==Introduction==
The tonsils are part of the MALT and more specifically the GALT. They are located in the nasopharynx and [[Alimentary System - Horse Anatomy#Pharynx|oropharynx]] and form a ring of lymphoid tissue around the [[Alimentary System - Horse Anatomy#Pharynx|pharynx]] to protect the openings into the [[Alimentary System - Horse Anatomy|alimentary]] and [[Equine Respiratory System - Horse Anatomy#Upper Respiratory Tract|respiratory]] systems.
==Structure==
The tonsils are non-encapsulated lymphoid tissue. They have crypts lined with stratified squamous epithelium which are infiltrated with [[Lymphocytes - Introduction|lymphocytes]].
===Pharyngeal===
''Also called adenoids''
Located on the pharyngeal septum in the nasopharynx.
===Palatine===
''In common speech these are “the tonsil"''
located dorsally in the lateral walls of [[Alimentary System - Horse Anatomy#Pharynx|oropharynx]]. In horses they are diffuse.
===Soft palate===
Found on the ventral aspect of the [[Alimentary System - Horse Anatomy#Palate|soft palate]] (roof of [[Alimentary System - Horse Anatomy#Pharynx|oropharynx]]).
===Tubal===
They are located in the lateral wall of the nasopharynx and provide protection to the entrance of the auditory tubes. Compact They are diffuse in horses.
===Lingual===
Found on the floor of [[Alimentary System - Horse Anatomy#Pharynx|oropharynx]].
==Functions==
The tonsils are a [[:Category:Secondary Lymphoid Tissue|secondary lymphoid tissue]] and [[Lymphocytes#B cells|B cells]] in the tonsils become committed to synthesise [[Immunoglobulin A|IgA]].
