Three types of sensory neurons are found in the skin.

Aδ ("A-delta") fibers

These are thinly-myelinated.

They transmit signals in response to heat and touch. If the stimulus exceeds a certain threshold, the brain interprets these as acute pain. This is "good pain" because it warns you to do something to take care of the problems, e.g., a hot saucepan.

C fibers

These are unmyelinated and thus conduct impulses slowly.

C fibers also respond to heat and touch. If the stimulus exceeds a certain threshold, the brain interprets these as diffuse, dull, chronic pain. This is "bad pain" because it cannot be alleviated simply by removing the stimulus. It is pain generated by such things as damaged tissue or pain that remains after the stimulus that caused acute pain has been removed.

Aβ ("A-beta") fibers

These are thickly-myelinated fibers.

They mostly respond to painless stimuli such as light touch.

What controls sensation and glandular activity?

The autonomic nervous system controls both sensation and glandular activity. Sensory information is carried to the central nervous system via sensory nerves, while motor nerves regulate glandular activity, such as the secretion of hormones from glands.
