(28) These previous studies along with the present study suggest that mechanoreceptive trunk responses to slow vertebral movements (0.5mm/s) are neither affected by acute single facet joint dysfunction nor by high velocity low amplitude spinal manipulation regardless of ramp amplitude.
Functionally, the labial sensilla are classified into two categories: mechanoreceptive and chemoreceptive sensilla, within which there can be determined twenty-four types (21 types of mechanosensilla, three types of chemosensilla) on the basis of their external appearance and location.
Each pacifier dome array type was designed to provide the infant with cutaneous stimulation localized to different soft tissue regions of the oral apparatus known to contain high densities of A[beta] mechanoreceptive afferents.
A experiment whit with glutamate (nociceptive agent) into the rat masseter muscle demonstrated evoked activity in AS mechanoreceptive afferents that were shown to project to the caudal brain stem, a region documented to be a critical relay of nociceptive input form jaw muscles as well as other craniofacial tissues (CAIRNS et al., 2001).
Although pharyngeal dilator muscle responsiveness is likely impaired during NREM and REM sleep (90), the genioglossus can respond to both sustained mechanoreceptive (negative pressure) and chemoreceptive stimuli, particularly when combined stimuli are present (91).
campaniform sensilla, spines and hairs16 have been previously reported which were contact chemoreceptors and having mechanoreceptive neuron in addition to chemoreceptive function.
In some studied groups such as the Micropterigidae and the Heterobathmiidae which are spore/pollen feeders, the long maxillary palpi possess sensilla which are supposed to have both a prehensile and a mechanoreceptive role.

The third type, high-threshold mechanoreceptive nociceptors, are unresponsive to heat stimuli.
For example, chronic excessive afferent impulses from acute and chronically stressed (or traumatized) mechanoreceptive, proprioceptive and nociceptive fibers in and around the spinal column (joints, articular capsules, muscles, ligaments, tendons, discs, etc.) may initiate pathologic spinal cord reflexes in motor and sympathetic efferents.
