It is about seven or eight inches (ca. 18-20 cm.) in length. Its axial direction is chiefly dorso-ventral, but it inclines forward to a variable extent and somewhat medially in its ventral part; the ventral end, which is at the reticulo- omasal orifice, is about an inch (ca. cm.) in front of the plane of the cardia and to the right of the median plane. The groove is twisted in a spiral fashion, so that its thickened edges or lips project first backward, then to the left, and finally for- wartl. The twist involves chiefly the left lip, and the relative position of the lips is reversed at the ventral end. The mucous membrane on the lij^s of the a'sojjh- ageal groove is brown and wrinkled, like that of the atrium; in the bottom of the. \ Fig. 391.—0m.\sum of Ox, Sagittal Sectiox; Right View. js orders; 5, muscular pillar; 6. neck connecting with reticulum; 7, connection with groove it is pale, like that of the oesophagus, marked by longitudinal folds, and pre- sents pointed, horny papillae on its ventral part. In the reticulum the mucous membrane is raised into folds about half an inch liigh, which enclose four-, five-, or six-sided spaces or cells (Cellulae reticuli); this l)ecuUar arrangement suggested the scientific name and also the popular term "; These cells are subdivided by smaller folds, and the bottoms are studdetl with pointed, horny papillae. The cells grow smaller and gradually dis- appear near the a?sophageal groove and the edge of the rumino-reticular fold; an inch or two from the latter the mucous membrane has the pajiillary arrangement of the rumen. At the reticulo-omasal orifice there are peculiar homy papillae, which are curved and resemble the claws of a small liird; hence they are termed unguliform (Papillae unguliformes).
