QuestionChoice
A-alpha fibres carry proprioception signals. These are myelinated and thus the conduction speed is fast. In fact, they have the quickest conduction speed of all the nerve fibres listed.

A-delta fibres carry pain (mechanical and thermal) signals. These are myelinated and thus the conduction speed is much quicker than C fibres, which also carry these signals, but are non-myelinated. A-delta fibres also have a much larger diameter than C fibres, allowing signals to be transmitted quicker along the nerve fibre.

C fibres carry pain (mechanical, chemical and thermal) signals. These are non-myelinated and thus the conduction speed is much slower than A-delta fibres, which also carry these signals, but are myelinated. C fibres also have a much smaller diameter than A-delta fibres.

You are cooking a meal and, as you are very busy, you turn around and catch your hand on the edge of the frying pan. You feel a sharp, sudden, intense pain.

What nerve fibre is responsible for transmitting this signal?
