Spinal Nerves

Spinal nerves, a part of the peripheral nervous system (PNS), are mixed nerves that send motor, sensory, and autonomic signals between the CNS and the body.

The spinal nerves branch into the dorsal ramus, ventral ramus, the meningeal branches, and the rami communicantes.

A nerve plexus is a network of intersecting nerves  that serve the same part of the body.

The anterior divisions of the thoracic spinal nerves (T1–T11) are called the intercostal nerves.

A dermatome is an area of skin that is supplied by a single spinal nerve, and a myotome is a group of muscles that a single spinal nerve root innervates.

Spinal nerves connect the brain and spinal cord to the limbs and organs of the body.
