Pain Corpuscles Deep Pressure Endings Temperature Somatosensation Pacinian

Text
Somatosensation:

1) pacinian corpuscles - deep pressure and vibration
2) meissner corpuscles - light touch
3) Merkle discs - deep pressure & texture
4) Ruffini endings - stretch
5) Free nerve endings - pain & temperature

6) Physiological zero - temperature of skin by which other temperatures are judged
7) gate theory of pain - gating mechanism turns pain signals on/off from spinal cord
8) Two point threshold - minimum distance between two detectable points
