Physiology of Smooth Muscles and Digestive System - Part 2

Explore the second part of this 30-minute NPTEL-NOC IITM lecture on the physiology of smooth muscles and digestive system. Delve into the detailed anatomy of the gastrointestinal tract, including its "tube in a tube" structure, peritoneal cavity, and smooth muscle organization. Learn about the myenteric plexus, serosa, syncytium formation, and gap junctions that characterize digestive smooth muscles. Understand the innervation patterns of smooth muscles, the role of acetylcholine, and the differences between single and multi-unit smooth muscles. Examine stress-relaxation properties unique to smooth muscles, actin-myosin interactions, and the membrane potential characteristics of intestinal muscle tissue.
