Abstract
The regulation of body-wall muscle contraction in the ascidian Styela rustica was studied. Acetylcholine (ACh, 1–10 μM) induced a significant contraction of isolated muscle strips. The ACh-induced contractile response was potentiated and prolonged in the presence of proserine (15 μM), which confirms acetylcholinesterase activity in the S. rustica body-wall muscle. Atropine (1–100 μM, M-cholinoreceptor blocker) did not prevent the ACh-induced contractile response, while d-tubocurarine (1–100 μM, N-cholinoreceptor blocker) progressively reduced muscle contraction induced by 10 μM ACh. Thus, neuromuscular transmission in the S. rustica body-wall muscle is mediated by nicotinic-like ACh-receptors. Procaine reduced ACh-induced (10 μM) muscle contraction. As well, our experiments showed spontaneous rhythmic contractile activity in isolated muscle strips of S. rustica. Atropine, d-tubocurarine, procaine, and proserine did not alter rhythmic activity. Myogenic automaticity is suggested as a possible cause of the rhythmic contraction of the ascidian body-wall muscle.
