30 paź 2023 · The maxillary nerve (CN V/II) supplies the anterior and superior nasopharynx, while the tonsillar nerves carry fibers from both the glossopharyngeal nerve (CN IX) and the vagus nerve (CN X). The motor branches come from the pharyngeal plexus and carry fibers from the vagus nerve (CN X).

30 paź 2023 · They are all innervated by the pharyngeal plexus and pharyngeal branch of the vagus nerve, except the stylopharyngeus which is innervated by the glossopharyngeal nerve. Functions: They all act on the pharynx, either constricting or elevating it.
1 maj 2023 · The pharyngeal muscles have a high nerve-muscle fiber ratio of 1:2 to 1:6 which allows for precisely coordinated pharyngeal functions. The innervation of the cricopharyngeus muscle is from the pharyngeal plexus and the recurrent laryngeal nerve.
25 maj 2024 · The pharyngeal plexus, formed by branches of cranial nerves IX and X, supplies motor and sensory innervation to the pharynx. Cranial nerve X is the principal motor nerve for the pharyngeal muscles, contributing through its pharyngeal branches.
24 lip 2023 · The muscles of the pharynx receive motor (efferent) supply from the ninth and tenth cranial nerves. The stylopharyngeus muscle is the only muscle supplied by the glossopharyngeal nerve. The vagus nerve supplies all other muscles, which will be listed later.
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.
3 lis 2023 · The motor innervation for the muscles of the soft palate comes from the pharyngeal plexus derived from the vagus nerve (CN X). The only exception is the tensor veli palatini muscle which is supplied by the medial pterygoid nerve, a branch of the mandibular division of the trigeminal nerve .
