In the many-layered epithelia the cuticle has lost its importance, and it is cither an inconspicu- ous boundary line or is entirely absent. Glandular Epithelium.—Glandular epithelium is distinguished physiologically from ordinary pavement epithelium by the fact that it also produces secretions or excretions; anatomic:il]y it is recognizable by the presence of ' gland cells," cells which carry on tlie secretion and, to a greater or less extent, reveal their character by their structure. Ciharactcristic glandular cells are, for example,.
