Types of Tissues Flashcards
What are the four types of tissues?
Epithelial, connective, muscle, and nervous.
What is the difference between plasma and interstitial fluid?
Plasma is the liquid portion of the blood, interstitial fluid fills the space between cells in tissues.
What is the difference between a desmosome and a hemidesmosome.
A hemidesmosome will only have a plaque on one side while a desmosome has plaques on both of the tissues that it is connecting.
Which three types of junction involve anchoring?
Adherens, desmosome, and hemidesmosome.
In which type of junction can an adhesion belt be found?
An adherens junction.
Why is a gap junction useful?
It allows for cell to cell communication.
What is the SNAIL gene and what does it do?
When it is activated, it leads to the suppression of cadherin production which causes epithelial cells to not stack up properly, called dysplasia of the cells, which results in carcinoma.
Where in the body can simple cuboidal epithelium be found?
The intralobular duct of the pancreas.
What kinds of cells produce mucous?
Goblet cells.
What is the difference between cilia and microvilli?
Cilia are motile and facilitate movement of substances over the cell’s surface, while microvilli are non-motile and increase absorption by increasing the surface area of the tissue.
Where in the body can simple columnar epithelium be found?
The fallopian tubes.
Where can pseudostratified columnar epithelium be found?
In the trachea
Where can stratified squamous epithelium be found?
Skin and in the vagina
Where can stratified cuboidal epithelium be found?
In the esophagus
Where can transitional epithelium be found?
In the urinary bladder.
