Micromorphology and histochemistry of polysaccharides in the goat mandibular salivary gland.

The micromorphology and histochemistry of mucosubstances in mandibular salivary gland of goat were studied. Encapsulated ganglia were present in the interlobular connective tissue giving nerve fibres to the ducts and blood vessels therein. The mandibular gland of goat was a mixed tubuloacinar gland possessing mucous tubules and acini, the latter capped by seromucous demilunes. The mucous secretory units contained high amounts of neutral and acidic sulfated mucosubstances. The seromucoid demilunes contained neutral and less acidic nonsulfated mucosubstances. No glycogen was found in both types of secretory cells.
