C. neurons

All of the following are examples of connective tissue except: a. bones b. ligaments c. neurons d. tendons

Firbrocartilage

Description: matrix similar to but less firm than matrix in hyaline cartilage; thick collagen fibers predominate Function: tensile strength with the ability to absorb shock Location: intervertebral disks & discs of knee joint

dense irregular connective tissue

Description: primarily irregularly arranged collagen fibers; some elastic fibers; major cell type is the fibroblast Function: able to withstand tension exerted in many directions; provides structural strength Location: dermis of the skin & submucosa of digestive tract

lining hollow organs

transitional epithelium Function: stretches readily & permits distension of urinary organ by contained urine Location: lines urinary bladder

Name the tissue: Name a function of the tissue: Name a location where this tissue is found:

one type of epithelial cell, arranged in a single layer

Simple epithelia have ________.

are thin and flat, like fish scales

Squamous epithelial cells ________.

dense regular connective tissue

This connective tissue looks like strands of wavy hair. It is very strong and attaches muscles to bones.

simple cuboidal epithelium

This epithelial tissue forms the kidney tubules, and the ducts and secretory portions of small glands.

stratified squamous epithelium

This epithelial tissue has many cell layers. It forms the outer layer of the skin.

Fibrocartilage

This is the toughest kind of cartilage. It is found in places that receive a lot of mechanical stress.

simple squamous epithelium

This tissue can look like the hexagonal tiles of a bathroom floor. It also forms the air sacs of the lungs.

dense irregular connective tissue

This tough, strong, connective tissue is found beneath the epithelial tissue of the skin. It is packed with collagen fibers that run in all different directions.

areolar connective tissue

This type of connective tissue is found under epithelia, packaging organs, and surrounding capillaries.

epithelial tissue

This type of tissue is avascular, which means it has no direct blood flow

connective tissue

This type of tissue is vascular except for cartilage & ligaments and tendons are poorly vasculated

Fibroblasts

Which of the cell types is primarily responsible for producing protein fibers found in connective tissue proper?
