-
hyperalgesia
a state of excessive sensitivity to pain at the site of an injury
-
Krause end bulb
globular nerve structure deep in skin, believed to be receptor for heat and cold, along with free nerve endings and capillary responses (also called Krause's corpuscle)
-
Meissner's (tactile) corpuscle
small oval body in corium (layer of skin below epidermis) with interlaced sensory fibrils and epithelioid cells believed to be receptors for light touch, along with free nerve endings
-
nociception
the peripheral and central nervous system processing of information about the external or internal environment related to tissue damage, including the quality, intensity, location and duration of stimuli
-
nociceptors
specialized peripheral receptors that signal actual or potential tissue damage by mechanical, thermal or chemical stimuli
-
nocioperception
the conscious interpretation of sensory information as unpleasant; the perception of pain

Pacinian corpuscle
oval sensory body located deep in subcutaneous layer; appears to be receptor for heavy pressure (also called lamellated corpuscle)
-
pain
an unpleasant sensory or emotional experience associated with actual or potential tissue damage
-
Ruffini corpuscle
oval sensory end structure in corium believed to be receptor for warmth; also seems to be function of free nerve endings and capillary responses
-
