SENSE OF HEARING : STRUCTURE OF COCHLEA. 7G5 Fig. The outer surface of the head of the inner rod is hollowed for the receptionof the head of the outer rod, and a long process is given off which runs out-wards. On either side of the rods are situated various cells; above, andclosely adherent to them, is the menibrana reticularis, and above this is thethick membrana tectoria. The length of the rods is graduated, and rangesfrom 1-150th of an inch at theapex of the spiral to l-500th inchat its base, the length of the outerrods increasing more rapidly thanthat of the inner. The hair cellsare very delicate, columnar inform, with large round nuclei andnucleoli; the rest of their contentsis finely granular. From each oftheir flat summits a row of fourbristles or cilia project. There arefour rows of hair cells—one (e,Fig. 279) situated internally to therods, the other three (/*) externallyto them. The lower ends of the Seetion through one of the coi]s of the eoMea:_s T> hair cells are evenly r
