The rest of the rod is a slender, more or less cylindrical, piece—the body. The outer rod is larger and longer than the inner, the latter being slightly bent in the middle. Owing to the position of the rods, the two files form an arch— the arch of Corti. Between it and the corresponding part of the basilar membrane is a space—the tunnel of the arch, triangular in cross-section. 479. The substance of the rods, or pillars, of Corti is bright, highly refractive, and slightly and longitu- dinally striated. The head of the inner rod is triangular, a short process extending inwards towards the inner hair-cell, a long process extending outwards over the head of the outer pillar. Outwards, the triangular head possesses a concave surface grasping the convex surface of tiie head of the outer rod. This latter.
