What is the anterior nerve?

The human nervous system is a network of central and peripheral nerves, running from the base of the brain, mixing and out in all parts of the body. The nerve is basically a way for electrochemical impulses for traveling and helping us feel and move. Each front nerve gives these functions forward parts of our body, such as the chest and the front of the foot.

Impulses or messages of feeling or movement are transmitted by individual neurons in the nerve. The pulse is transmitted from one neuron to the other at exceptionally high speeds. The message is electric in the nerve cell, then chemically transmitted to another nerve cell, where the process begins again, allowing the impulse to travel from the cell to the cell. Nerves can contain two types of nerve cells, named for their function instead of their position. Afferent or skin nerves are those that give the feelings of the skin, a feeling of touch. Effects or interosseous nerves are those that carry the pulses that move our muscles. Some nerves serve both functions and provide roundsSlovaks and movement impulses.

In the spinal cord, the nerves are paired in the bundles of fibers that leave the spinal cord at the back, called the rear or front, called the front position. These nerves are also called dorsal or ventral nerves. Where the nerves meet with spinal cord, it is called the nerve root. Each nerve root contains the rear and front root in the nerve bundle. At this point, the front root transmits motor signals to the spinal cord and the back nerve root transmits sensory information.

The anterior nerve root is less than the rear, because it carries fewer bundles of nerves, except for the first cervical nerve root, where the front nerve root is larger. The size ratio between the front and the rear nerves depends on the location of the nerves. In the cervical spine, the roots of the rear nerve are usually three times larger than the roots of the front nerve.

There are 31 pairs of nerves that leave the spinal cord on holes in vertebrae known as foramin. The first eight nerves youIt steps on the cervical spine, neck, another 12 exit from the thoracic spine. Another five outputs on the lumbar spine, lower back. There are five pairs of nerves on the sacral spine and the final nerve leaves in the highest vertebra Coccyx.
