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.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

the index of refraction of the second medium is higher. i just took the test trust me !
