Cheek cells are cells that the basal mucosa, which is the tissue that currently the within of the mouth. Their primary role is to create proteins dubbed mucins, which are the an easy component of mucus and aid to store the within of the mouth moist. This is critical for the chewing, softening, swallowing, and digestion that food. Cheek cells also contribute to inherent immunity by making up the oral epithelial barrier, which stays clear of pathogens from entering the bloodstream in the mouth.

What is a Cheek Cell?

Cheek cells (AKAbuccal epithelial cells) make up thebasal mucosa;i.e., the tissue that lines the within of the mouth. Cheek cells space constantly burned from the buccal mucosa, and divide every 24 hours to compensate because that this. Castle are easy to remove from the inside of the cheek making use of a swab, and also can be perceived under a light microscope, for this reason cheek cell are often studied in school laboratories.

Structure of Cheek Cells


A cheek cabinet is a good example that a typical pet cell, i beg your pardon is another reason for your popularity in institution laboratories. Favor all eukaryotic bio cells, cheek cells absence a cell wall. Instead, they room surrounded by a plasma membrane, which offers them a round, rarely often, rarely shape. Castle contain a influential nucleus and other membrane-bound organelles, such together mitochondria and endoplasmic reticulum.

Function of Cheek Cells

The cheek cells have actually two crucial functions. Their main job is to secrete mucins, which room a principal ingredient in rubber and assist to store the inside of the mouth moist. However, cheek cells space also component of the natural immune mechanism and kind a physical barrier versus pathogens and toxins in the mouth.

Mucin Secretion

The primary duty of cheek cell is tosecrete proteins dubbed mucins, which are a an essential component the mucus. When an unified with saliva indigenous the salient glands, mucins aid to store the interior of the mouth moist. This helps v the chewing, softening, enzymatic digestion, and swallowing the food. Therefore, cheek cell play a central role in initiating the cradle of food.

Protection versus Pathogens

Cheek cells form a physics barrier against pathogens in the mouth


Cheek cells comprise the oral epithelial obstacle inside the mouth, i beg your pardon is thebody’s an initial line the defense versus pathogensand toxins. Transmittable agents that go into the mouth v food are unable to permeate this barrier to get in the bloodstream. Instead, they space swallowed and also ultimately ruined by the strong acidic conditions of the stomach.

Cheek Cells and also DNA Testing

DNA trial and error is a laboratory an approach used to analyze a person’s DNA and may be performed for a variety of reasons. For example, a DNA test might be supplied to confirm the parentage that a child, diagnose hereditary disorders, or recognize the perpetrator of a crime.Cheek cells are often used together a source of DNA, as they space easily acquired without any type of need for invasive procedures. They space constantly melted from the basal mucosa and also can it is in painlessly removed by rubbing a cotton swab versus the within of the cheek.

Once a sample that cheek cells has actually been obtained, DNA is extract from your nuclei and magnified using apolymerase chain reaction(PCR). The PCR creates millions or also billions of duplicates of the DNA molecule in the sample. This significantly increases the amount of DNA, which makes it possible to analysis using other laboratory techniques.
