What type of tissue has an apical and basal surface?
Epithelial tissue lines body surfaces and cavities as have apical and basement sides.
Do epithelial tissues always exhibit polarity?
Yes, all epithelial exhibit what is called apical-basal polarity
What types of cell junctions connect cells within tissues?
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
Binds epithelial tissue to underlining tissues?
Basal membrane.
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.
What type of tissue has an apical and basal surface?

Do epithelial tissues always exhibit polarity?
Yes, all epithelial exhibit what is called apical-basal polarity
An epithelial cell can be divided into two functional regions They are the surface and the surface?
An epithelial cell can be divided into basal and apical functional regions.
How do avascular tissue receive nutreints?
By diffusion or absorption across the apical or basal surfaces of Epithelium.
What are ten different cell parts in a human epithelial cell?
The cell parts of an epithelial cell include; apical and basal regions and a basement membrane (basal lamina). Epithelial cells are held together by desmosomes, adherens, tight junctions and gap junctions.
What types of cell junctions connect cells within tissues?
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
What multilayered epithelium with cuboidal basal cells and flat cells at its surface would be classified as?
Multiple cell layers whose apical cells are flattened are stratified squamous. These are epithelial cells arranged in layers upon a basal membrane.
Does All epithelia have an apical surface and a basal surface?
YES
Binds epithelial tissue to underlining tissues?
Basal membrane.
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.
What layers do hair nails and epithelial tissue develope?
From basal layer. This layer is called as stratum basale.
What two factors determine the distance from the free surface to the basal surface in epithelial tissue?
Speed and distance
