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.
Together with the abducens nerve, the sixth cranial nerve, the trochlear nerve helps the eye move in a lateral (toward the midline) direction. The trochlear nerve controls the superior oblique muscle, which is one of the six extraocular muscles that influence eye movement.n other words, using the superior oblique muscles will cause the eyes to become crossed.. If the trochlear nerve is harmed, a condition called trochlear nerve palsy (or fourth nerve palsy) may result.
