Pharyngeal plexus of vagus nerve. Muscles of the pharynx, viewed from behind, together with the associated vessels and nerves. (Pharyngeal plexus visible but not labeled.) The pharyngeal plexus is a nerve plexus located upon the outer surface of the pharynx. It contains a motor component (derived from the vagus nerve (cranial nerve X)), a ...
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).

The muscle is divided into four parts according to its four distincts origins: a pterygopharyngeal, buccopharyngeal, mylopharyngeal, and a glossopharyngeal part. The muscle inserts onto the pharyngeal raphe, and pharyngeal spine. It is innervated by pharyngeal branch of the vagus nerve via the pharyngeal plexus.
The musculus uvulae [1] (also muscle of uvula, uvular muscle, or palatouvularis muscle [2]) is a bilaterally muscle of the soft palate (one of five such muscles) that acts to shorten the uvula when both muscles contract. [3] It forms most of the mass of the uvula. [2] It is innervated by the pharyngeal plexus of vagus nerve (cranial nerve X ...
Dissection of the muscles of the palate from behind. The salpingopharyngeus muscle is a muscle of the pharynx. It arises from the lower part of the cartilage of the Eustachian tube, [1] and inserts into the palatopharyngeus muscle by blending with its posterior fasciculus. It is innervated by vagus nerve (cranial nerve X) via the pharyngeal plexus.
FMA. 46727. Anatomical terms of muscle. [edit on Wikidata] The levator veli palatini (/ lɪˈveɪtər ˈviːlaɪ ˌpæləˈtaɪnaɪ /) is a muscle of the soft palate and pharynx. It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus. During swallowing, it contracts, elevating the soft palate to help prevent food from ...
The superior laryngeal nerve is a branch of the vagus nerve. It arises from the middle of the inferior ganglion of the vagus nerve and additionally receives a sympathetic branch from the superior cervical ganglion. The superior laryngeal nerve produces two branches: the internal laryngeal nerve (its sensory branch) which supplies sensory fibers ...
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. There are two muscular layers of the pharynx: the outer ...
