The structure of the salivary gland of the moth (Manduca sexta)

Summary

The salivary glands of the moth,Manduca sexta, are described, emphasizing correlations between structure and function in an attempt to explain the production of a dilute saliva. Each of the paired glands consists of five distinct regions: protein secreting, fluid secreting, thin duct, bulbous duct, and common duct. Each region constists of a single, ultrastructurally distinct, cell type. It is proposed that the protein and fluid secreting regions produce an enzyme-containing primary saliva isosmotic with the haemolymph; this saliva is modified in the remaining regions of the gland to yield a dilute saliva.
