Chemoreceptors
-
Also called "nociceptors"
Pain Receptor
-
Sensory nerve ending that conducts impulses interpreted to pain
Pain Receptor

In certain blood vessel walls, stimulated by changes in pressure
Baroreceptor
-
Responds to a change in length or volume
Stretch Receptor
-
Sensitive to light energy
Photoreceptor
-
Occurs when sensory neurons reach threshold and the resulting action potentials cause the brain to become aware of that event
Sensation
-
Occurs when brain interprets those sensory impulses
Perception
-
Pain is the sensation, but "realizing" you stepped on a tack is the __________.
Perception
-
