Tissues Flashcards
It is a group of cells that are similar in structure and function
Tissues
What are the Primary Tissue Types
E,C,M,N
Epithelium/Epithelial
Connective
Muscle
Nervous
One of the primary tissues where it is more on covering. It is the lining, covering, and glandular tissue of the body
Epithelial Tissue
Epithelial are classified according to the number of cell layers and the shape of the cells. By cell arrangement it consists of a single layer of cells
Simple Epithelium
Another classification of Epithelium by cell arrangement where it consist more than one cell layer
Stratified Epithelium
Categories of epithelium based on cell shape where it relates to scale, flattened like fish scales
Squamous
Another categories of epithelium by shape is a cube-shaped like dice; cubelike
Cuboidal
Squamous can be seen in
Blood Vessels
Cuboidal can be found in
Thyroid, Kidney, Salivary Gland
Columnar can be found in
Respiratory Tract and Reproductive System
Categories of epithelium by cell shape where it’s like columns (tall and thin)
Columnar
It is a single layer of thin squamous cells resisting on a basement membrane. Usually forms membranes where filtration or exchange of substances by raid diffusion occurs. It is in the air sacs of the lungs, where epithelium also forms the serosa
Simple Squamous Epithelium
Are most concerned with absorption, secretion, and filtration
Simple Epithelial
It is a single layer of cubelike cells. One layer of cuboidal cells resisting on a basement membrane, is common in glands and their ducts
Simple Cuboidal Epithelium
It is made up of a single layer of tall cells that fit closely together
Simple Columnar Epithelium
What cells produce a lubricating mucus often seen in this type of epithelium. Lines the entire length of the digestive tract from the stomach to anus
Goblet cells
What membrane line body cavities open to the body exterior
Mucous Membrane
Smallest blood vessels
Capillaries
It is a special type of Simple Epithelium. It rest on a basement membrane and mainly functions in absorption and secretion
Pseudostratified Columnar Epithelium
A ciliated variety more precisely called
Pseudostratified ciliated columnar epithelium
It consist of two or more cell layers and more durable so they function primarily to protect
Stratified Epithelia
It is the most common epithelium, usually consist of several layers of cells. Where it can be found in sites that receives a good deal of abuse or friction such as esophagus, the mouth and the outer portion of the skin
Stratified Squamous Epithelium
They are both rare epithelium in the body, being found mainly in the ducts of large glands
Stratified Cuboidal and Stratified Columnar Epithelia
It is a highly modified, stratified squamous epithelium that forms the lining of only a few organs, urinary bladder, ureters and part of the urethra (needs considerable stretching)
Transitional Epithelium
