Final answer:

C-fibers have slower nerve conduction due to being thin and unmyelinated compared to A-fibers, which are myelinated and conduct signals faster.


Explanation:

C-fibers are slow-conducting unmyelinated thin sensory afferents with a diameter of 1 µm and a conduction velocity of approximately 1 m/s. These fibers transmit signals related to pain and gentle touch. In contrast, A-fibers, which are myelinated, have larger diameters and thicker myelin sheaths, leading to faster conduction speeds.
