Résumé
ChezEuspongia officinalis, l'acetylcholine et l'adrénaline agissent comme excitateurs des contractions spontanées, localisées et brèves, et favorisent en outre l'extrusion des glycoprotéines contenues dans les cellules contractiles. Na+ et Ca++ sont nécessaires au fonctionnement des pacemakers.
