submucosa

Examples of submucosa in the following topics:

• Submucosa

  • The submucosa is a dense irregular layer of connective tissue with large blood vessels, lymphatics, and nerves that supports the mucosa.
  • From the inside out they are called: mucosa, submucosa, muscularis, and serosa .
  • The submucosa is relatively thick, highly vascular, and serves the mucosa.
  • The absorbed elements that pass through the mucosa are picked up from the blood vessels of the submucosa.
  • The submucosa also has glands and nerve plexuses.

• Histology of the Small Intestine

  • The small intestine wall has four layers: the outermost serosa, muscularis, submucosa, and innermost mucosa.
  • The muscularis is a region of muscle adjacent to the submucosa membrane.
  • The submucosa is the layer of dense, irregular connective tissue or loose connective tissue that supports the mucosa, as well as joins the mucosa to the bulk of underlying smooth muscle.
  • The jejunum and ileum do not have Brunner's glands in the submucosa, while the ileum has Peyer's patches in the mucosa, but the duodenum and jejunum do not.
  • This image shows the layers of the duodenum: the serosa, muscularis, submucosa, and mucosa.

• Muscularis

  • From the inside out they are called the mucosa, submucosa, muscularis externa, and serosa.
  • It should not be confused with a thin layer of muscle known as the muscularis mucosa, which lies within the submucosa, a layer of tissue adjacent to the muscularis externa.
  • The muscularis mucosa is adjacent to the submucosa, and should not be confused with the muscularis externa.

• Epithelial Membranes

  • The submucosa is the tissue that connects the mucosa to the muscle outside the tube.

• Mucosa

  • From the inside out they are called: mucosa, submucosa, muscularis, and serosa.

• Diverticular Disease

  • Diverticulosis, also known as diverticular disease, is the condition of having outpocketings of the colonic mucosa and submucosa due to weaknesses of muscle layer in the colon wall.
  • Diverticulosis as seen endoscopically, showing characteristic diverticula in the colon, which are outpocketings of the colonic mucosa and submucosa through weaknesses in the muscle layers in the colon wall.

• Microscopic Anatomy of the Stomach

  • The submucosa lies under this and consists of fibrous connective tissue that separate the mucosa from the next layer, the muscularis externa.
