Question

List the correct sequence of the wall in the alimentary canal from deep to superficial. Option 1: Serosa, Mucosa, Submucosa, Muscularis Option 2: Muscularis, Serosa, Submucosa, Mucosa Option 3: Submucosa, Serosa, Mucosa, Muscularis Option 4: Mucosa, Submucosa, Serosa, Muscularis

Answer 1

Option 4: Mucosa, Submucosa, Serosa, Muscularis

Step-by-step explanation:

The correct sequence of the wall in the alimentary canal from deep to superficial is Option 4: Mucosa, Submucosa, Serosa, Muscularis. This order is based on the layers of the wall that make up the alimentary canal. The mucosa is the innermost layer and is made up of epithelial cells that are responsible for absorption and secretion. The submucosa is beneath the mucosa and contains connective tissue, blood vessels, and nerves. The serosa is the outermost layer and is made up of connective tissue, which helps to protect and support the alimentary canal. The muscularis is the layer beneath the serosa and consists of smooth muscle that is responsible for propulsion and movement of food.
