When you stub your toe, you first feel a quick, sharp pain transmitted by , and then a moment later, a dull, throbbing pain transmitted by . A. A-delta fibers; C fibers B. A-delta fibers; thermoTRP receptors C. C fibers; thermoTRP receptors D. thermoTRP receptors; C fibers E. C fibers; A-delta fibers

The correct answer to the question is option A

A-delta fibers; C fibers

When you stub your toe, you first feel a quick, sharp pain transmitted by A-DELTA FIBERS, and then a moment later, a dull, throbbing pain transmitted by C FIBERS

A-delta fibers are sensory nerve fibers that stimulate pain receptors,they transmit sensory information while C fibers are class if fibers found in the somatic sensory system,they are afferent fibers that conveys input signals from the periphery to the central nervous system.

Explanation: When one stubs the toe,the second-fastest nerve fibers carry messages not from the touch receptors, but the pain receptors; that explains the sharp pain a split second after the thud. They cause what's called second pain, the throbbing pain you feel a few seconds after you stub your toe.

When the toe is stubbed,the impact is felt first before the pain, you're slamming it with a force that is equal to 2-3 times your body weight. (that's about the same force as a karate punch) since the toe has a tiny surface area, that force can't spread out. So the pain stays concentrated at the point of impact before pain is felt,this happens as a result of nerve fibers processing the painful stimuli which brings about that feelings/sensation of pain,and it reverts back after the painful stimulus has been removed.

Stubbing of the tie brings about throbbing toe pain, swelling and bruising.

i think its the first one
