• normal adequate stimulus - displacement of tooth

? Force or movement?

Periodontium is viscoelastic - force and displacement vary in health and disease.

respond to tension rather than compression (cf. Ruffini)

• Man can detect forces of 0.5gm (1-2g), displacements 2- 5µm

• Project to V ganglion or V MSN - ?significance

  V ganglion _V sensory n. _sensation?
  
  V MSN _ V motor n. _ reflex control of jaw muscles?
