The postganglionic fibers join branches of the mandibular nerve (primarily the auriculotemporal and buccal nerves) to supply the parotid gland and nearby mucous glands with secretomotor
fibers and also supply the vasculature with vasodilator fibers.
and vasodilator neurons regulate fluid and molecular exchange between gut lumen, tissue, and vasculature.
In the rat jejunum, for instance, mast cells released mediators in response to sensitized antigen and evoked secretomotor
responses, which were suppressed by tetrodotoxin, indicating neural involvement .
Innervation of the parasympathetic component increases the secretomotor
function, and innervation of the sensory component regulates the sensitivity of the nasal mucosa [4, 9].
Stylopharyngeus muscles are supplied by the motor component, and the parotid gland is supplied by the parasympathetic secretomotor
Aside from the direct effect of [H.sub.2]S on ion channels and transporters within the epithelium, exogenous [H.sub.2]S indirectly stimulates chloride secretion by activating secretomotor
neurons in human and guinea pig colon mucosa/submucosa preparations  (Figure 3).
* Sialorrhea: Botulinum toxin can block cholinergic parasympathetic secretomotor
fibers of the salivary gland.
It supplies efferent vasodilator fibers to the tongue and secretomotor
fibers to the salivary glands in the floor of the mouth and parotid gland.
Furthermore, CRF peptides can reproduce secretomotor
and mucosal alterations in vitro.
Previous findings reveal that IBS-D patients showed an increase in mast cell density (Park et al., 2006) which can facilitate the release of inflammatory mediators causing disturbances to the epithelial barrier, and alterations in secretomotor
The parasympathetic portion of the nervus intermedius originates in the superior salivatory nucleus in the dorsal pons and provides the secretomotor
function of the ipsilateral lacrimal gland, submandibular glands, sublingual glands, and minor salivary glands.
The chorda tympani is a mixed sensory and secretomotor
branch of the facial nerve.
