-
Simplest receptors and common in epithelial tissue, responsible for sensation of itching
Free Nerve Endings
-
Small oval masses of flattened connective tissue cells in sheaths. 2 or more sensory fibers branch into each corpuscle and end within it as tiny knobs
Meissner's Corpuscles
-
Relatively large, ellipsoidal structures composed of connective tissue fibers and cells. Common in deeper dermal tissue of hands, feet, tendons.
Pacinian Corpuscles
-
Detect vibrations in tissue
Pacinian Corpuscle
-
Associated with changes at body surface. Include senses of touch, pressure, temp, and pain
Exteroreceptive Senses
-
Associated with changes in viscera
Visceroreceptive Sense
-
Associated with changes in muscles, tendons, and body position
Proprioceptive Senses
-
Most sensitive to temps between 10-20. Temps below 10 stimulate pain receptors, producing freezing sensation
Cold Receptor
-
Most sensitive to temps above 25 and become unresponsive at temps above 45. Cause burning sensation
Warm Receptor
-
Myelinated, conduct nerve impulses rapidly at velocities of 30m per second. Associated with sharp pain. Seldom continues after pain producing stimulus stops
Acute Pain Fibers
-
Unmyelinated, conduct impulses more slowly at velocities up to 2m per second. Cause dull aching pain sensation that may be diff to pin point
Chronic Pain Fibers
-
Pain that feels as if its coming from some other body part other then part that's being stimulated
Visceral Pain
