Abducens nerve

Strokes can be divided into two types: ischemic and hemorrhagic. In ischemic strokes, damage is caused by too little blood in the brain; in hemorrhagic strokes, by too much blood in the skull.

Your brain receives 20% of the blood that flows through your body. Disruptions to this flow cause brain damage, which is known as a stroke. High blood pressure can rupture blood vessels to the brain, causing damage to the surrounding brain tissue. Further, with interruption in the brain's circulation, the brain cells are starved of oxygen and nutrients and eventually die.

It really is a wonder drug for my Crohn's Disease, however the side effects are truly horrific: en.wikipedia.org/wiki/Prednisone#Side-effects

Three-dimensional visualization reconstructed from scanned human data. Superiolateral view of the right side of the optic pathway (colored) in a coronal section of the head; the left lobe of the brain is visible above the coronal section. Light enters the eye through the iris and is translated by specialized cells (rods and cones) that reside in the back of the retina into nerve impulses. These impulses travel from the optic nerve to the occipital lobe in the back of the brain via millions of bundled nerves in the white matter that make up the visual pathway. The white matter of the brain is made up of millions of nerve extensions (axons) which connect nerve fibers to other nerve fibers, target tissues, or organs. In addition to the nerves of the optic pathway, there are several different nerves that serve special functions of the structures associated with sight. The oculomotor, trochlear, and abducent nerves control voluntary movements of the eye muscles and eyelids, as well as controlling pupil dilation and lens focusing.
