1. A simple, isolated preparation is described in which the activity of the longitudinal muscle of the anterior mesenteric artery of the domestic fowl is recorded isotonically.2. The longitudinal muscle of the anterior mesenteric artery exhibited tone and marked spontaneous activity. Maximal shortening of this muscle was equal to about 60% of its resting length.3. Acetylcholine in low concentrations produced powerful contractions of the muscle, whereas low concentrations of catecholamines… CONTINUE READING
