Abstract
The innervation of the division zone in the asexually reproducing Microstomum lineare (Turbellaria) was studied by light and electron microscopy. Nerve fibres presumed to be peptidergic form a circumferential belt and longitudinal nerve fibres and nerve swellings join the circumferential belt from opposite directions. Peptidergic nervous influence on asexual reproduction by paratomy is indicated by (1) synaptoids and (2) omega-shaped configurations. These release sites are observed at muscles of the division zone and in the vicinity of neoblast cells.
