No decussation between the nerves of opposite sides takes place in the medulla oblongata, but commissural fibres pass between the two nuclei (Kolliker). Further, numerous fibres from the opposite pyramidal tract enter the nucleus and end in connexion with its cells. The nucleus is thus brought into connexion with the motor area of the opposite side of the cerebral cortex. Nervus Accessorius.—The accessory nerve also is a motor nerve, and it is generally described as consisting of a spinal and a cerebral or accessory part. The spinal part of the nerve emerges by a series of roots which issue from the surface of the lateral column of the superior part of the spinal medulla as low down as the fifth cervical nerve. These take origin in a column of cells situated in the anterior column of gray matter of the spinal medulla, close to its lateral margin, and Fasciculus gracilis Fasciculus cuneatus Entering posterior nerve- root Fig. 528.—Diagram of the Spinal Origin of the Accessory Nerve (after Bruce)..
