Arachnoid cysts can be classified according to their location and by the type of tissue making up the cyst wall (arachnoid connective tissue or glioependymal tissue).
Animal tissues are classified into four main types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers body surfaces, lines body cavities, and forms glands. Connective tissue supports and binds other tissues together. Muscle tissue is responsible for movement, while nervous tissue is involved in transmitting electrical signals throughout the body.
