What are the nerves of the hand?

The nerves of the hand are the blood vessels of the nervous system that innervate hands and fingers. This vessel, which, after crossing the wrist, branches in their hand into smaller nerves, comes from the three main nerves, which take place after the arm: radial, median and ulnar nerves. The nerves of the hand transmit signals known as afferent or eperential, which run towards or from or from the central nervous system, which is the nerve of the hand transfers information to the brain of the brain. The information that travels from brain to hand includes motor signals that say muscles to move their hands and fingers. On the contrary, traveling from hand to brain includes sensory signals that send brain messages about touch, such as whether the object feels soft or sharp and pain.

coming from the nerve roots climbing into the spinal cord at the height of four lower cervical vertebrae and the highest thoracic vertebra in the throat, radial, middle and ulnar nerves of the hand begin tightlyAbove the shoulder and crossing the arms down. The radial nerve travels on the same side of the arm as the bone of the radius in the forearm, the inch side of the arm. Similarly, Ulnar nerve is found on the side of the ulna bone in the forearm or on the side of the side. Middle nerve, as the name suggests, runs down in the middle of the arm and enters the hand through the carpal tunnel in the center of the wrist.

Radial nerve, after serving many muscles found on the back of the arm, is a superficial nerve as soon as it reaches the forearm, which means it lies near the skin. Its superficial branch gives a large part of the back surface of the hand, namely the skin and its sensory receptors. The branches of this nerve innervate both sides of the rear of the index finger, the radial side of the back of the ring, both sides of the rear of the middle finger and the radial ulnar side of the back of the thumb.

beside the radial nerve is the middle nerve, in the middle of the three main nerves of the hand. Runs directly down to the center of the forearm and enters the hand using a carpal tunnel, a passage between a cluster of carpal bones tEasily behind the wrist. This nerve also adds the skin of the first three fingers on the palms of the hand, as well as the lumbrické muscles on the radial side of the hand, the deep muscles between the bones in the palm that help to bend and stretching the fingers.

The third main nerve of the hand is Ulnar nerve. It comes into the hand along the pallet and is more superficial than the middle nerve, although once in the hand it is divided into superficial and deep branches. The superficial branch innervates the muscles of Palmaris Brevis and the skin on the Ulnar part of the hand. It also adds the skin on the surface of the palm of both sides of the pinky and Ulnar side of the ring. Under this deep branch of Ulnar nerve, many hand muscles, including those spread and combine fingers, and those that perform the opposition, the act of bringing the thumb in to touch the tips of four fingers.
