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.
In neuroanatomy, the mandibular nerve (V 3) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only afferent fibers, the mandibular nerve contains both afferent and efferent fibers.
The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or "cutaneous") functions. [2] Adding to the complexity of this nerve is that autonomic nerve fibers as well as special sensory fibers ( taste ) are contained within it.
The nerves arise from the trunk of [citation needed] the maxillary nerve (CN V 2) within the pterygopalatine fossa [1]: 496 just before it enters the infraorbital groove. [citation needed] The nerve arises as a single trunk which split into 2-3 nerves within the pterygopalatine fossa. [1]: 496
The trigeminal ganglion is somewhat crescent-shaped, with its convexity directed anterolaterally. From its convex border arise the ophthalmic nerve (V 1), maxillary nerve (V 2), and mandibular nerve (V 3). [2] The ganglion receives, on its medial side, filaments from the carotid plexus of the sympathetic.
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
The anterior superior alveolar nerve (or anterior superior dental nerve) is a branch of the infraorbital nerve (itself a branch of the maxillary nerve (CN V 2)). [1] It passes through the canalis sinuosus to reach and innervate upper front teeth. Through its nasal branch, it also innervates parts of the nasal cavity.
The mental nerve is a branch of the posterior trunk of the inferior alveolar nerve. This is a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). [1] It emerges from the mental foramen in the mandible. [2] It divides into three branches beneath the depressor anguli oris muscle.
