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. 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 tracheal rings, (tracheal cartilages or C-shaped cartilaginous rings) vary from sixteen to twenty in number.he peculiar tracheal cartilages are the first and the last. The first cartilage is broader than the rest, and often divided at one end; it is connected by the cricotracheal ligament with the lower border of the cricoid cartilage, with which, or with the succeeding cartilage, it is sometimes blended.
