The cranial nerves:
Cranial nerves (cranial):
Is 12 nerve, and medical students to memorize their names and not just in numbers, even if it cost him an effort it is inevitable that because it is the basis for understanding the disease in the head and neck.
Cranial nerves III graduated from the front of the brain stem brainstem nerve except the fourth (Bakri open Alaba) that comes out from the back of the brain stem and then wraps up to the front of the brain stem.
First nerve: olfactory Olfactory:
Amralasb olfactory perforated plate bone Almnkhala. Nerve cell bodies are not in the brain but in the mucous membrane lining of the nose and sending nerves (graduated from the cell body to reach cell to another) is up nerves to the Olfactory bulb.

optic
nerve: It is in fact prolong the brain more independent, which is the nerve
center. The
optic nerve on each side of the head arises from the optic stalk and is
surrounded by three volumes that envelop the brain.
Place entering the optic nerve in the eye called optical disk optic disc. If increased pressure inside the head, the optical disk will be affected and you will get the changes papilloedema. Because the optic nerve is in fact part of the brain and not raw like the rest of it if nerves where the damage occurred, it will reconstitute itself as do the remaining nerves.If left optic nerve of the eye, it will go through the optic canal in the skull optic canal and which also contain the ophthalmic artery. Then meet nerves from both sides and Vicuan intersection optic optic chiasma. Here it is important to know that nerve fibers in the optic nerve, which is located on the the temporal fibres Foreign remaining nerve that runs on the outside, and the fiber that runs in the internal nasal fibers, they go to the second any left side to the right - and right to left.Fiber in the third-party receives from the inner side of the eyeFiber in the internal receive the image on the outer side of the eyeAfter the intersection out optic tract.

If damage to the optic tract in one of the points of the head, the man will get him: homonymous hemianopia.
