Abstract:
:The loci of calcium distribution in Nereis pharyngeal visceral muscle have been examined by cytochemical precipitation using potassium pyroantimonate. In Na-, Ca- and Mg-free media, pyroantimonate incubation was used to pinpoint loci of intracellularly bound calcium. This method also revealed heavy deposition on the inner face of the plasma membrane, in the sarcoplasmic reticulum and nucleus. X-ray microprobe analysis of the precipitate confirmed the presence of calcium and antimony peaks. It is concluded that the plasma membrane may constitute a major calcium pool for the activation of contraction in this muscle.
