A literature survey is provided summarizing the available information on exocrine epidermal glands that produce adhesive secretions in insects. The focus is on both the ultrastructure of the gland cells and the identity and function of the chemical secre
Enteroendocrine cells secrete hormones that influence gut function. Some have a free apical surface while others do not contact the gut lumen. Their secretory granules are accumulated in the basal cytoplasm, since these cells exocytose their secretory product through the basal membrane. Gastrin, a ...
