The innervation of the wing membrane of Microchiroptera has been studied in three Bats (Rhinolophus hipposideros, Rhinolophus ferrumequinum and Miniopterus schrei-bersi); these species of Bats show a different kind of flight and a different morphological adaptation to flying. We have investigated the pattern of nerve supply in the wing membrane, the way the sensitive basketlike endings of nerve fibers associate together and the way they thicken in different areas of the wing membrane.
