The esophagus is a hollow muscular tube consisting of mucosa, submucosa, and muscularis layers. The esophagus lacks a serosal layer. The upper one third of the esophagus is striated muscle under voluntary control, and the distal two thirds of the esophagus is composed of smooth muscle under autonomic control.
What is the middle third of the esophagus? The upper third of the esophagus is composed of striated (voluntary) muscle. The middle third is a mixture of striated and smooth (involuntary) muscle, and the lower third consists only of smooth muscle. The esophagus has two sphincters, circular muscles that act like drawstrings in closing channels.
What are the three parts of the esophagus? There are three layers of the mucosa:
- The Epithelium: The inside of the esophagus is made up of cells called stratified squamous epithelium.
- The Lamina Propria: This is a layer of connective tissue just under the epithelium. This layer contains lymphocytes.
- Muscularis Mucosa: This is a layer of smooth muscle that is essential in helping nutrients flow into the submucosa.
What are the problems in the esophagus? Types of esophagitis
- Eosinophilic esophagitis. Eosinophilic esophagitis is caused by too many eosinophils in the esophagus.
- Reflux esophagitis. Reflux esophagitis is usually due to a condition known as gastroesophageal reflux disease (GERD).
- Drug-induced esophagitis.
- Infectious esophagitis.
What would cause a crooked esophagus? The precise causes of twisted esophagus are currently unknown. Through exploring and researching, medical science hopes to discover more information about this rare condition and to improve current treatment methods. The esophagus is a long, muscular tube which helps push food through the throat down into the stomach using a muscular action.

How do you clear a blocked esophagus?
