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.
Do Epithelial cells have ribosomes?
Yes, epithelial cells have ribosomes. Ribosomes are essential organelles responsible for protein synthesis in all types of cells, including epithelial cells, which line the surfaces of organs and body cavities. These ribosomes synthesize proteins that help maintain the structure and function of the epithelial cells.
The tissue that lines all internal surfaces is?
The tissue that lines all internal surfaces is called epithelial tissue. Epithelial tissue is made up of tightly packed cells that cover and protect organs, and it also plays a role in absorption, secretion, and sensation.
All epithelial tissues are attached to underlining tissues that hold them in place what is this membrane called?
The membrane that underlies and supports epithelial tissues is called the basement membrane. It is composed of a thin layer of extracellular matrix, which provides structural support and anchorage for the epithelial cells. The basement membrane also plays a crucial role in filtration, cell signaling, and tissue regeneration.
What is the upper free surface of all epithelial cells?
The upper free surface of all epithelial cells is known as the apical surface. This surface is exposed to the body exterior or to an internal cavity or lumen, playing a critical role in functions such as absorption, secretion, and sensation. The apical surface can have specialized structures, such as microvilli or cilia, that enhance its functional capabilities. In contrast, the opposite side of the epithelial layer, which is anchored to the underlying tissue, is called the basal surface.
The basic shapes of epithelial cells include all but?
The basic shapes of epithelial cells include squamous, cuboidal, and columnar. However, spindle shape is not a basic shape of epithelial cells.

Are epithelial cells of the trachea similar in size and structure to those lining the?
Yes, epithelial cells of the trachea are similar in size and structure to those lining the bronchi and bronchioles. They are all types of respiratory epithelial cells that are specialized for gas exchange and share similar characteristics such as ciliated cells and goblet cells.

All epithelial membranes have a layer of underneath them?
All epithelial membranes have a layer of connective tissue underneath them. This layer provides support, nourishment, and protection to the epithelial cells. It also helps anchor the epithelium to the underlying structures.

The upper free surface of all epithelial cells is known as the apical surface. This surface is exposed to the body exterior or to an internal cavity or lumen, playing a critical role in functions such as absorption, secretion, and sensation.

Where do ovarian cancers develop?
Ninety percent of all ovarian cancers develop in the cells lining the surface, or epithelium, of the ovaries and so are called epithelial cell tumors.
How do human epithelial cells and elodea cells different?
First of all elodea cells are plant cells while epithelial cells are animal. Which means elodea has: a cell wall, chloroplasts, and are square shaped. Animal Cells: round, don't have cell walls just a membrane, and because they are heterotrophic they don't have chloroplasts.
Can epithelial tissues regenerate?
Yes, epithelial tissues have the ability to regenerate due to their high rate of cell turnover. This process allows for damaged or lost epithelial cells to be replaced to maintain the integrity and function of the tissue.
Which kind of cells forms kidney tubules?
All surfaces of the body are composed of epithelial tissue.
