Neuropeptides released from activated nociceptive afferent nerves play a pivotal role in inflammatory reactions and pain, significantly modulate cardiac, vascular, respiratory, gastrointestinal and immune functions and influence the protective, restorative and trophic Occlusions that result from abnormal mandibular positioning are reported to play a role in posture regulation, balance control, and oculogyric stabilization. This effect can be attributed to the projection of dento-muscular joint afferent neurons of the masticatory system to the accessory nerve nucleus responsible for motor control of the

The role of visceral afferent nerves in cardiac arrhythmias. By Frank Lorenz Pettinga. Abstract. Thesis (M.A.)--Boston University, This item was digitized by the Internet Archive Publisher: Boston University. Year: OAI identifier: oai: Visceral pain fibers that utilize the pelvic splanchnic nerves (S2 to S4) are said to enter not the dorsal roots of these spinal nerves but rather their ventral roots.

By entering the ventral roots, these visceral pain fibers have less contact with somatic afferent fibers; therefore, there is less referred ://   Afferent Stimuli. Visceral afferent fibers responsive to mechanical stimuli are either high or low threshold with the high threshold endings frequently serving as nociceptors.Low threshold mechanosensitive receptors respond to changes in stress or strain and provide information relevant to digestion (gut), cardiac filling or function (cardiac veno-atrial, atrial and ventricular).

The afferent fibers of first-order taste neurons (special visceral afferent [SVA/VA]) innervating oropharyngeal taste buds travel in the facial (VII), glossopharyngeal (IX), and vagus (X) nerves (Fig.

The central nerves are localized within the brain and spinal cord, while peripheral nerves include visceral efferent fibers and visceral sensory afferent fibers, forming the visceral motor nerve and visceral sensory nerve, ://   These “gut peptides” or “reproductive hormones” have been localized within nuclei responsible for the relay of visceral afferent information to the forebrain.

The presence of peptides and hormones along the gut- or heart-brain continuum suggests that these neurochemicals do more than modulate the visceral processes of digestion and ?. The afferent fibers originated from visceral organs travel in sympathetic and parasympathetic nerves and transmit information to the central nervous system about activities of the organ or the occurrence of tissue injury, the latter through nociceptive fibers.

These signals also generate autonomic reflexes which allow regulation of organ :// The book deals with the neural integration of behavioral and physiological aspects of bodily homeostasis viewed from the standpoint of the lower brainstem, particularly the medulla oblongata.

An historical framework is maintained. Functions covered include breathing, regulation of arterial pressure and blood flow to the tissues, arousal and nociception, and eating and :// Because of this role as a major pathway of information transfer from inner organs to the central nervous system, an involvement of the vagus in visceral pain has also been suggested.

However, results in this regard are conflicting and hence a vagal contribution to visceral pain is still contentious [ 12 ].
