate the medial and long heads of the triceps.

In the posterior compartment of the arm it winds it way around the spiral groove of the humerus accompanying profunda brachii artery. Forming in the area of the shoulder joint at the confluence of several branches of the brachial plexus the radial nerve courses down the arm past the elbow joint into the forearm across the wrist and all the way to the tips of your fingers. Cutaneous innervation by the radial nerve is provided by the following nerve branches.

The radial nerve anatomical course. The radial nerve is the terminal continuation of the posterior cord of the brachial plexus. Posterior cutaneous nerve of arm originates in axilla.

The radial nerve is an essential component of the upper limb innervation network. It innervates essentially all the muscles on the posterior aspect of our arms and is therefore a large nerve. Posterior cutaneous nerve of forearm originates in arm.

Movement of the triceps muscle at the back of the upper arm. Radial nerve originates from the posterior cord of the brachial plexus c5 t1. The radial nerve innervates the muscles located in the posterior arm and posterior forearm.

Radial neuropathy occurs when there is damage to the radial nerve which travels down the arm and controls. It passes with the deep brachial artery and gives two motor branches and one sensory branch before traversing the triangular interval. Ability to bend the wrist and fingers backward.

Radial nerve it is a major peripheral nerve in the upper limb.
