Overview. Coenzyme Q10 (CoQ10) is a substance that helps convert food into energy. CoQ10 is found in almost every cell in the body, and it is a powerful antioxidant. Antioxidants fight damaging particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death.
Chapter 4 - Extraocular movement. Eye movements are controlled by muscles innervated by cranial nerves III, IV and VI. In this chapter, the testing of these cranial nerves will be discussed. The most common symptom of damage to these nerves is double vision.
Disorders that directly damage cranial nerves include injuries, tumors, inflammation, infections (such as shingles), an inadequate blood supply (as occurs in diabetes), drugs, and toxins. Some cranial nerve disorders interfere with eye movement. Eye movement is controlled by 3 pairs of muscles. These muscles move the eye up and down, right and left, and diagonally. The muscles are controlled by the following cranial nerves: 3rd cranial nerve. 4th cranial nerve. 6th cranial nerve.
