It constricts the tracheal lumen, causing air to be expelled with more force. This is helpful in coughing and yelling.
When the trachealis muscle contracts, it reduces the diameter of the trachea, helping to regulate airflow and adjust resistance in the respiratory system. This action can be particularly helpful during activities that require increased respiratory effort, such as exercise or periods of high air demand like during coughing or sneezing.
When a muscle contracts, it shortens in length.
The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force e.g. during coughing.
The main function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force while you are coughing. This muscle is smooth and is located adjacent to the esophagus.

When one muscle in a pair contracts the other expands.
The trachealis muscle is located on the posterior side of the trachea and allows the esophagus to expand anteriorly during swallowing.

When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
