How many nerves are in the upper limb?

five
This article will focus on the five terminal nerve branches of the brachial plexus which supply the upper limb. These are the musculocutaneous nerve, the axillary nerve, the radial nerve, the median nerve and the ulnar nerve.

What is the nerve innervation of the upper limbs?

The brachial plexus is a collection of nerve fibres that supply motor and sensory innervation to the upper limb. It originates from nerve roots C5 to T1 and, as it passes through the axilla, merges the nerve fibres from these roots into different nerve branches.

What are the 5 major nerve Innervations of shoulder arm?

Branches. The fifth and final level of the brachial plexus are the five nerves that feed the shoulder and arm called “branches.” These five branches are named the musculocutaneous, axillary, radial, median, and ulnar nerves.

What are the three main nerves in your arm?

Three main nerves run past the elbow and wrist to the hand….Nerves of the Arm

• Median nerve. This nerve passes down the inside of the arm and crosses the front of the elbow.
• Ulnar nerve. This nerve passes down the inside of the arm.
• Radial nerve. This nerve passes down the back and outside of the upper arm.

What nerve Innervates the top of the shoulder?

The suprascapular nerve comes off the upper trunk, from roots C5-C6, and innervates the supraspinatus and infraspinatus, which are contributors to the rotator cuff apparatus.

Where do the nerves serving the upper limbs originate?

The nerves of the upper limb arise from a network called the brachial plexus, which originates in the neck from anterior divisions of the spinal nerves C5-T1.
