Summary: This article is dedicated to one of the controversial issues of modern anatomy - the issue of the participation of the trigeminal nerve innervation of the external muscles of the eye. Conducted by the author morphometric and experimental studies have shown that in the oculomotor nerve fibers is not sensitive to external eye muscles. This is confirmed by the absence of degeneration of sensory endings in those muscles by cutting the root of the trigeminal nerve in the rat. As a result, the author presented alternative scheme of the functional anatomy of the trigeminal nerve. However, the study has led to the need to raise the question of change in the classification of sensitivity, which would distinguish morphologically and functionally disparate devices innervation of muscle, teeth, periodontal dura.
Key words: trigeminal nerve, the trigeminal node branch of the trigeminal nerve, anatomy, proprioceptive sensitivity, proprioceptive innervation, external muscles of the eye.
