Sensory fiber with least conduction velocity:September. 2005: (A) C- fiber, (B) Alpha fiber, (C) beta fiber, (D) Gamma fiber
Answer is A. Ans. A: C- fiberAlpha fibers are the thickest (fiber diameter of 12-20 micrometer) and fastest conduction velocity (of 70-120 mis) whereas C-fibers are the thinnest (fiber diameter of 0.3-1.2 micrometer) and slowest conduction velocity (of 0.5-2 m/s)
