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.
The oculomotor nerve controls several muscles of the eye. As with all parasympathetic cranial nerves, its signals originate in the brain cells, or neurons, in the brainstem and travel down long, thin extensions called nerve fibers.These nerve fibers connect with their target organ.f all the parasympathetic cranial nerves, the vagus nerve, which contains about 80 percent of all parasympathetic fibers in the body, is the most important.
