The maxillary nerve is one of the branches of the trigeminal nerve, otherwise known as the fifth cranial nerve (CN V). Supplying sensory innervation to certain parts of the face, the mucosa of the nose, together with the teeth, this nerve allows you to feel that annoying fly landing underneath your eye or that annoying pain caused by your dentist. In neuroanatomy, the maxillary nerve ( V2) is one of the three branches or divisions of the trigeminal nerve, the fifth (CN V) cranial nerve.

The maxillary nerve is the second branch of the trigeminal nerve, which originates embryologically from the first pharyngeal arch. Its primary function is sensory supply to the mid-third of the face. In this article, we shall look at the anatomy of the maxillary nerve - its anatomical course, sensory and parasympathetic functions. Anatomical Course The maxillary nerve is the second of three branches of the trigeminal nerve. It arises between the trigeminal's ophthalmic and mandibular divisions in a region called the trigeminal ganglion, a cluster of nerves involved in relaying sensory information to the brain as well as chewing motor function. The maxillary nerve emerges from the anterior portion of the trigeminal ganglion, just inferior to the ophthalmic nerve. It runs anteriorly, passing through the lateral portion of the cavernous sinus until it reaches the foramen rotundum. It passes through the foramen rotundum to enter the upper pterygopalatine fossa. The maxillary nerve arises from the anterior convexity of trigeminal ganglion between ophthalmic and mandibular divisions of the trigeminal nerve. It is a medium-sized branch compared to the smaller ophthalmic nerve and the larger mandibular nerve.

This is the preview of our tutorial about the maxillary nerve, one of the trigeminal nerve's branches. Watch the full video about this essential nerve on htt. The maxilla, also known as the upper jaw, is a vital viscerocranium structure of the skull. It is involved in the formation of the orbit, nose and palate, holds the upper teeth and plays an important role for mastication and communication. The maxilla is the most important bone of the midface. It has a central location and provides structural support to the viscerocranium. It has functional and aesthetic significance as it has a fundamental role in facial architecture, separates the nasal and oral cavities, forms the upper jaw, and contains the maxillary sinus. [1] [2] Go to: Maxillary Nerve. The maxillary nerve, or second division of the trigeminal, is a sensory nerve that crosses the pterygopalatine fossa, traverses the orbit in the infraorbital groove and canal in the floor of the orbit, and appears upon the face at the infraorbital foramen as the infraorbital nerve.

As we've seen, the maxillary nerve runs forwards from the trigeminal ganglion, and enters the foramen rotundum, which is here. Here's the foramen rotundum in the dry bone. We'll go round to the outside to see where it emerges. Here it is, well hidden in the pterygo-maxillary fissure. The Maxillary Nerve [Vb; V2] (n. maxillaris; superior maxillary nerve), or second division of the trigeminal, is a sensory nerve. It is intermediate, both in position and size, between the ophthalmic and mandibular. It begins at the middle of the semilunar ganglion as a flattened plexiform band, and, passing horizontally forward, it leaves the skull through the foramen rotundum, where it.
Maxillary nerve is the 2nd division of trigeminal nerve. It is a pure sensory nerve. It commences from the anterior aspect of trigeminal ganglion. It passes along the lateral wall of the cavernous sinus. It then leaves the cranial cavity via foramen rotundum and enter pterygopalatine fossa. Maxillary nerve is the 2nd branch of the trigeminal nerve. INTRODUC. Let's learn the course and branches of the maxillary nerve in this video in a unique way.
Maxillary nerve (CN V2) Anatomy and function Kenhub
Treatment. The maxilla is a bone which helps to make up the skull. It is specifically located in the mid face, forms the upper jaw, separates the nasal and oral cavities, and contains the maxillary sinuses (located on each side of the nose. One of the maxilla's most important functions is to make up the architecture of our faces and to support. The maxillary nerve (CN V2, Latin: nervus maxillaris) is the second branch or division of the trigeminal nerve (CN V), also known as the maxillary division of the trigeminal nerve.
