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.
How eye movement is affected depends on which nerve is affected. The eye is moved by three pairs of muscles, controlled by the 3rd, 4th, and 6th cranial nerves (see Third Cranial Nerve (Oculomotor Nerve) Palsy, see Fourth Cranial Nerve (Trochlear Nerve) Palsy, and see Sixth Cranial Nerve (Abducens Nerve) Palsy). These muscles move the eye up and down, right and left, and diagonally.
