The oculomotor system is composed of six extraocular muscles attached to the orbit and to the eyeball, extraocular motor neurons located in three different brainstem motor nuclei, and premotor centres and circuits involved in the generation and control of the different types of eye movement. Its precise functional design and robust biomechanics have allowed this motor system to survive, almost unchanged, across different trends in vertebrate evolution.
