Asia Dermatomes Chart – A dermatome is the location of the skin of the human anatomy that is generally supplied by branches of a single back sensory nerve root. These spinal sensory nerves go into the nerve root at the spinal cord, 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 signs, touch, temperature) to the spine from specific locations of our anatomy.
Why Are Dermatomes Significant?
To understand dermatomes, it is essential to comprehend the anatomy of the spinal column. The spinal column is divided into 31 segments, each with a set (right and left) of posterior and anterior nerve roots. The kinds of nerves in the posterior and anterior roots are different. Anterior nerve roots are responsible 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 illustrate the sensory distribution of each dermatome across the body. Clinicians can examine cutaneous feeling with a dermatome map as a way to localise sores within central anxious tissue, injury to particular spine nerves, and to figure out the extent of the injury. Several dermatome maps have been established for many years but are typically conflicting. The most frequently used dermatome maps in major books are the Keegan and Garrett map (1948) which leans towards a developmental interpretation of this concept, and the Foerster map (1933) which associates much better with clinical practice. This article will examine the dermatomes using both maps, identifying and comparing the major differences between them.
It’s essential to stress that the existing Asia Dermatomes Chart are at best an estimation of the segmental innervation of the skin since the many locations of skin are typically innervated by a minimum of two spine nerves. For example, if a patient is experiencing tingling in only one location, it is unlikely that tingling would occur if only one posterior root is impacted because of the overlapping segmentation of dermatomes. A minimum of two neighboring posterior roots would require to be impacted for tingling to happen.

The Asia Dermatomes Chart typically play an important role in determining where the harm is originating from, giving medical professionals a tip regarding where to check for indications of infection, swelling, or injury. Common diseases that may be partly determined through the dermatome chart consist of:
- 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 methods and signs are crucial for recognizing injuries and diseases of the spinal column, including paralysis, bladder dysfunction, and gait disturbance, in addition to diagnostic procedures such as imaging (MRI, CT, X-rays looking for bone damage) and blood tests (to check for infection).
Dermatomes play a most important role in our understanding of the human body and can assist patients much better understand how problem to their back can be identified through various symptoms of discomfort and other odd or out-of-place feelings.Asia Dermatomes Chart
When the spine is damaged, treatments often include medication and intervention to decrease and fight swelling and rest, inflammation and workout to lower pain and strengthen the surrounding muscles, and in specific cases, surgical treatment to remove bone stimulates or fragments, or decompress a nerve root/the spinal cord.Asia Dermatomes Chart
