The pharyngeal nerve is a small branch of the maxillary nerve (CN V 2), [1]: 496 arising at the posterior part of the pterygopalatine ganglion. It passes through the palatovaginal canal [1]: 370, 496 with the pharyngeal branch of the maxillary artery. [1]: 508
The pharyngeal branch of the vagus nerve is the principal motor nerve of the pharynx. It represents the motor component of the pharyngeal plexus of vagus nerve and ultimately provides motor innervation to most of the muscles of the soft palate (all but the tensor veli palatini muscle), and of the pharynx (all but the stylopharyngeus muscle). [1]
The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity. The pharyngeal muscles (involuntary skeletal) push food into the esophagus.
It has the following components: [2] Motor – pharyngeal branch of vagus nerve (CN X) which arises from the superior portion of the inferior ganglion of vagus nerve, with the neuron cell bodies of its axons residing in the nucleus ambiguus. The pharyngeal branch ramifies upon reaching the superior border of the middle pharyngeal constrictor ...
The pharyngeal part is supplied by the glossopharyngeal nerve and the oral part is supplied by the lingual nerve (a branch of the mandibular branch (V3) of the trigeminal nerve) for somatosensory perception and by the chorda tympani (a branch of the facial nerve) for taste perception. Both parts of the tongue develop from different pharyngeal ...
The pharyngeal veins commence in the pharyngeal plexus superficial to the pharynx. The pharyngeal veins receive as tributaries meningeal vein, and the vein of the pterygoid canal. The pharyngeal veins typically empty into the internal jugular vein (but may occasionally instead empty into the facial vein, lingual vein, or superior thyroid vein). [1]
Pharyngeal branch can refer to any one of several different structures near the pharynx: Nerves Pharyngeal branch of vagus nerve - "ramus pharyngeus nervi vagi" Pharyngeal branches of recurrent laryngeal nerve - "rami pharyngei nervi laryngei recurrentis" Pharyngeal branches of glossopharyngeal nerve - "rami pharyngei nervi glossopharyngei"
