Neurons in the Skin That are Responsible for Detecting Pain

Question

Neurons in the skin that are responsible for detecting pain are
A) apolar.
B) pseudo-unipolar.
C) bipolar.
D) multipolar.

Accepted Answer

Neurons responsible for detecting pain are sensory neurons or nociceptors. These are usually pseudo-unipolar in structure, meaning that they have a single axon that divides into two branches, one going towards the peripheral tissue and the other towards the spinal cord. They have no dendrites and are thus classified as unipolar, but they function like bipolar neurons with two axonal branches.
