Explanation:
Difference Between Ciliated Epithelial Cell and Squamous Epithelial Cell
Definition
Ciliated Epithelial Cell: Ciliated epithelial cell refers to an epithelium that bears vibratile, hairlike processes called cilia on the free surface of the epithelium.
Squamous Epithelial Cell: Squamous epithelial cell refers to an epithelium that consists of one or more cell layers of flat, scale-like or plate-like cells.
Specializations
Ciliated Epithelial Cell: Ciliated epithelial cell consists of cilia.
Squamous Epithelial Cell: Squamous epithelial cell lacks cilia.
Type of Epithelia
Ciliated Epithelial Cell: Ciliated epithelial cell can form either simple columnar epithelium or pseudostratified columnar epithelium.
Squamous Epithelial Cell: Squamous epithelial cell can form either simple squamous epithelium or stratified squamous epithelium.
Nucleus
Ciliated Epithelial Cell: The nucleus of the simple columnar epithelial cell is located at the bottom part of the cell. The nucleus of the pseudostratified columnar epithelial cell is located in different heights.
Squamous Epithelial Cell: The nucleus of the squamous epithelial cell is centrally-located.
Significance
Ciliated Epithelial Cell: Ciliated epithelial cells are mainly found on the inner surfaces of the body.
Squamous Epithelial Cell: Squamous epithelial cells are mainly found in the passages that open to the external environment.
Location
Ciliated Epithelial Cell: Simple columnar epithelium can be found in the lining of bronchi, uterine tubes, and uterus. Pseudostratified columnar epithelium can be found in the trachea and upper respiratory tract.
Squamous Epithelial Cell: Simple squamous epithelium can be found in the lining of airways, heart, blood vessels, and lymphatic vessels. Stratified squamous epithelium can be found in mouth, esophagus, and vagina.
Function
Ciliated Epithelial Cell: The main function of the ciliated epithelial cell is to secrete mucus and beat rhythmically to move mucus through a duct along with pathogens and other particles.
Squamous Epithelial Cell: The main function of the simple squamous epithelial cell is to move particles through diffusion or filtration and to secrete mucus. Stratified squamous epithelium protects the body against abrasion.
Conclusion
Ciliated epithelial cell and squamous epithelial cell are two types of epithelial cell that line the body. The ciliated epithelial cell consists of cilia that allow the movement of mucus through a duct along with foreign particles. Squamous epithelial cell lacks cilia, and it is mainly involved in the secretion and absorption. Therefore, the main difference between ciliated epithelial cell and squamous epithelial cell is the presence of cilia and function of each epithelial cell in the body.
