Fig. 18From: Reconstructing the neuromuscular ground pattern of phylactolaemate bryozoans: new data from the LophopodidaeHistological details on the apertural area of Lophopus crystallinus. A Lateral section of a retracted zooid showing numerous epidermal gland cells in the distal epidermis, and vestibular dilatators and duplicature bands connecting the distal body wall to the tentacle sheath. B Detail of the vestibulum showing epidermal gland cells in the vestibular wall and numerous granular glands. C–E Thick duplicature bands connect the body wall with the tentacle sheath, and thin vestibular dilatators are located more distally. b bud, cc coelom cavity, db duplicature bands, ed epidermis, egl epidermal gland cells, p peritoneum, t tentacle, ts tentacle sheath, vd vestibulum dilatators, ve vestibulum, vw vestibular wallBack to article page
