Difference between Elastic Cartilage and Elastic Connective Tissue

Elastic Cartilage

Cartilage is a flexible connective tissue of three major types: hyaline cartilage, fibrocartilage and elastic cartilage. Elastic cartilage, also called yellow cartilage, are supporting tissues in an animal’s body. They provide strength and elasticity to the structures they are present in. They are mostly made of elastin fibres which give the yellow colour. The cells of the elastic cartilage are called chondrocytes, which are present inside spaces called lacunae. It contains chondroitin sulfate in its extracellular matrix, which forms proteoglycans and gives it a peculiar appearance from all other connective tissues.

Elastic Connective Tissue

Elastic connective tissue is a type of dense connective tissue. They provide tensile strength and resistance to stretching. They contain both elastin and collagen fibres called fibroblasts. The elastin fibers give it a property of elasticity so that a structure can return to its original position even after stretching.

Definition

Elastic cartilages are types of cartilage which provide rigidity and strength to the structures they are present in.

Elastic connective tissues are dense connective tissues which provide tensile strength and elasticity to the structures they are present in.

Types of cells

They have elastin fibres called chondrocytes.

They have elastin fibres in addition to collagen fibres called fibroblasts.

Location

They are present in the ear, epiglottis and larynx.

Lungs and arteries, dermis layer, ligaments and tendons.

Presence of chondroitin sulfate

Chondroitin sulfate is present.

Chondroitin sulfate is absent.

Strongness

They are much stronger.

Less strong in comparison.

Type of fibers

It contains type II collagen fibres.

It contains type I collagen fibres.

Frequently Asked Questions

Is elastic cartilage and elastic connective tissue the same?

No, elastic cartilage is a type of connective tissue which contains chondroitin sulfate, whereas elastic connective tissue is a type of dense connective tissue, which does not contain chondroitin sulfate.

What is the difference between elastic cartilage and hyaline cartilage?

Elastic cartilage is the least common type of connective tissue, yellow in color, whereas hyaline cartilage is the most common type and has a glassy appearance.

Give an example of elastic cartilage.

Ear lobes. Try tugging your ear lobe gently, it will come back to its initial position.

What is in the elastic cartilage?

The elastic cartilage contains elastin fibres which give it a yellowish appearance.
