MUSCULUS TRACHEALIS Meaning and
Definition
-
Musculus trachealis, commonly known as the tracheal muscle, is a band of smooth muscle fibers that encircles the posterior aspect of the trachea. It is a vital component of the respiratory system and plays a crucial role in controlling airflow during respiration.
The musculus trachealis is responsible for regulating the diameter and tension of the trachea, contributing to airway resistance and controlling airflow. By contracting or relaxing, it can adjust the size of the lumen of the trachea, thereby altering the resistance to airflow. This is particularly important during forced exhalation, where the contraction of the muscle narrows the trachea and increases the velocity of the air, effectively aiding in the expulsion of air from the lungs.
Located between the ends of the tracheal cartilages, the musculus trachealis is highly elastic, allowing it to contract and expand in response to varying respiratory demands. It is also innervated by the autonomic nervous system, specifically the parasympathetic fibers, which regulate its contraction and relaxation.
The contraction of the musculus trachealis can be influenced by various factors, such as the stimulation of the parasympathetic nervous system or the presence of irritants in the airways. For example, during an asthma attack, the musculus trachealis may contract excessively, leading to bronchoconstriction and causing difficulty in breathing.
In summary, the musculus trachealis is a smooth muscle band that encircles the trachea and plays a crucial role in regulating airflow by adjusting the diameter of the tracheal lumen. Its contraction and relaxation are controlled by the autonomic nervous system, and it is essential for maintaining proper respiratory function.

Etymology of MUSCULUS TRACHEALIS
The word "musculus trachealis" is derived from Latin.
The term "musculus" translates to "muscle" in English, referring to a bundle of muscle fibers.
"Trachealis" is derived from the Latin word "trachea", which means "windpipe". It refers to the structure in the respiratory system that connects the larynx to the bronchi. The suffix "-alis" in Latin implies "pertaining to" or "related to".
Therefore, "musculus trachealis" can be understood to mean "muscle of the windpipe" or "windpipe muscle" in English. The term specifically refers to the smooth muscle found in the trachea, which acts to contract or relax, allowing for changes in the size and shape of the windpipe during breathing.
