Article

Resume

Trois types de parois ont été décrits dans l'appareil circulatoire du tronc dePhoronis psammophila. La succession des diverses couches de chaque type est la suivante: 1. cellules “péritonéales” — lame basale — rares cellules endothéliales; 2. cellules myoépithéliales — lame basale — rares cellules endothéliales; 3. une couche de muscles circukires, puis une de muscles longitudinaux — épaisse lame basale — endothélium continu.

On the wall structure of the circulatory system inPhoronis psammophila Cori (Phoronida, Lophophorata)

Summary

Three types of wall structure of blood vessels have been described. It consists of the following distinct layers, from exterior to interior: 1. “peritoneal” cells — thin basal lamina — some endothelial cells; 2. myoepithelial cells resting on a basal lamina — some endothelial cells; 3. circular and longitudinal muscle layers of myoepithelial cells — thick basal lamina — continuous endothelial lining.
