Control of Visually Guided Eye Movements
A. The Classification of Eye Movements
As shown in Figure 2
each eye has 6 extraocular muscles, the four recti and the two obliques.
The eye muscles are innervated by three cranial nerves, the 3rd, 4th and
6th. The cell bodies of these nerves reside in the corresponding brainstem
nuclei, the oculomotor, the trochlear and the abducens.
