Answer:
Delta fibers.
Explanation:
Myelinated fibers may be defied as the fibers that are covered by the myelin sheath. Three different classes of nerve fibers are group A nerve fibers, B fibers and C fibers.
Delta fibers are the type of group A fibers. These fibers are involved in the transmission of the acute pain information. The information is transferred from the sensory fibers to the central nervous system. These delta fibers can carry information faster and they are larger than the C fibers.
Thus, the correct answer is delta fibers.
