In human anatomy the arm is the part of the upper limb between the glenohumeral joint shoulder joint and the elbow joint.

Anatomy of nerves in arm. 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. These nerves merge to form a network called the brachial plexus before continuing into the arm. Instant anatomy is a specialised web site for you to learn all about human anatomy of the body with diagrams podcasts and revision questions.

Radial nerves span the brachial plexus and forearm. 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. In common usage the arm extends to the hand.

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. The brachial plexus refers to a group of nerves that serve the skin and muscles of the arm. It begins in the spine and runs down the arm.

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. The humerus is the bone of the arm that articulates with the scapula proximally and with the radius and the ulna distally. The axillary musculocutaneous median radial and ulnar nerves.

The brachial plexus is divided into five different divisions. 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. Five major nerves extend from the brachial plexus into the arm.

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. Above this point the median nerve provides no muscular or cutaneous innervation. Watch the following video tutorials to learn everything about the bones of 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. Skin in the posterior forearm and extensor muscles of the hand and fingers are supplied by the branches of the radial nerve. The nerves of the arm and hand.
