GENERAL HISTOLOGY

Detailed explanation-1: -Megaesophagus may be caused by any disease which causes the muscles of the esophagus to fail to properly propel food and liquid from the mouth into the stomach (that is, a failure of peristalsis).

Detailed explanation-2: -Achalasia is a primary esophageal motility disorder characterized by the absence of primary peristalsis and a failure of the lower esophageal sphincter to relax, resulting in a dilated esophagus. Dysphagia is the classic and most common symptom.

Detailed explanation-3: -Peristalsis squeezes your esophageal muscles from top to bottom. This pushes food and liquid along. If you could see peristalsis, it would look like a wave passing down your esophagus. To keep food and liquids moving in the right direction, your digestive tract has special muscles along its course called sphincters.

Detailed explanation-4: -Abdominal pain, chest pain or back pain. Chronic cough or sore throat. Difficulty swallowing or feeling like food is stuck in your throat. Heartburn (burning feeling in your chest). Hoarseness or wheezing. Indigestion (burning feeling in your stomach). More items •10-Aug-2021
