They play an important role in the control system by sensing defects that occur during essential processes such as DNA replication or chromosome segregation, and inducing a cell cycle arrest in response until the defects are repaired.

<span>A delta fibers can rapidly transmit pain information to the brain because alpha delta fiber is a type of sensory nerve fiber.
Aδ fibers carry cold, pressure and some pain signals.
Because Aδ fibers are thinly myelinated, they send impulses faster than unmyelinated C fibers, but more slowly than other, more thickly myelinated "A" class fibers.</span>
