Abstract:
The peritrophic membranes, which is several groups of animals are produced by midgut epithelia, have been investigated most thoroughly in insects. The following results concern Crustacea: In the peritrophic membranes chitin containing microfibrils are embedded in the ground substance consisting of proteins and mucopolysaccharides. In addition to a felt-like texture (Streuungstextur), microfibrils are arranged in textures of higher order (orthogonal texture — Gittertexture; hexagonal texture — Wabentexture).Inauguraldissertation der Math.-Nat.
