Résumé

Nous avons examiné les connexions neuro-musculaires des muscles lisses dans le canal déférent du Rat blanc. Nous avons observé des connexions neuro-musculaires avec spécialisation des membranes apposées dans la zone de contact. Dans la plupart des cas la spécialisation des membranes dans la zone de contact se traduit par des épaississements symétriques de matériel électroniquement dense liés aux membranes opposées. Dans certaines des connexions les épaississements accusent une certaine asymétrie, dont l'interprétation peut être discutée.

Summary

Neuromuscular relations in smooth muscle layers of the vas deferens of the albino rat were investigated. In certain neuromuscular contacts membrane specialization have been described in most cases consisting of symmetrical “thickenings” by apposition of an electron dense material to each membrane. Sometimes, the thickenings show an asymmetrical position. The significance of this finding is discussed.
