Pharyngeal tubercle

Pharyngeal Tubercle is a small bony prominence located on the lower surface of the basilar part of the occipital bone. It serves as an attachment point for the superior pharyngeal constrictor muscle, which plays a crucial role in the process of swallowing.

Etymology

The term "Pharyngeal Tubercle" is derived from the Greek word "pharynx" which means throat, and the Latin word "tuberculum" which means small swelling.

Anatomy

The Pharyngeal Tubercle is located on the lower surface of the basilar part of the occipital bone, near the foramen magnum. It is a small bony prominence that serves as an attachment point for the superior pharyngeal constrictor muscle. This muscle is one of the three pharyngeal constrictor muscles that play a crucial role in the process of swallowing by constricting the pharynx to push food down into the esophagus.

Clinical Significance

Due to its location and function, the Pharyngeal Tubercle can be involved in various medical conditions. For instance, inflammation or infection of the superior pharyngeal constrictor muscle can lead to difficulty in swallowing, a condition known as dysphagia. Furthermore, trauma or injury to the occipital bone can potentially damage the Pharyngeal Tubercle, affecting the attachment and function of the superior pharyngeal constrictor muscle.
