Lower Pharynx Constrictor

The lower pharyngeal constrictor (lat. Musculus constrictor pharyngis inferior) is a muscle that is located in the lower part of the pharynx and is responsible for its narrowing. It consists of two parts - upper and lower. The upper part of the pharyngeal constrictor is located on the posterior wall of the pharynx, and the lower part is located on its anterior wall.

The function of the pharyngeal constrictor is to narrow the pharynx when swallowing food or liquid. This reduces the volume of the pharyngeal cavity and makes it easier for food or liquid to pass through the throat. In addition, the pharyngeal constrictor is also involved in the formation of the voice and provides its timbre and volume.

The pharyngeal constrictor consists of several muscle fibers that interconnect and form a dense bundle of muscles. It is surrounded by fascia and ligaments that provide stability and support.

With pathology, the pharyngeal constrictor can become damaged or inflamed, which leads to various diseases of the pharynx, such as pharyngitis, laryngitis or laryngotracheitis. In this case, you must consult a doctor for diagnosis and treatment.

Overall, the pharyngeal constrictor is an important muscle that plays an important role in the functioning of the pharynx. Knowledge of its anatomy and functions can help in understanding the functioning of the pharynx and its diseases, as well as in the treatment of these diseases.

**Pharynx constrictor inferior** is a muscle that is located in the lower part of the pharynx and is responsible for closing and limiting the diameter of the esophagus. The inferior constrictor is located in the vertebral region of the neck and is connected to other muscles of the neck. It consists of three bundles of muscle fibers that run towards the spine and connect into one
