Tissues Flashcards
It is the microscopic study of tissue structure
Histology
A group of cells with similar structure and function
Tissues
It is the cover or lining tissue
Epithelial Tissue
It is the diverse primary tissue; makes up the part of every organ in the body
Connective Tissue
Tissue that contracts or shortens
Muscle Tissue
They are responsible for coordinating and controlling many body activities
Nervous Tissue
It covers and protects both outsides and insides of the body
Epithelial Tissue
Epithelial Tissue is also known as
Epithelium or Epithelial
These are the cells exposed and not attached to other cells
Free (Apical) surfaces
Cells are attached to other epithelial cells
Lateral Surface
It is the base of the cell; attached to the basement membrane
Basal Surface
Attaches to the epithelial cells of the underlying tissue which supports and guides the cell migration during tissue repair
Basal Membrane
It consists of a single layer of cells, with each cell extending from the basement membrane to the free surface
Simple Layer
More than one layer of cells, but only the basal layer attached the deepest later to the basement membrane
Stratified Layer
A special type of simple epithelium, that appears to be falsely stratified
Has one layer of cells, with all cells attached to the basement membrane
Pseudostratified Layer
Flat or scalelike shape
Squamous
Taller than wide in appearance
Columnar
Cube-shaped, wide rather than tall
Cuboidal
Cube-shaped, wide rather than tall
Cuboidal
Simple Squamous Epithelium definition
A single layer of thin and flat cell
Some substances easily pass through this thin layer of cells, but other substances do not
Simple Columnar Epithelium definition
The large size of these cells enables them to perform complex functions, such as secretion
Simple Cuboidal Epithelium definition
A single layer of cube-like cells that carry out active transport, facilitated diffusion, or secretion
Pseudostratified Columnar Epithelium definition
Secretes mucus which covers its free surface
Stratified Squamous Epithelium definition
Forms a thick epithelium because it consists of several layers of cells
Compromised of the keratinized squamous epithelium; Reduces loss of water from the body
Keratinized Stratified Squamous Epithelium
Moist keratinized stratified squamous epithelium; provides protection against abrasion and acts as a mechanical barrier
Non-Keratinized Stratified Squamous Epithelium
Consist of more than one layer of cuboidal epithelial cells; Relatively rare and is found in sweat gland ducts, ovarian follicular cells, and the salivary glands [absorption, secretion, protection]
Stratified Cuboidal Epithelium
Consist of more than one layer of epithelial cells; the surface cells are columnar but deeper cells are irregular or cuboidal shape
Stratified Columnar Epithelium
Special Type of stratified epithelium that can be greatly stretched
Transitional epithelium
Have several structures that hold one cell to one another or to the basement membrane
