The nasopharynx is lined by respiratory epithelium that is pseudostratified, columnar, and ciliated. Polyps or mucus can obstruct the nasopharynx, as can congestion due to an upper respiratory infection. The auditory tube, which connects the middle ear to the pharynx, opens into the nasopharynx at the pharyngeal opening of the auditory tube ...
Innervation of the nasal cavity responsible for the sense of smell is via the olfactory nerve, which sends microscopic fibers from the olfactory bulb through the cribriform plate to reach the top of the nasal cavity. General sensory innervation is by branches of the trigeminal nerve (V 1 and V 2): Nasociliary nerve (V 1)
The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
The plexus provides motor innervation to most muscles of the soft palate (all but the tensor veli palatini muscle) and most muscles of the pharynx (all but the stylopharyngeus muscle). [1] The larynx meanwhile receives motor innervation from the vagus nerve (CN X) via its external branch of the superior laryngeal nerve and its recurrent ...
Receives motor innervation by Vagus nerve (CN X). Stylopharyngeus receives motor innervation by Glossopharyngeal (CN IX) Identifiers; Latin: musculi pharyngis, musculus constrictor pharyngis or tunica muscularis pharyngis: MeSH: D010609: TA98: A04.2.06.001: TA2: 2176: FMA: 67169: Anatomical terms of muscle
The levator veli palatini (/ l ɪ ˈ v eɪ t ər ˈ v iː l aɪ ˌ p æ l ə ˈ t aɪ n aɪ /) is a muscle of the soft palate and pharynx.It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus.
The superior pharyngeal constrictor muscle receives motor innervation from the pharyngeal plexus ... domain from page 1143 of the 20th edition of Gray's Anatomy (1918)
The mucous membrane receives sensory [citation needed] innervation from the posterior ethmoidal nerve (branch of the ophthalmic nerve (CN V 1)) and from branches of the maxillary nerve (CN V 2). [5] Postganglionic parasympathetic fibers of the facial nerve that synapsed at the pterygopalatine ganglion control mucus secretion. [citation needed]
