Pharyngeal tonsil

Pharyngeal tonsil is a mass of lymphatic tissue located at the back of the nasal cavity in the roof of the nasopharynx where the nose blends into the throat. The pharyngeal tonsil, also known as the adenoid, plays a role in immune system activity.

Anatomy

The pharyngeal tonsil is located in the upper part of the throat behind the nasal passages. It is part of the lymphatic system, which helps to fight infections. The pharyngeal tonsil is made up of lymphoid tissue, similar to the tonsils and appendix.

Function

The primary function of the pharyngeal tonsil is to produce antibodies, or immune cells, that help to fight off infections. These antibodies are part of the body's immune system, and they help to protect the body from harmful bacteria and viruses.

Clinical significance

When the pharyngeal tonsil becomes infected or inflamed, it can cause a condition known as adenoiditis. This can lead to symptoms such as difficulty breathing through the nose, snoring, and sleep apnea. In some cases, the pharyngeal tonsil may need to be removed in a procedure known as an adenoidectomy.
