Cervical Spine Dermatome Chart – A dermatome is the area of the skin of the human anatomy that is primarily provided by branches of a single spinal sensory nerve root. These spine sensory nerves go into the nerve root at the spine, and their branches reach to the periphery of the body. The sensory nerves in the periphery of the body are a type of nerve that transmits signals from sensations (for instance, pain symptoms, touch, temperature level) to the spine from particular locations of our anatomy.
Why Are Dermatomes Important?
To understand dermatomes, it is very important to understand the anatomy of the spinal column. The spinal column is divided into 31 sections, each with a set (right and left) of posterior and anterior nerve roots. The kinds of nerves in the posterior and anterior roots are various. Anterior nerve roots are accountable for motor signals to the body, and posterior nerve roots get sensory signals like pain or other sensory signs. The posterior and anterior nerve roots combine on each side to form the spinal nerves as they exit the vertebral canal (the bones of the spinal column, or backbone).

Dermatome maps
Dermatome maps portray the sensory distribution of each dermatome throughout the body. Clinicians can evaluate cutaneous experience with a dermatome map as a method to localise lesions within central nervous tissue, injury to particular back nerves, and to figure out the extent of the injury. Numerous dermatome maps have actually been developed for many years but are often conflicting. The most commonly utilized dermatome maps in major books are the Keegan and Garrett map (1948) which leans towards a developmental analysis of this concept, and the Foerster map (1933) which associates much better with clinical practice. This article will examine the dermatomes using both maps, recognizing and comparing the major differences between them.
It’s very important to tension that the existing Cervical Spine Dermatome Chart are at best an estimation of the segmental innervation of the skin since the many areas of skin are typically innervated by at least two spinal nerves. For instance, if a patient is experiencing tingling in only one location, it is not likely that feeling numb would occur if only one posterior root is impacted because of the overlapping division of dermatomes. A minimum of two neighboring posterior roots would require to be impacted for feeling numb to happen.

The Cervical Spine Dermatome Chart typically play a vital role in finding out where the problem is coming from, giving medical professionals a tip regarding where to check for indications of infection, swelling, or injury. Typical illness that might be partially determined through the dermatome chart include:
- Spinal injury (from a fall, etc.)
- Compression of the spinal cord
- Pressure from a tumor
- A hematoma (pooling blood)
- Slipped or bulging discs
A series of other analysis devices and symptoms are very important for recognizing injuries and illness of the spine, including paralysis, bladder dysfunction, and gait disruption, along with diagnostic procedures such as imaging (MRI, CT, X-rays looking for bone problem) and blood tests (to look for infection).
Dermatomes play a necessary role in our understanding of the body and can help patients much better understand how problem to their back can be determined through numerous symptoms of pain and other weird or out-of-place feelings.Cervical Spine Dermatome Chart
When the spine is harmed, treatments often include medication and intervention to minimize and fight swelling and rest, inflammation and exercise to minimize pain and strengthen the surrounding muscles, and in specific cases, surgery to get rid of bone spurs or pieces, or decompress a nerve root/the spine.Cervical Spine Dermatome Chart
