Areolar Tissue

What tissue is this?

Reticular Tissue

What is this tissue?

Hyaline Cartilage

This type of connective tissue forms strong rope like structures such as tendons and ligaments, where collagen fibers all go in the same direction. This allows them to stretch in that direction ONLY, which is important to prevent dislocations.

Dense regular tissue

What tissue is this?

Adipose

This tissue carries nutrients, waste, respiratory gases, and many other substances throughout the body.

Blood

Which connective tissue contains a gel-like matrix and is found in the nose, ear, and at the ends of the bones

Cartilage

What type of fiber is long and thin and allows for stretch and recoil?

Elastin

Which type of tissue is the most widely distributed, supports and binds other tissues, the universal packing material?

Areolar

This type of fibers is extremely tough and provides strength to the connective tissues.

Collagen

This fiber is stretchy and bounce back like rubber bands.

Elastic

This fiber is made of shorter, thinner, branched collagen fibers. They form nets to support your organs.

Reticular

Which type of fiber is thick and very strong?

Collagen

Serves as a packing material that wraps and cushions organs

Areolar
