BUCCAL CAVITY -

Situated between upper & lower jaw. It is lined by stratified squamous epithelium.
Separated from nasal chamber by palate. Palate forms roof of buccal cavity.
Palate is modification of premexilla, maxilla and palatine bones.
Anterior palate is hard palate due to palatine ridges or rugae.
Posterior palate is soft palate without rugae, in the end it forms UVULA or Velum peleti.
Uvula is made up of connetive tissue & muscles.
Close to velum peleti in pharyangeal wall 6 tonsils present.
Tonsils are made up of lymphoid tissue, commonly known as guard of body.
Tonsils are arranged in the form of a ring. The ring of tonsils is called Waldeyer's ring.
