In neuroanatomy, the maxillary nerve (V 2) is one of the three branches or divisions of the trigeminal nerve, the fifth (CN V) cranial nerve.It comprises the principal functions of sensation from the maxilla, nasal cavity, sinuses, the palate and subsequently that of the mid-face, [1] and is intermediate, both in position and size, between the ophthalmic nerve and the mandibular nerve.
It branches from the infraorbital nerve within the infraorbital canal [1] [2] at around the midpoint of this canal and enters the canalis sinuosus.It passes through towards the nose before passing inferior-ward and ramifying [2] into branches which innervate the upper/maxillary incisor and canine teeth; [1] [2] it usually innervates all the anterior teeth.
The posterior superior alveolar nerves (also posterior superior dental nerves or posterior superior alveolar branches [citation needed]) are sensory branches of the maxillary nerve (CN V 2). They arise within the pterygopalatine fossa as a single trunk. They run on or in the maxilla.
The superior dental plexus is a nerve plexus that innervates the upper/maxillary teeth and as adjacent structures. [1] It is formed by the anterior superior alveolar nerve (ASAN), middle superior alveolar nerve (MSAN), and the posterior superior alveolar nerve (PSAN). [1] [2] [3] It issues dental branches and gingival branches. [4]
The inferior alveolar nerves supply sensation to the lower teeth, [2]: 519 and, via the mental nerve, sensation to the chin and lower lip. [ citation needed ] The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric .
The middle superior alveolar nerve or middle superior dental nerve is a nerve that drops from the infraorbital portion of the maxillary nerve to supply the sinus mucosa, the roots of the maxillary premolars, and the mesiobuccal root of the first maxillary molar.
The infraorbital nerve is a branch of the maxillary nerve (CN V 2), itself a branch of the trigeminal nerve (CN V); [2] it may be considered as the terminal branch of the maxillary nerve. [3] It arises from the maxillary nerve in the pterygopalatine fossa. [2]
The maxillary second molar is the tooth located laterally from both the maxillary first molars of the mouth but mesially from both maxillary third molars. This is true only in permanent teeth. In deciduous teeth, the maxillary second molar is the last tooth in the mouth and does not have a third molar behind it.
