Question

What is the primary type of body tissue which makes up your esophagus?

Answer 1

The esophagus consists of three principle layers: the mucosa, submucosa and muscularis.

The mucosa consists of non-keratinized stratified squamous epithelium, lamina propria (areolar connective tissue) and muscularis mucosae (smooth muscle). Near the stomach the mucosa also contains mucus glands. This provides a protective layer to the esophagus.

The submucosa consists of areolar connective tissue, blood vessels and mucus glands. This provides a loose connection between the mucosa and muscularis.

The muscularis consists of two layers: internal circular muscles and external longitudinal fibers. This provides propulsion. It should be noted that muscularis is covered by the adventitia, an areolar connective tissue that merges with the connective tissue of surrounding tissues, as opposed to serosa like the stomach, small and large intestines
