Detailed explanation-1: -The mucosa, or mucous membrane layer, is the innermost tunic of the wall. It lines the lumen of the digestive tract. The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.
Detailed explanation-2: -The lamina propria is composed of noncellular connective tissue elements, i.e., collagen and elastin, blood and lymphatic vessels, and myofibroblasts supporting villi. However, the main characteristic of the lamina propria is to contain numerous immunologically competent cells as well as nerve endings.
