Definitions:

Fast Fibers

Sensory receptors in skin, muscles, organs, and membranes around both bones and joints; these myelinated fibers quickly convey intense sensory input to the brain, where it is perceived as sharp, immediate pain.

Slow Fibers

Sensory receptors in skin, muscles, organs, and membranes around both bones and joints; these unmyelinated fibers slowly convey intense sensory input to the brain, where it is perceived as chronic, dull, steady pain.

Throbbing Pain

A type of pain experience characterized by a pulsating or beating sensation, often associated with headaches or injuries.

Somatosensory Cortex

A region of the brain that processes sensory input from various parts of the body.
