Which tonsil is also known as the adenoid?

Palatine tonsil
Lingual tonsil
Pharyngeal tonsil
Cervical tonsil

The correct answer is: Pharyngeal tonsil

The pharyngeal tonsil is commonly referred to as the adenoid. This structure is located in the nasopharynx, the upper part of the throat behind the nose. The adenoid plays an important role in the immune system, particularly in the function of trapping pathogens and preventing infections, especially in children. Unlike the palatine and lingual tonsils, which are situated in the oral cavity and near the base of the tongue respectively, the pharyngeal tonsil is positioned higher in the airway. When the adenoid is enlarged, it can lead to breathing difficulties and other complications, particularly in young children, making its role significant in both health and anatomy. The cervical tonsil, while related to lymphatic tissue, is not commonly referred to in the same context as the pharyngeal tonsil or adenoid.
