Question

The inner layer of oesophageal wall consists of longitudinal muscles.

• A. True
• B. False

Answer 1

The correct option is B False

The wall of oesophagus is made up of two types of smooth muscles. The inner layer is made up of circular muscles and the outer layer is made up of longitudinal muscles. The rhythmic contraction and relaxation of these muscles is called peristalsis. Perisitalsis helps to push the food in forward direction towards the stomach.
