APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The submucosa is a thick layer of loose connective tissue that surrounds the mucosa. This layer also contains blood vessels, lymphatic vessels, and nerves. Glands may be embedded in this layer.

Detailed explanation-2: -Submucosa. This second layer supports the mucosa. It is rich in blood vessels, lymphatic vessels, and nerves.

Detailed explanation-3: -Four-layered (mucosa, submucosa, muscularis mucosa, and serosa) organization of the digestive tract.

Detailed explanation-4: -In the gastrointestinal tract, the submucosa is the layer of dense irregular connective tissue or loose connective tissue that supports the mucosa. It also joins the mucosa to the bulk of underlying smooth muscle (fibers running circularly within layer of longitudinal muscle).

Detailed explanation-5: -Lamina propria-In addition to loose connective tissue, the lamina propria contains numerous blood and lymphatic vessels that transport nutrients absorbed through the alimentary canal to other parts of the body.
