What two factors determine the distance from the free surface to the basal surface in epithelial tissue?
The presence of different types of cells and their positioning within the epithelial layer determine the distance from the free surface to the basal surface in epithelial tissue. Additionally, the function of the epithelial tissue in a specific organ or structure can influence the thickness of the tissue layer.
What tissue is microvilli and goblet cells associated with?
Microvilli are associated with the epithelial tissue lining the small intestine, where they increase surface area for absorption. Goblet cells are specialized cells found in the epithelial tissue of the respiratory and digestive tracts, where they secrete mucus to protect and lubricate the lining of these organs.
Is a stratified squamous epithelial tissue?
Stratified squamous epithelial tissue is composed of multiple layers of squamous (flattened) cells that provide protection against mechanical stress and damage. It is found in areas of the body that are subject to abrasion and friction, such as the skin, oral cavity, and esophagus. This tissue type allows for regeneration of cells to maintain its protective function.
The inner surface of epithelial tissue rests on a?
The inner surface of epithelial tissue rests on a basement membrane, which is a thin layer of extracellular matrix secreted by the epithelial cells themselves. This basement membrane provides structural support and helps anchor the epithelial tissue to underlying connective tissue.
The tissue that always has a ʺtopʺ and a ʺbottomʺ is?
Epithelial tissue always has a "top" (apical surface facing the outside or a body cavity) and a "bottom" (basal surface attached to underlying connective tissue). This arrangement allows epithelial cells to perform functions such as protection, secretion, and absorption efficiently.
A primary oocyte is closely surrounded by flattened epithelial cells called?
Primary oocyte is surrounded by flattened epithelial cells called follicular cells.

What cells has one free surface and lack blood vessels?
epithelial tissue

Flattened cells important in protection?
Flattened cells, such as squamous epithelial cells, are important in protection because their flat shape helps create a barrier that prevents the entry of pathogens and other harmful substances. They can form tight junctions that reduce the permeability of tissues, aiding in protection against infection and injury. Additionally, their large surface area allows for efficient exchange of gases and nutrients, crucial for maintaining tissue health.

In adults new surface epithelial cells and the epithelial cells lining the intestine are derived from?
In adults, new surface epithelial cells and the epithelial cells lining the intestine are derived from stem cells located in the basal region of the epithelium. These stem cells continuously divide and differentiate to replace damaged or lost cells, maintaining the integrity and function of the tissue.
Name the flattened cells important in protection that fit together like tiles?
Squamous epithelial cells are the flattened cells important in protection that fit together like tiles. These cells create a tight barrier that helps protect underlying tissues from damage and provide a smooth surface for processes like gas exchange.
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.
Tissue that covers organs?
The tissue that covers organs is called epithelial tissue. These cells form a protective barrier against infections, regulate the passage of molecules, and provide a smooth surface for organs to function properly. Epithelial tissue can be found lining internal cavities and organs throughout the body.
