What type of epithelium is on palatine tonsil?

What type of epithelium is on palatine tonsil?

parakeratinised squamous epithelium
The palatine tonsil is covered by 15-20 layers of either flattened non-keratinised- or parakeratinised squamous epithelium resting on a basement membrane. A layer of fibrous connective tissue separates the surface epithelium from the lymphoid component.

What cells are present in tonsils?

2.7(a)), IgM+ B cells, some IgY+ B cells and occasionally IgM+ and IgA+ plasma cells, and few CD4+ cells and CD8+ T cells expressing the γδ- or αβ-TCR (Fig. 2.7(b), (c), (e) and (f)). Mononuclear phagocytes can be found throughout the tonsils, but are most prevalent directly under the epithelium (Fig.

Which tonsil has Pseudostratified epithelium?

Which of the following is a pharyngeal tonsil?

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). An individual fold of such nasopharyngeal lymphatic tissue is called an adenoid.

What are pharyngeal tonsils?

The pharyngeal tonsils are located near the opening of the nasal cavity into the pharynx. When these tonsils become enlarged they may interfere with breathing and are called adenoids. The palatine tonsils are the ones that are located near the opening of the oral cavity into the pharynx.
