They then enter the alveolar canals on the infratemporal surface of the maxilla, and, passing from behind forward in the substance of the bone, communicate with the middle superior alveolar nerve, and give off branches to the lining membrane of the maxillary sinus and gingival and dental branches to each molar tooth from a superior dental ...
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.
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]
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.
The maxillary nerve (V 2) carries sensory information from the lower eyelid and cheek, the nares and upper lip, the upper teeth and gums, the nasal mucosa, the palate and roof of the pharynx, the maxillary, ethmoid and sphenoid sinuses and parts of the meninges.
The posterior superior alveolar nerve supplies the gingiva on the facial aspect of the maxillary molar teeth. The gingiva on the palatal aspect of the maxillary teeth is innervated by the greater palatine nerve apart from in the incisor region, where it is the nasopalatine nerve (long sphenopalatine nerve).
The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
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.
