Cranial Nerve III Oculomotor

The oculomotor nerve supplies the medial, superior, and inferior rectus muscles and the inferior oblique muscle, which control most eye movements. The third nerve also innervates the intrinsic muscles, controlling pupillary constriction and accommodation.

Extraocular muscle movements are discussed in Chapter 10. A patient with an oculomotor palsy is shown in Figure 10-144. The pupillary light reflex depends on the function of cranial nerves II and III (see Chapter 10). Visual fields are part of both the eye examination and the neurologic examination. The technique for visual field testing is discussed in Chapter 10.
