Ultrastructure of the innervation of inner tentacles in Lingula anatina.
(A) The latero-abfrontal neurite bundle consists of neurites of large diameter (ln). (B) Several neurite bundles (nb) are located along the frontal side of inner tentacle. (D) Subperitoneal neurites (spn) are located between coelothelial cells (cc) of tentacles and connective tissue (ct). Abbreviations: c2, tentacular coelom; sv, synaptic vesicles.
