(9) The responses of Aurelia medusae to pharmacological agents and ionic variation were classified into four response types: Type I, no response; Type II, inhibition of pacemaker activity; Type III, inhibition of both pacemakers and swimming muscles; and Type IV, increase in pacemaker output.
(10) In portal hypertension, three types of cutaneous portosystemic collaterals may develop: the 'classical' caput Medusae, enterostomal varices and scar or adhesion-related abdominal collaterals.
