An epithelial cell can be divided into two functional regions They are the surface and the surface?
An epithelial cell can be divided into two functional regions: the apical surface, which faces the external environment or a body cavity, and the basolateral surface, which interacts with neighboring cells and the extracellular matrix. These regions are important for different functions such as absorption, secretion, and cell-cell communication.
What multilayered epithelium with cuboidal basal cells and flat cells at its surface would be classified as?
This type of epithelium would be classified as stratified cuboidal epithelium. It consists of multiple layers of cells where the basal cells are cuboidal in shape, while the superficial cells are flat. Typically, this type of epithelium is found in ducts of certain glands and parts of the respiratory tract.
Does All epithelia have an apical surface and a basal surface?
Yes, epithelia have an apical surface facing the external environment or a body cavity and a basal surface attached to underlying connective tissue. These surfaces are important for cell polarity and function in processes such as absorption, secretion, and barrier formation.
What side of epithelial faces the lumen?
Apical Border is the side of an epithelial cell that faces the lumen.
What are all the epitherial tissues?
The epithelial tissues are categorized into simple epithelium (one layer of cells), stratified epithelium (multiple layers of cells), squamous epithelium (flat cells), cuboidal epithelium (cube-shaped cells), and columnar epithelium (elongated cells). Epithelial tissues can be further classified based on their specific cell shape and function, such as ciliated epithelium, glandular epithelium, or transitional epithelium.
Human epithelium contains a layer of cubed shaped cells. If the length, height, and width of such a cell is one micrometer (μm), what is the surface area of its cell membrane?
6μm2
Are there cilia at the apical surface?
Yes, cilia are present on the apical surface of some cells. They serve various functions, such as moving substances along the cell surface or sensing the environment.
What does an apical cell do and what are its functions?
An apical is ontop of an epitheilial cell
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.

Where does cell renewal of junctional epithelium take place?
Cell renewal of junctional epithelium takes place at the base of the epithelium through cell division and migration from the basal layer towards the surface. This process occurs in the gingival sulcus, the space between the tooth surface and the epithelial tissue.
Does simple epithelial always consist of a layer of flat cells?
No, simple epithelium does not always consist of a layer of flat cells. Simple epithelium can consist of various cell shapes, including squamous (flat), cuboidal (cube-shaped), and columnar (column-shaped) cells. The choice of cell shape depends on the specific function and location of the epithelium.
How does it differ structurally from other stratified squamous epithelia?
transitional epithelium is the modified form of staratified epithelium this epithelium are mostly found in the organ of urinary system and is also called urothelium. it has got especial property exapanding and contracting for example in case of urinary bladder . in transitionna epithelium surface cell are umbrella shape and is covered by glycoprotein but in case of stratified squamous epithelium surface cell is flat. has no capacity of cantractying and dilating . if it stratified squamous non keratinized than surface cell has nucleus no keratin covering if it is stratified squamous keratinized than surface cell has no nucleus and is covered by keratin this both type of stratified epithelium are mostly found in those places where body suffer with friction for example esophagous , dermis of skin . this both type of stratified epithelium has special proprty by which surface layer cell is replaced by new layer of cell due to mitosis division of basal layer cell transitional

What is an apical cell?
An apical cell is the primary cell located at the tip of a plant shoot or root. It is responsible for the growth and development of the plant by producing new cells through cell division. The apical cell is important for determining the overall shape and structure of the plant.
