Type of touch and pressure receptors found in epithelial tissues; responsible for the sensation of itching.
Free Nerve Endings
Type of touch and pressure receptors located in hairless portions of skin; involved in fine touch, as in distinguishing between two points on the skin.
Type of touch and pressure receptors located in deep subcutaneous tissues of some body parts; associated with heavier pressure, stretch, and vibrations.
Type of temperature receptors that respond to temperatures between 77° F and 113° F.
Type of temperature receptors that respond to temperatures between 50° F and 68° F.
Type of pain in organs resulting from the stimulation of mechanoreceptors and decreased blood flow with lower tissue oxygen levels and accumulation of pain stimulating chemicals.
Type of pain in which visceral pain may feel as if it is coming from some part of the body other than the part being stimulated; derived from common nerve pathways (ex: a heart attack may cause pain in the left shoulder).
Pain fibers that are myelinated; conduct impulses rapidly; associated with the sensation of sharp pain; sensed as coming from the surface.
Acute Pain Fibers
Pain fibers that are unmyelinated; conduct impulses slowly; associated with dull, aching pain sensations; felt in deeper tissues and skin.
