These are more numerous in the neck than in any other part of the gland ; at the fundus they are few and far between, whereas at the neck they form almost a continuous layer. Their protoplasm is densely reti- culated. 267. The pyloric glands (Fig. 115).âThe duct of each pyloric gland Fig. 115.âFrom a Vertical Section is several times longer than in the peptic. The duct of the former occupies some places as much as half of the thickness of the mucosa, whereas that of the latter does not exceed in the fundus of the stomach or in the cardia, more than one-fourth or one-fifth of the thickness. The epithelium lining the duct of the pyloric glands is the same as in that of the peptic.
