For example, teeth on one side of the jaw can be numbed by injecting the mandibular nerve. Occasionally, injury or disease processes may affect two (or all three) branches of the trigeminal nerve; in these cases, the involved branches may be termed: V1/V2 distribution – Referring to the ophthalmic and maxillary branches
Visual area V2, or secondary visual cortex, also called prestriate cortex, [31] receives strong feedforward connections from V1 (direct and via the pulvinar) and sends robust connections to V3, V4, and V5. Additionally, it plays a crucial role in the integration and processing of visual information.
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.
Following is a list of cranial nerves responsible for sensation from the face: V1 (1st division of the trigeminal nerve) - associated with herpes zoster ophthalmicus; V2 (2nd division of the trigeminal nerve) V3 (3rd division of the trigeminal nerve)

V2 serves much the same function as V1, however, it also handles illusory contours, determining depth by comparing left and right pulses (2D images), and foreground distinguishment. V2 connects to V1 - V5. V3 helps process 'global motion' (direction and speed) of objects. V3 connects to V1 (weak), V2, and the inferior temporal cortex. [14] [15]
The ophthalmic nerve (CN V 1) is a sensory nerve of the head.It is one of three divisions of the trigeminal nerve (CN V), a cranial nerve.It has three major branches which provide sensory innervation to the eye, and the skin of the upper face and anterior scalp, as well as other structures of the head.
Russia said on Wednesday it had detained a man from Uzbekistan over the killing of a senior Russian general and his assistant in Moscow a day earlier. Lt. Gen. Igor Kirillov, who headed Russia’s ...
