What is the common name for the masses of lymphatic tissue found in the pharynx?
adenoids, also called Pharyngeal Tonsils, a mass of lymphatic tissue, similar to the (palatine) tonsils, that is attached to the back wall of the nasal pharynx (i.e., the upper part of the throat opening into the nasal cavity proper).
What tissues make up the oral mucosa?
The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed “oral epithelium”, and an underlying connective tissue termed lamina propria.

What type of epithelium is found lining the inside of the mouth and esophagus?
Simple squamous epithelial cells are extremely thin and flat and form a delicate lining. The oesophagus and the lining of the mouth, alveoli of the lungs, etc are lined with squamous epithelium.
What is the enlarged mass of lymphoid tissue in the upper pharynx?
tonsil, small mass of lymphatic tissue located in the wall of the pharynx at the rear of the throat of humans and other mammals. In humans, the term is used to designate any of three sets of tonsils, most commonly the palatine tonsils.

What is the tissue inside your mouth called?
The oral mucosa are the tissues that line the interior of your mouth, while the salivary glands produce saliva. The bottom of your mouth, located under your tongue, is called the floor.
What is Peyer’s patch?
Peyer’s patches are a group of well-organized lymphoid follicles located in the lamina propria and submucosa of the distal portion of the small intestine – the ileum and jejunum and sometimes in the duodenum. Almost 50% of these patches are in the distal ileum.
Where are Peyer’s patches located and what is their function?
Peyer’s patches are located in your small intestine, usually in the ileum area. The ileum is the last portion of your small intestine. In addition to further digesting the food you eat, the ileum also absorbs water and nutrients from food.

squamous epithelium
The oesophagus and the lining of the mouth are lined with squamous epithelium.
What type of epithelial tissue is found in the mouth?
stratified squamous epithelium
All of the oral mucosa is made up of a thick stratified squamous epithelium, supported by a lamina propria. The epithelium is thick because the epithelial lining of the oral cavity is subject to a lot of wear and tear.
What type of tissue is found in the lining of the mouth What is its function?
Stratified squamous epithelium forms the inner lining of the mouth. This tissue gives protection against mechanical injury and also blocks the entry of germs.
What is lymphoid tissue in the throat?
Tonsils. The tonsils are lymphoid tissues that are found at the back of the throat and help fight infection. The tonsils that we all know about are the ones on the sides of the throat and can be seen when you look at your throat in the mirror and these are called palatine tonsils.
What lies between the epithelium and connective tissue in the oral mucosa?
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa.
Which epithelial cell is present in the superficial layer of the oral mucosa quizlet?
Nonkeratinized stratified squamous epithelium is the superficial layer of the: lining mucosa. Lining mucosa has three layers: basal layer, intermediate layer, and superficial layer.
Which type of oral mucosa covers the inside of the cheeks?
The inner lining of the cheeks.
