Nerves Spinal

Spinal nerves (lat. nervi spinales) are nerves that are located in the spinal canal and innervate the muscles, joints and organs located on the torso and limbs. They are part of the peripheral nervous system and consist of many fibers that form bundles of nerve fibers.

Spinal nerves start from the spinal cord and end at the muscles, joints and organs. They are divided into anterior, posterior and lateral nerves, each of which has its own functions and areas of innervation.

The anterior spinal nerves innervate the anterior part of the trunk and limbs, including the muscles of the neck, chest, abdomen, arms and legs. They are also involved in the regulation of blood circulation and respiration.

The posterior spinal nerves are responsible for innervation of the posterior part of the trunk and limbs. They control the muscles of the back, buttocks, thighs, legs and feet.

The lateral spinal nerves supply innervation to the side of the torso and head, including the muscles and joints of the arms, shoulders, neck, head, and face.

Each nerve of the spinal system has many branches that diverge in different directions and provide innervation to different areas of the body. In addition, the spinal system also includes the meninges, which protects the spinal cord and nerves from damage.

In general, the spinal nerves are an important part of the peripheral nervous system, which provides control over the muscles, joints and organs in the human body. Disruption of the spinal nerves can lead to various diseases, such as radiculitis, osteochondrosis and others, so it is necessary to monitor their health and prevention.
