The brachial plexus refers to a group of nerves that serve the skin and muscles of the arm.

Anatomy of nerves in arm. The brachial plexus is divided into five different divisions. In common usage the arm extends to the hand. It begins in the spine and runs down the arm.

Watch the following video tutorials to learn everything about the bones of the arm. The nerves of the arm and hand. We are pleased to provide you with the picture named neck nerves and innervation of shoulder arm and hand.

Neck nerves and innervation of shoulder arm and hand in this image you will find neck nerves and innervation of shoulder arm and hand in it. Along the anterior of the forearm the median and ulnar nerves supply nerve signals to the skin and to the flexor muscles of the hand and fingers. In human anatomy the arm is the part of the upper limb between the glenohumeral joint shoulder joint and the elbow joint.

The ulnar and median nerves originate in the brachial plexus which is a bundle of nerve fibers extending from the spinal cord to the arm and ending in the hand. There are four main nerves of the arm and they wrap around the bones.

Above this point the median nerve provides no muscular or cutaneous innervation. The axillary nerve is a branch of the brachial plexus which contains nerve fibres from c5 and c6 it provides sensory innervation to the skin on the regimental badge area of the upper arm and motor innervation to the deltoid and teres minor muscles. It can be divided into the upper arm which extends from the shoulder to the elbow the forearm which extends from the elbow to the hand and the hand.

Skin in the posterior forearm and extensor muscles of the hand and fingers are supplied by the branches of the radial nerve. The axillary musculocutaneous median radial and ulnar nerves. As it descends the arm it travels over the brachial artery then under the bicipital aponeurosis a sheath of connective tissue that inserts the biceps brachii to the proximal forearm creating the cubital fossa.

The humerus is the bone of the arm that articulates with the scapula proximally and with the radius and the ulna distally. Five major nerves extend from the brachial plexus into the arm. Each of these nerves carries information in the form of nerve impulses to and from a particular region of the arm and hand.
