Inferior constrictor

Inferior Constrictor

The Inferior Constrictor is a muscle in the pharynx of the human body, part of the group of pharyngeal constrictor muscles. It is involved in the process of swallowing, helping to propel food and liquid from the mouth to the esophagus.

Anatomy

The Inferior Constrictor is the thickest and strongest of the three pharyngeal constrictor muscles. It originates from the thyroid cartilage and the cricoid cartilage, and inserts into the pharyngeal raphe in the posterior aspect of the pharynx.

Function

The primary function of the Inferior Constrictor is to constrict the pharynx during swallowing, helping to propel food and liquid from the mouth to the esophagus. It also helps to prevent air from being swallowed.

Clinical Significance

Damage to the Inferior Constrictor can result in dysphagia, or difficulty swallowing. This can occur due to nerve damage, muscle disorders, or structural abnormalities in the throat.
