The lamina propria , the delicate CT that fills the cores of the villi and the spaces between the crypts, is demarcated from the more peripheral layers by the muscularis mucosae, a thin band of smooth muscle which runs all the way around the mucosal layer and which sends strands up into the villi. It's believed these strands cause the villi to contract, expelling the contents of the crypts and the intervillous spaces. The muscularis mucosae is the outermost and last layer of the tunica mucosa of the intestine. The low power view above shows the general appearance of the duodenum. Only part of the tunica muscularis externa is visible in this field.
