Histology Study Guide Review
Tissue
A group of similar cells that work together to perform a function
In terms of blood supply what is so unique about epithelium?
No blood supply in epithelium. Needs to be by a capillary to receive nutrients.
How is stratified squamous epithelium of your skin different than that lining your orifices?
Presence of Keratin makes it rough to touch
What do the terms simple and stratified mean in terms of epithelium
Simple- is one cell layer thick Stratified-is more than one cell layer thick
List the functions of neuron and neurological cells.
to bend support and supply nutrients to neurons. Store electric impulses
Of all the four basic tissue which one has the ability to reproduce the fastest?
Epithelium
Where in the body is simple squamous epithelium found
In the lung and pericardia sac. Endothelium blood vessel
What do the terms involuntary, striated, nonstraited, and voluntary mean in terms of muscle
Involuntary- no control Striated- stripped non striated- not stripped voluntary- control
What is extracellular matrix in connective tissue
cellular product but not cell
List two primary fibers found in connective tissue
collagen elastic
What are the functions of adipose tissue?
connective tissue that insulates, cushions and is a energy supply
List 3 types of cells found in blood and their functions
erythrocytes- blood is carried to oxygen glucocytes- immunity thrombocytes blood clot
List 3 types of cells found in connective tissue and their functions
fibroblast- macrophages- big cell that eats massticells- immune
Where in the body is simple cuboidal epithelium
glands, ovaries, and kidney tubules
Where is smooth muscle found in the body
hollow organs and blood vessels
Define: Cancer
is the uncontrolled growth of non functional cells
What are the functions of simple columnar epith
lines the digestive tract- protects absorbs and secrets
What is the function of cilia in epithelial tissue
moves material primary muscle
What two types of tissue display irritability?
muscle and nervous
Cells which line, protect, nourish, and support neurons are called?
nervous tissue and neuron blind
Cells of nervous tissue are called
neurons
Where is each type of cartilage found in the body
on the bones , nose- fibrous,- Hyaline Cartilage in ears, disc knee and pelvis
List 6 functions of connective tissue
protects supports fills in spaces binds repairs damaged tissue produces blood cells
Where in the body is peudostratified epithelium found
respiratory tract
Name two organs composed of nervous tissue
spinal cord brain
What is meant by the term malignant
spreads through the body
histology
study of tissue
What structures are composed of fibrous connective tissue
tendons and ligaments
What are the functions of simple squamous epithelium
absorption and secretion
what function are for loose connective tissue
binds our skin to underlying tissues, fills in spaces, and helps repair tissue damage
List six types of connective tissue and one function of each
Loose connective-binds our skin to underlying tissues, fills in spaces, and helps repair tissue damage fibrous connective-connective tissue composed entirely of collagen and makes tendons and ligaments adipose-connective tissue that insulates, cushions and is a energy supply cartilage-very rigid, supports, provides framework, and serves as attachment for muscles. Cells are called chondrocytes bone-connective tissue that provides framework that supports and protects and produces blood cells and stores minerals and is the most rigid blood-tissue with a liquid matrix and cellular components which transports gases nutrients and fights infection
List the 3 types of muscle tissue and were they are found
Skeletal- skeleton Smooth-blood vessels and hollow organs cardiac-heart
Muscle cells do one thing what is it?
They contract-shorten
What is the function of cartilage
Tissue that supports, protects, serves as attachment for muscles and produces chondrocyctes
