GENERAL HISTOLOGY

Detailed explanation-1: -Mucosa is the soft tissue that lines the body’s canals and organs in the digestive, respiratory and reproductive systems. It’s also called the mucous membrane. Mucosa has three layers: epithelium, lamina propria and muscularis mucosae.

Detailed explanation-2: -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-3: -The lamina propria, a thin layer of connective tissue, is part of the mucosa. Here is an example of the mucosa of the mouth. The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa.

Detailed explanation-4: -Most mucous membranes contain stratified squamous or simple columnar epithelial tissue. The epithelial tissue sheet lies directly over the layer of loose connective tissue called lamina propria.

Detailed explanation-5: -Stratified squamous nonkeratinizing epithelium lines the lumen of the esophagus. This type of epithelium is found in mucous membranes.
