The three muscle layers in the stomach's mascularis externa.
Explanation:
The stomach has four layers in their wall; The mucosa which is the inner lining of the stomach that secretes hydrochloric acid. The submucosa made of connective tissues, nerve fibres and blood vessels. The mascularis externa, made of 3 muscle layers responsible for contraction and parastalsis. The outer fibrous membrane or layer called serose.
