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 trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
Its name (trigeminal, from Latin tri- 'three' and -geminus 'twin' [1]) derives from each of the two nerves (one on each side of the pons) having three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve ...
This disorder is characterized by episodes of severe facial pain along the trigeminal nerve divisions. The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected.

Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
“Some body fat is visible as subcutaneous fat just below the skin, while other body fat surrounds our organs and is used to sheath nerves and the brain,” explains John Martinez, M.D., a sports ...
Intradural procedures, such as removal of a brain tumour or treatment of trigeminal neuralgia via a microvascular decompression, require that an incision is made to the dura mater. To achieve a watertight repair and avoid potential post-operative complications, the dura is typically closed with sutures .
