<prompt> Which of the nerve fiber carry pain:A-AlphaA-BetaA-GammaC-fibers  <response>: Ans. D C-fibersRef: Gationg, 25th ed. pg. 94; Guyton Physiology, 11th ed. pg. 576-577 Pain is carried by A d and C fibres General classification of Nerve Fibers In the general classification, the fibers are divided into types A, B and C. Type A fibers are further subdivided into abg and d fibers. Type A fibers are the typical large and medium-sizec myelinated fibers of spinal nerves. Type B fibres are Myelinated, Pre-ganglionc autonomic Type C fibers are the small unmyelinated nerve fiber: that conduct impulses at low velocities.Nerve Fibre Type and FunctionFiber typeFunctionA fiber aProprioception; Somatic motorbTouch, pressure, motorgMotor to muscle spindledPain, cold, touchB fiberPreganglionic AutonomicC fiber Dorsal rootPain, temperature, reflex responsesSympathetic rootPostganglionic sympathetic
