What is palatine tonsil in anatomy?
The palatine (or faucial) tonsils, commonly referred to as tonsils, are bundles of lymphatic tissue located in the lateral oropharynx. They sit in the isthmus of the fauces, bordered anteriorly by the palatoglossal arch and posteriorly by the palatopharyngeal arch.
What are the 5 tonsils?
The tonsils are a set of lymphoid organs facing into the aerodigestive tract, which is known as Waldeyer’s tonsillar ring and consists of the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsils. These organs play an important role in the immune system.
What are the 3 types of tonsils?

- Pharyngeal tonsils (adenoids), which reside behind your nose.
- Two palatine tonsils (what people are most commonly referring to when they say the word ‘tonsils’), which reside on both sides of the back of the throat.

What is the function of the Fauces?
Each arch runs downwards, laterally and forwards, from the soft palate to the side of the tongue. The approximation of the arches due to the contraction of the palatoglossal muscles constricts the fauces, and is essential to swallowing….Fauces (throat)
What tissue type are the palatine tonsils?
The palatine tonsils, in addition to the adenoids and lingual tonsils, are classified as mucosa-associated lymphoid tissue. They are housed in the tonsillar fossa, bordered by the palatoglossus anteriorly, palatopharyngeus posteriorly, superior constrictor laterally, and the base of the tongue inferiorly.
Where are the Palatine and lingual tonsils located?
The palatine tonsils are the ones that are located near the opening of the oral cavity into the pharynx. Lingual tonsils are located on the posterior surface of the tongue, which also places them near the opening of the oral cavity into the pharynx.

What is the purpose of the palatine tonsil?
The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites. In consequence it is a site of, and potential focus for, infections,…
What is the function of palatine tonsils?
Palatine tonsil function is an important part of our immune system. As described by the Institute for Quality and Efficiency in Health Care , the tonsils use their supply of white blood cells to help fight viruses and bacteria in the body.

What is the structure and location of tonsils?
Structure of Tonsils. The tonsils (also known as palatine tonsils) are a pair of lymphoid tissue mass located in the tonsillar fossa which is present on the lateral wall of the oropharynx. The tonsillar mass extends upwards to the soft palate and downwards to the dorsum (lower surface) of the tongue.
