Digestive Physiology: Motility and Histology

This lecture covers the characteristics of spontaneous electrical activity in smooth muscle cells of the digestive tract, the role of Cajal cells as pacemakers, slow waves in intestinal tone, and digestive contraction patterns. It also discusses swallowing, gastric accommodation, gastric motility, intestinal motility, colonic motility, and defecation mechanisms. Additionally, it explores the histological features of the tongue, salivary glands, and different segments of the digestive tract. The lecture delves into the anatomy of the rectum, anal canal, pelvic floor muscles, and pelvic openings, providing a comprehensive overview of digestive physiology and histology.
