title: Modulation of secretory activity in nucleus sacci vasculosi of Scylliorhinus canicula (L).
abstract: Data about the nervous regulation of secretion in nucleus sacci vasculosi of Scylliorhinus canicula are provided in the present study. The existence of cholinergic synapsis over secretory processes and electric synapsis among amyelinic fibers is shown. Likewise, images that demonstrate the existence of a type of merocrine secretion in which the secretory granules coming from the nucleus sacci vasculosi are emptied into the vessels, conserving their completeness while they pass through the pericapillary basal membrane are provided.
