Radial Nerve Anatomy

Posterior cutaneous nerve of forearm originates in arm. Radial nerve originates from the posterior cord of the brachial plexus c5 t1.

Accessphysiotherapy Brachial Plexus And Peripheral Nerves

The radial nerve innervates the muscles located in the posterior arm and posterior forearm.

Radial nerve anatomy. There are four branches of the radial. Inferior lateral cutaneous nerve of arm originates in arm. It innervates essentially all the muscles on the posterior aspect of our arms and is therefore a large nerve.

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. The radial nerve derives from the posterior cord of the brachial plexus and exits the axilla posteriorly the brachial artery. Posterior cutaneous nerve of arm originates in axilla.

The radial nerve lies posterior to the axillary artery in the axilla and enters the posterior compartment of the arm under teres major muscle. Radial neuropathy occurs when there is damage to the radial nerve which travels down the arm and controls. Ability to bend the wrist and fingers backward.

Cutaneous innervation by the radial nerve is provided by the following nerve branches. It innervates essentially all the muscles on the posterior aspect of our arms and is therefore a large nerve. Radial nerve it is a major peripheral nerve in the upper limb.

Movement and sensation of the wrist and hand. It arises from the posterior cord of brachial plexus and contains fibres from nerve roots c5 to t1. Movement of the triceps muscle at the back of the upper arm.

It passes with the deep brachial artery and gives two motor branches and one sensory branch before traversing the triangular interval. The radial nerve anatomical course. The radial nerve is the terminal continuation of the posterior cord of the brachial plexus.

These motor branches innervate the medial and long heads of the triceps. The radial nerve is an essential component of the upper limb innervation network. In the posterior compartment of the arm it winds it way around the spiral groove of the humerus accompanying profunda brachii artery.

The radial nerve is one of the major nerves of the upper extremity.
