[{'content': 'A “Potential Anastomosis” seen in \nSelect and explain. \nA. Labial branch of facial artery, B. Intercostal artery, C. Coronary artery, D. Arterial arcades of mesentery', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Arterial anastomosis is the communication between the arteries, or branches of arteries. It may be actual or potential.\n\nActual Arterial Anastomosis:\xa0In actual arterial anastomosis the arteries meet end to end. For example, palmar arches, plantar arch, circle of Willis, intestinal arcades, labial branches of facial arteries.\nPotential Arterial Anastomosis:\xa0In potential arterial anastomosis the communication takes place between the terminal arterioles. Such communications can dilate only gradually for collateral circulation. Therefore on sudden occlusion of a main artery, the anastomosis may fail to compensate the loss. The examples are seen in the coronary arteries and the cortical branches of cerebral arteries.', 'role': 'assistant'}]
