Anatomical terms of muscle |
The trachealis muscle is a smooth muscle that bridges the gap between the free ends of C-shaped cartilages at the posterior border of the trachea, adjacent to the esophagus.[1]
The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force, e.g., during coughing.[1]
