muscularis

It is characterized by deep folds into the muscularis propria.

The muscularis is often distorted or focally replaced by fibrosis.

Smaller tumors can usually be found to the muscularis propria layer of the intestinal wall.

The fluid is expelled under sympathetic contraction of the muscularis muscle coat.

Stage C1: Extending into muscularis propria but not penetrating through it.

Tissue necrosis extending into the submucosa and muscularis is probably the initial pathogenic event.

It consists of epithelium, lamina propria, and the muscularis mucosae.

The histologic findings of appendicits are neutrophils in the muscularis propria.

Tumor invades through the muscularis propria into pericolorectal tissues.

Basement membrane and muscularis mucosae are intact.

The duodenum wall is composed of a very thin layer of cells that form the muscularis mucosae.

(The muscularis externa of the duodenum is bounded by both tissue types.)

Its function is to innervate cells in the epithelial layer and the smooth muscle of the muscularis mucosae.

They migrate to the submucosa and muscularis mucosae and cause severe necrosis.

Tumor invades deep muscularis propria (outer half).

In the colon, for example, the muscularis externa is much thicker because the faeces are large and heavy, and require more force to push along.

In the gastrointestinal tract, the muscularis externa is bounded in most cases by serosa.

Attempts were made to measure the relative contribution to the overall metabolism of mucosa, lamina propria, and muscularis layers.

Muscularis (middle, muscle) layer.

The ova are initially deposited in the muscularis propria which leads to ulceration of the overlaying tissue.

Stage C2: Penetrating through muscularis propria.

The muscularis externa consists of an inner circular layer and a longitudinal outer muscular layer.

All biopsy specimens include muscularis mucosae; however only one contained sufficient submucosa for analysis of submucosal staining.

If the muscularis propria escapes extensive damage, we assume that the impaired bowel propulsion is allowed to recover to some extent.

The tela subserosa (or just subserosa) is a layer of tissue between the muscularis and serosa.
