A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the : Nerve plexuses are composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses—except in the thoracic region—as well as other forms of autonomic plexuses, many of .
The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes. It is also the location of groups of spinal interneurons that make up the neural circuits known C1–C6: Neck flexors. The coccyx, or tailbone, is the lowest bone of the spinal column. Many of the peripheral nerves are named after the part of the spine where they join the spinal cord. There are cervical, thoracic.
Spinal nerves emerge in pairs, one from each side of the spinal cord along its length. The cervical nerves form a plexus (a complex interwoven network of nerves—nerves converge and branch). The cervical enlargement is a widening in the upper part of the spinal cord (C 4 –T 1). Spinal nerves are bundles of nerve fibers connected to the spinal cord. These nerves carry information to and away from the spinal cord. Spinal nerves supply all the areas of the body except the head and neck region. Some structures in the head and neck region are also innervated or supplied by the spinal nerves such as muscles of the neck, etc.

Spinal nerves, considered part of the peripheral nervous system, generally refer to mixed spinal nerves, which carry motor, sensory, and autonomic information between the brain and spinal cord and the rest of the body. The cervical spinal nerves innervate the muscles and provide sensation for the head, neck, and diaphragm, as well as the upper limbs and back.

It also shows spinal cord segments. THE SPINAL NERVES There are 31 pairs of spinal nerves. • 8 cervical spinal nerves (C01–C08) • 12 thoracic spinal nerves (T01–T) • 5 lumbar spinal nerves (L01–L05) • 5 sacral spinal nerves (S01–S05) • 1 coccygeal spinal nerve (coccygeal nerve) Spinal nerves "peek out" from between the vertebrae, through spaces called foramina.
The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae. This is true for all spinal nerves except for the first spinal nerve (pair), which emerges between the occipital bone and the atlas (the first vertebra).
Along the entire length of the spinal cord, spinal nerves arise at regular intervals and leave the vertebral column between the adjacent vertebrae through the intervertebral foramina.
Each spinal nerve is attached to the spinal cord by a ventral (anterior) and a dorsal (posterior) root. A very popular and useful chart, The Spinal Nerves illustrates the spinal nerves and pathways through the body.
The central illustration shows a posterior view of the spinal nerves exiting from the vertebral column and running throughout the body. Important skeletal structures are : $ The eleventh cranial nerve is the spinal accessory nerve.
This nerve is comprised of two parts—a cranial part and a spinal part. It is the spinal portion which is more clinically relevant. After emerging from either the cranial (at the nucleus ambiguus) or the spinal levels (C5–C6), the accessory nerve then passes into the jugular foramen.
"The Spinal Cord is an authoritative and detailed account of the development, organization and function of the spinal cord. Written by a series of experts, the book contains enlightening chapters that cover the anatomy and the architecture of the spinal cord in a clear and logical fashion.
Spinal nerves are an integral part of the peripheral nervous system (PNS). They are the structures through which the central nervous system (CNS) receives sensory information from the periphery, and through which the activity of the trunk and the limbs is regulated. Also they transmit the motor commands from the CNS to the muscles of the periphery.

The nerves connected to the spinal cord are the spinal nerves. The arrangement of these nerves is much more regular than that of the cranial nerves. All of the spinal nerves are combined sensory and motor axons that separate into two nerve roots.
Structure. The spinal nerves are relatively large nerves that are formed by the merging of a sensory nerve root and a motor nerve root. These nerve roots emerge directly from the spinal cord—sensory nerve roots from the back of the spinal cord and the motor nerve roots from the front of the spinal cord.
As they join, they form the spinal nerves on the sides of the spinal cord. The spinal nerves emanate from the spinal cord as pairs of nerves composed of both sensory and motor fibers that function as the intermediary between the central nervous system (CNS) and the periphery.
These mixed nerves that collectively transmit sensory, motor, and autonomic impulses between the spinal cord and the rest of the body.
In total, there are 31 pairs of spinal nerves, Author: Joshua T. Kaiser, Julian G. Lugo-Pico. Two spinal nerves branch off from the right and left sides of the spinal cord or the cauda equina at each spinal segment.
These spinal nerves are formed by 2 types of fibers—sensory fibers that send messages to the brain (feeling pain when the leg is hurt) and motor fibers that receive messages from the brain (lifting the leg to get out of a car).

Acupuncturists Carla Corkin, Lic. This book is a comprehensive illustrated surgical guide to operative exposures of the spinal nerves, also known as peripheral nerves. Each chapter is devoted to a particular nerve and describes the origin, anatomic relations, branches, surgical approaches, and clinical significance.
The last four cervical spinal nerves, C5 through C8, and the first thoracic spinal nerve, T1, combine to form the brachial plexus, or plexus brachialis, a tangled array of nerves, splitting, combining and recombining to form the nerves that subserve the upper limb region and upper back.
