Nerve Supply of Head and Neck. Each nucleus is associated with a cranial nerve (the oculomotor, facial, glossopharyngeal and vagus nerves) - these nerves carry the parasympathetic fibres out of the brain. otic,. The preganglionic parasympathetic fibers develop from the superior salivatory nucleus of the tractus solitarius in the pontine tegmentum and progress in the nervus intermedius before joining the facial nerve proper. Those ganglia can be found both in head and neck (and they are part of the cranial nerves) and in the trunk, close to the thoracic and abdominal/pelvic organs. The post-ganglionic fibres hitch-hike along these arteries (and their branches) in order to reach their target organs. Head and neck paragangliomas (HNPGLs) are rare tumors arising from nonsecretory head and neck parasympathetic ganglia.

Learn faster with spaced repetition. 2. Parasympathetic fibres2. Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system. Most are small terminal ganglia or intramural ganglia, so named because they lie near or within (respectively) the organs they innervate. The submandibular ganglion (or submaxillary ganglion in older texts) is part of the human autonomic nervous system.It is one of four parasympathetic ganglia of the head and neck. They account for 0.6% of head and neck tumors. The four parasympathetic ganglia of the head are related to three out of the four cranial nerves that have parasympathetic activities: the oculomotor (III), the facial (VII) and the glossopharyngeal (IX) nerves. Although they travel through the neck in the right and left vagi, they are destined for pulmonary, cardiac, oesophageal, gastric and intestinal targets: they synapse in minute ganglia in the walls of the viscera and do not innervate structures in the head and neck. Branches of the ciliary ganglion are named the short ciliary nerves while those of the pterygopalatine ganglion are termed the orbital, pharyngeal, palatine and . Beside above, where is a Postganglionic cell located? Each of the three ganglia are related to specific arteries in the head and neck. They are involved in parasympathetic control of the eye, major and lesser salivary glands and the lacrimal glands , and consist of the: (The others are the otic ganglion, pterygopalatine ganglion, and ciliary ganglion PLEASE COMMENT BELOW WITH CORRECT ANSWER AND ITS DETAIL EXPLANATION. The parasympathetic ganglia are a group of 4 bilateral automonic ganglia in the head and neck which receive parasympathetic fibers from the autonomic components of the cranial nerves III, VII and IX. (The others are the otic ganglion, pterygopalatine ganglion, and ciliary ganglion The exceptions are the four paired parasympathetic ganglia of the head and neck. Postganglionic fibers from the parasympathetic ganglia in head & neck reach the salivary and lacrimal glands , intraocular muscles via branches of trigeminal nerve. Located in the posterior of the orbit. It is almost of the size of head of a small pin. result from damage to the parasympathetic innervation of the mucous glands of the nose and the lacrimal gland.

The parasympathetic paraganglia are found almost exclusively in the head and neck along the branches of the glossopharyngeal and vagus nerves (Barnes et al., 2005). See Table 12-3 for a description of complications associated with head and neck injections. The greater petrosal nerve is a mixed nerve carrying parasympathetic, taste, and sensory fibers. •Make a list of cranial nerves having parasympathetic activity.
