Mucous Cell Types in the Major and Minor Salivary Glands of the Japanese Macaque

Abstract

Summary. The authors investigated mucous cells in the major and minor salivary glands of the Japanese macaque and concluded the following:
1. Submandibular gland: The mucous acini of this gland are of type II (containing neutral and weak acid mucopolysaccharides).
2. Sublingua l gland: The mucous acini of this gland are composed of two types, with type II outnumbering type I (containing neutral, weak and strong acid mucopolysaccharides).
3. Minor sublingual glands: The mucous components of this gland include two types, with type I greatly outnumbering type II.
4. Upper, lower labial, buccal and palatine glands: All of the mucous acini of these glands are of type I.
5. Retro m olar glands; The mucous acini definitely surpass the seromucous ones in number, and type I greatly outnumbers type II.
6. Glands in the root of the tongue: The mucous components of these glands include two types, with type I greatly outnumbering type II.
7. Mucous glands neighboring the glands of von Ebner: These glands are composed of two types, and both types almost equal in number.
