Injury anywhere affecting the cervical spinal column can disrupt nerve communication further down the spinal cord, sometimes resulting in paralysis or even death. The neck is unique in that it supports the weight of your head (10 to 11 pounds) and allows a variety of head/neck movement, such as turning your head from side to side, nodding, and looking up and down. Spinal nerves branch off from the spinal cord to innervate the rest of the body. Depending on the type of injury, associated symptoms may occur in the upper neck and/or in other areas of the body. Learn how 8 pairs of spinal nerves in the neck play an important role in sending messages to and from the spinal cord. In general, the cervical spinal nerves perform these functions including: C8 allows you to open and close your hands (hand grip) and gives you the ability to feel the outer (pinky) side of your hands and forearms. This is the most mobile section of your entire spine. © Working together, the atlas and axis are primarily responsible for spinal rotation, flexion (bend forward) and extension (bend backward). The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Each cervical nerve innervates or provides sensation (feeling) and motor function (movement) to both sides of a corresponding part of the upper body.

For example, the C5 dermatome is supplied by the C5 nerve root. Watch Now. The upper cervical spine is unlike any other part of the vertebral column. version.2020.05.028-2020.05.006, Ask questions and share your experiences in our new.  |  At vertebral levels of the spine, each disc functions to hold the upper and lower vertebrae together, absorb shock and allow some movement. A few examples of problems at this cervical level include: 1. In the cervical spine, there are eight pairs of spinal nerves labeled C1 to C8, which innervate the neck, shoulder, arm, hand, and more. Common disc disorders include degenerative disc disease and disc herniation that can cause spinal nerve impingement—sometimes called a “pinched nerve.” This can happen when a disc flattens (loss of disc height) or changes shape—the space for a spinal nerve passing through the neuroforamen is restricted. IL, Nerve compression may cause pain that radiates (travels) from the neck into the upper back and arm(s).

Problems at the C1-C2 vertebral levels may affect the vertebrae, the C2 spinal nerve, and/or the spinal cord. Any of these ‘common’ neck disorders can cause compression of the spinal cord resulting in cervical myelopathy. The C1 sits atop and rotates around C2 below. These nerves are vital to numerous functions in the head, shoulders, arms and trunk. Another similarity is the cervical intervertebral discs—between each level starting below C2 (axis). The spinal cord is protected by the C1-C2 vertebrae in the upper cervical area. If the spinal cord becomes compressed at the C2 level, it can cause pain, tingling, numbness, and/or weakness in the arms or legs, loss of bowel and/or bladder control, and other problems. If a cervical nerve becomes irritated or compressed, it may cause pain and/or dysfunction that correlates to its dermatome for sensations and/or myotome for motor control. The smaller foramens facilitate the passage of blood vessels around the spine. 60015. prime

Cervical trauma represents the most serious of the neck conditions a person may experience. See Spinal Cord Compression and Dysfunction from Cervical Stenosis. When the Vagus nerve is injured by compression caused by instability at C1-C2, this can cause vasospasms (narrowing of the arteries and reduction of blood flow).

Cervical spine anatomy illustrated. Photo Source: 123RF.com. When you need neck surgery for damaged cervical discs, one option is an artificial cervical disc. The C2 vertebrae is also called the Axis, and it’s the second one down in your neck. Whiplash Causes, Symptoms, Diagnosis, Treatment, 7 Meal Plan Tips for Spine Surgery Recovery, Sound Sleep Advice for a Healthy Spine Slideshow, C1, C2 and C3 provide motor function to the head and neck, as well as sensation from the top of your scalp to the sides of your face, C4 enables you to shrug your shoulders and automatically causes the diaphragm to contract when you are breathing. Head, face, upper neck, inner & middle ear, sympathetic nerve system, sinuses, eyes, auditory nerves … 1999-2020 Veritas Health, LLC. Severe cases of spinal cord injury at C2 can be fatal because breathing and other critical body functions may be impaired or stop.3 Paralysis of the body below the injured region of the spinal cord may also occur in some cases. Subluxations can cause interference to the nervous system at any point along the spine where the nerves exit. C1-C2 pain may either last for a short while or become chronic. The information is produced and reviewed by over 200 medical professionals with the goal of providing trusted, uniquely informative information for people with painful health conditions. These complex networks of nerves enable the brain to receive sensory inputs from the skin and to send motor controls for muscle movements.

More of the head’s rotational range of motion comes from C1-C2 than any other cervical joint.1. This option relieves symptoms associated with degenerative disc disease and maintains range of motion. Watch Cervical Spinal Cord Anatomy Animation. From there, the spinal nerve branches into a network of nerves that innervate its dermatome (for sensations) and myotome (for motor controls).  |  This condition is due to the high levels of motion within the C1-C2 joint. Cervical spinal nerves, also called cervical nerves, provide functional control and sensation to different parts of the body based on the spinal level where they branch out from the spinal cord. Sign up to receive free updates on back pain treatments, research, and doctor-reviewed spine health information. The C1-C2 vertebrae and spinal segment include the following structures: An injury to this nerve can cause problems in any part of its dermatome and/or myotome. See Leg Pain and Numbness: What Might These Symptoms Mean? Learn how 8 pairs of spinal nerves in the neck play an important role in sending messages to and from the spinal cord.

Upper and lower limbs being the most mobile and flexible parts of the body are served by cervical nerves and lumbar nerves respectively. Cervical C1 Vertebrae. C1 nerve exit the spinal column through the occiput and C1 vertebra; while C2 nerves exit the spinal column through the posterior arch of C1 vertebra and the lamina of C2 vertebra. Cervical spinal stenosis is a narrowing of the middle portion of the spinal canal and can lead to compression of the spinal cord. Watch: Spinal Motion Segment: C1-C2 (Atlantoaxial Joint) Animation. 1 The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head.

The spinal cord passes through the large, centrally placed vertebral foramen.
