GENERAL HISTOLOGY

Detailed explanation-1: -The pharyngeal tonsils are located near the opening of the nasal cavity into the pharynx. When these tonsils become enlarged they may interfere with breathing and are called adenoids. The palatine tonsils are the ones that are located near the opening of the oral cavity into the pharynx.

Detailed explanation-2: -Lymphoid tissue known as the adenoids or the pharyngeal tonsils occupies the posterosuperior surface of the nasopharynx and is part of a larger collection of lymphoid tissue known as Waldeyer’s ring.

Detailed explanation-3: -The two palatine tonsils are found on the right and left of the back of the throat, and are the only tonsils that can be seen unaided when you open your mouth. The adenoids are found high up in the throat, behind the nose, and can only be seen through rhinoscopy (an examination of the inside of the nose).

Detailed explanation-4: -The pharyngeal tonsil (adenoid; nasopharyngeal tonsil) is a mass of lymphatic tissue situated posterior to the nasal cavity, in the roof of the nasopharynx.
