Epithelial cells are generally divided into two main groups:
Simple and Stratified
Simple epithelium is of a single cell thickness and every cell is in contiguous contact with the basal lamina by hemi desmosomes (cell anchors). These can be further subdivided into other groups.
Stratified epithelium is multilayered arranged into 'strata' and is found in the body where the cells in contact with the lumen are lost frequently due to mechanical or chemical stressers (e.g small intestine or skin cells). The cells are held together by intermediate filaments and desmosomes. These can be further subdivised into other groups.
The features of the groups vary widely depending on the sub-specialisation e.g. stratified squamous keratinised epithelium makes up skin cells and has very different features to simple cuboidal epithelium such as that found in the testicle.
What else can I help you with?
Which of the following would be produced by meiosis red blood cell cells of the stem in plants sperm cell or epithelial cell?
Meiosis would produce sperm cells and epithelial cells in plants. Red blood cells do not undergo meiosis, as they lack a nucleus and are not capable of dividing.
If you examine a population of intestinal epithelial cells under a microscope most of the cells would appear in what phase of the cell cycle?
Most of the intestinal epithelial cells would likely be in the G1 phase of the cell cycle, as they are constantly renewing and dividing to maintain the integrity of the intestinal lining.
Epithelial cells are classified as?
Epithelial cells are classified based on their shape (squamous, cuboidal, columnar) and the number of cell layers (simple or stratified). They can also be categorized based on their function, such as ciliated columnar epithelium found in the respiratory tract for moving mucus.
Epithelial cells are specialized for all the following functions?
Without knowing what the functions are a person will have difficulty knowing which are specialized for epithelial cells. Including the functions would insure that a person will provide the correct answer.
What type of tissue would look like large cells spaced closely together with a large nucleus?
The type of tissue that fits this description is epithelial tissue. Epithelial cells are tightly packed together with large nuclei located near the basal surface. This arrangement allows epithelial tissue to form protective barriers in the body and facilitate the exchange of substances.
What would a group of ciliated epithelial cells be called?
ciliated epithelial tissue
Non-squamous cells - likely transitional epithelial cells - is it cancer?
Non-squamous cells, including transitional epithelial cells, are not necessarily indicative of cancer. Transitional epithelial cells are typically found in the urinary tract and can appear in urine samples without suggesting malignancy. However, if there is an unusual number or atypical features in these cells, further investigation may be warranted to rule out cancer or other conditions. A definitive diagnosis would require additional testing, such as a biopsy or imaging studies.
Why the presence of epithelial cells in urine are reason for pelvic cavity pain?
Epithelial cells in urine would be a pretty good indicator of an infection, this the pelvic pain. ( Maybe kidney or Bladder)
What is tissue that is composed of closely packed cells with little extracellular material?
Epithelial tissue are closely connected and have a basal membrane, even though not all epithelial cells are necessarily connected to the basal membrane. The so called simple epithelial tissue subgroup does.
Which of the following would be produced by meiosis red blood cell cells of the stem in plants sperm cell or epithelial cell?
Meiosis would produce sperm cells and epithelial cells in plants. Red blood cells do not undergo meiosis, as they lack a nucleus and are not capable of dividing.
If you were looking at specialized cells from a tissue how would you know if they came from a sample of epithelial?
Cells would fit closely together to form a barrier
If we were to compare the muscle cells of the puma to the epithelial cells would the muscle cells contain relatively more?
If we compare the muscle cells of a puma to epithelial cells, the muscle cells would contain relatively more myofibrils, which are essential for contraction and movement. Additionally, muscle cells typically have a higher number of mitochondria to meet their energy demands during physical activity. In contrast, epithelial cells are more focused on functions such as protection, absorption, and secretion, and therefore have fewer myofibrils and mitochondria.

What side of an epithelial cell is closest to the blood vessel?
I think that the bottom of epithelial cells is closest to blood vessels (if one were to look at a flat 2D image. Endothelial cells similarly would have the top of the cell closest to blood vessels.
