Some of these fibres form the striae acousticae. The third group of cells (C, Fig. 46) forms the vestibular ganglion in the fundus or floor of the internal auditory meatus. Its cells send efferent fibres to the utricle, external and superior semicircular canals, and afferent fibres which form the mesial root of the auditory nerve. This root passes beneath the restiform body (Fig. 46) to terminate in the nerve cells of the acoustic tubercle and trigone in the floor of the 4th ventricle. These nerve cells and fibres are in no sense auditory, but con- cerned with the balancing of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Keith, Arthur, Sir, 1866-1955.
