... Two types of axons carry painful sensations: Type A and Type C fibers. 1. Myelinated Type A fibers carry sensations of fast pain, or prickling pain, such as that caused by an injection or deep cut. These sensations reach the CNS very quickly and often trigger somatic reflexes. They are also relayed ...

Some of these axons could be seen leaving the spinal cord white matter and projecting into gray matter. Although it could not be determined whether these ...
