It provides [[Corpus:Sensory innervation|sensory innervation]] to parts of the [[Corpus:Maxillary sinus|maxillary sinus]] mucosa, [[Corpus:Gingiva|gingiva]], and [[Corpus:Molar (tooth)|molars]] by contributing to the [[Corpus:Superior dental plexus|superior dental plexus]].

The superior posterior alveolar nerve emerges as a single branch or in the form of two branches from the infraorbital nerve before the latter reaches the infraorbital sulcus. It descends at the maxillary tuberosity and gives off small branches to the neighbouring gingiva and buccal mucosa.
The superior posterior alveolar nerve typically emerges as a single branch or sometimes as two branches from the infraorbital nerve before it enters the [[Corpus:Infraorbital sulcus|infraorbital sulcus]]. It descends along the [[Corpus:Maxillary tuberosity|maxillary tuberosity]], giving off small branches that supply the adjacent gingiva and buccal mucosa.


Its fibres then run along the infratemporal surface of the maxilla into the maxillary alveolar canals, where they communicate with the superior median alveolar nerve. Together they form part of the superior dental plexus.
The nerve fibers then travel along the infratemporal surface of the [[Corpus:Maxilla|maxilla]], entering the [[Corpus:Maxillary alveolar canal|maxillary alveolar canals]], where they communicate with the [[Corpus:Superior middle alveolar nerve|superior middle alveolar nerve]], if present.

The posterior superior alveolar nerve innervates the molars. The mesiobuccal root of the first molar can also be supplied by the superior median alveolar nerve if it is present.
The superior posterior alveolar nerve primarily innervates the maxillary molars. In some cases, the mesiobuccal root of the first molar may also receive innervation from the superior middle alveolar nerve.

Definition

The superior posterior alveolar nerve is a branch of the infraorbital nerve. It provides sensory innervation to parts of the maxillary sinus mucosa, gingiva, and molars by contributing to the superior dental plexus.

Anatomy

The superior posterior alveolar nerve typically emerges as a single branch or sometimes as two branches from the infraorbital nerve before it enters the infraorbital sulcus. It descends along the maxillary tuberosity, giving off small branches that supply the adjacent gingiva and buccal mucosa.

The nerve fibers then travel along the infratemporal surface of the maxilla, entering the maxillary alveolar canals, where they communicate with the superior middle alveolar nerve, if present. Together, these nerves contribute to the formation of the superior dental plexus.

The superior posterior alveolar nerve primarily innervates the maxillary molars. In some cases, the mesiobuccal root of the first molar may also receive innervation from the superior middle alveolar nerve.
