  Epithelium \Ep`i*the"li*um\, n.; pl. E. {Epitheliums}, L.
     {Epithelia}. [NL., fr. Gr. 'epi` upon + ? nipple.] (Anat.)
     The superficial layer of cells lining the alimentary canal
     and all its appendages, all glands and their ducts, blood
     vessels and lymphatics, serous cavities, etc. It often
     includes the epidermis (i. e., keratin-producing epithelial


     cells), and it is sometimes restricted to the alimentary
     canal, the glands and their appendages, -- the term
     endothelium being applied to the lining membrane of the blood
