The Middle Constrictor Muscle is a muscle in the pharynx that plays a crucial role in the process of swallowing. It is one of the three constrictor muscles of the pharynx, the others being the superior and inferior constrictor muscles.

Anatomy

The Middle Constrictor Muscle is located between the superior and inferior constrictor muscles. It originates from the stylohyoid ligament and the lesser and greater cornu of the hyoid bone, and inserts into the median fibrous raphe at the back of the pharynx.

Function

The primary function of the Middle Constrictor Muscle is to constrict the pharynx during swallowing, propelling the food bolus from the mouth to the esophagus.

Clinical Significance

Damage to the Middle Constrictor Muscle can result in difficulty swallowing, a condition known as dysphagia. This can be caused by a variety of conditions, including stroke, neurological disorders, and cancer.
