Body
was changed:
The lingual tonsils are aggregations of lymphoid follicles that mediate B- and T-cell lymphocytes, which serve a role in formulating the immune system. They are covered by stratified squamous nonkeratinized epithelium and contain deep crypts and mucosal glands. They form a part of the Waldeyer ring of mucosa-associated lymphoid tissue (MALT) of the oropharynx. Diseases arising here (e.g. tumours) are classified as oropharyngeal lesions for staging, rather than oral cavity for the anterior tongue.
Location
posterior third of the dorsum of the tongue
Blood supply
lingual artery: a branch of the external carotid artery
tonsillar branch of the facial artery
ascending pharyngeal branch of the external carotid artery
Innervation
tonsillar branch of the glossopharyngeal nerve (CN IX)
