Human anatomy, including structure and development and practical considerations . lar fibres, and {b) a smallermass of cells which lies above the larger one and partly to the inner and partly to the outer sideof the tract of the vestibular fibres. The apex of the large triangular mass approaches themid-line and its superior and inferior basal angles are prolonged upward and downward alongthe vestibular tract. When examined microscopically the large mass is found to include three subdivisions : (a)a tapering caudally directed nucleus which continues the inferior angle along the descendingvestibular root, {b) an extended triangular nucleus that includes the greater part of the largemass and (r) an irregular pyramidal nucleus that prolongs upward the superior angle. The firstof these subdivisions (rt) is known as the spinal vestibular nucleus (niic. spinalis n. vestibularis), the .second i^b) as the median vestibular nucleus (nuc. mediali.-i n. vestibularis). also as the chiejnucleus or the triangular nucleus and the third {c) as tiie superior vestibular nucleus or the.
