Epithelial Tissue Flashcards
(25 cards)
The four types of tissue
epithelial, connective, muscle, and nervous
Is epithelial vascular or avascular?
avascular (but has nerve endings)
the four types of epithelial tissue
squamous, cuboidal, columnar, and transitional
Difference between simple and stratified
simple = single layer stratified = several layers
Single layer of cube-shaped cells with centrally located nuclei
simple cuboidal
locations of simple cuboidal in the body
kidney tubules and the covering of the ovary
the two gland types
Endocrine- these glands make their product and secrete into the matrix.
Exocrine- these glands secrete their product outside of themselves using a duct.
Locations of stratified squamous in the body
outer layer of skin. Also lines the mouth, throat, vagina, and anal canal.
This tissue is well suited for diffusion
simple squamous
Locations of simple squamous in the body
inside of all blood vessels (endothelium)
inside of the heart (endocardium)
the walls of capillaries
This tissue’s nuclei are found at the base of the cell
simple columnar
Locations of simple columnar in the body
GI tract
female reproductive system
This tissue is found in one’s mammary glands, sweat glands, salivary glands, and pancreas (the body’s larger glands).
stratified cuboidal
This tissue is found in vas deferens (male reproductive) and lines the respiratory tract.
pseudostratified columnar
This tissue says it is stratified, but it isn’t
pseudostratified columnar
Location of transitional epithelium in the body
Lines the urinary bladder
The three main types of epithelial membranes
cutaneous, mucous, and serous
What do melanocytes release?
melanin
The tough, protective, and waterproof protein that is the key structural material that makes up the outer layer of skin
keratin
Any type of cancer to the epithelial tissue (skin cancer).
carcinoma
Out of basel cell carcinoma, squamous cell carcinoma, and malignant melanoma, which carcinoma is deadly?
malignant melanoma
ABCD method for moles
A = asymmetry B = boarder C = color D = diameter
What is the “rule of nines”?
A procedure that assesses the percentage of burn and is used to help guide treatment decisions.
Most common carcinoma
basal cell carcinoma
