title: Shell attachment in the pond snail Lymnaea stagnalis (L.)
abstract: The attachment of the body of the snail Lymnaea stagnalis to the shell was studied by histochemistry and light and electron microscopy. Muscles of the body wall insert into the connective tissue by way of long thin projections of sarcolemma. The muscle cells end under the basement membrane of a specialised area of the epidermis, the adhesive epithelium. The cells of this epithelium are filled with microfilaments and possess characteristic knob-like microvilli. The epithelium is attached to the sheel by way of an adhesive substance containing proteins and mucopolysaccharides.
