Corpus: Middle superior alveolar nerve: Unterschied zwischen den Versionen

The '''superior middle alveolar nerve''' is a branch of the [[Corpus:Infraorbital nerve|infraorbital nerve]]. Its branches extend into the [[Corpus:Superior dental plexus|superior dental plexus]] and provide sensory innervation to parts of the [[Corpus:Maxillary sinus|maxillary sinus]] mucosa, as well as the [[Corpus:Premolar (Tooth)|premolars]] and occasionally the mesiobuccal root of the first [[Corpus:Molar (tooth)|molar]].

The superior middle alveolar nerve branches off from the [[Corpus:Infraorbital nerve|infraorbital nerve]] between the exits of the [[Corpus:Posterior superior alveolar nerve|posterior superior alveolar nerve]] and the [[Corpus:Anterior superior alveolar nerve|anterior superior alveolar nerve]]. It communicates with both neighboring nerves and forms the superior dental plexus. The nerve may be absent, in which case its area of innervation is covered by the posterior superior alveolar nerve.
