Question

are narrow-diameter, unmyelinated sensory nerve fibers that transmit signals from pleasant touch. A. P tactile efferents B. C tactile efferents C. P tactile afferents D. PT nerves E. C tactile afferents

Answer 1

Option E, C tactile (CT) afferent

Step-by-step explanation:

Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).

C-Tactile afferents (CTs) are unmyelinated mechanoreceptors of low threshold and low conduction velocities.

In humans, CT neurons are found in hairy skin.

The pleasant feeling observed during a slow gentle touch is due to the interaction of

CT neurons project to the insular cortex in the brain

Hence, option E is correct
