Question

How does Hyaline cartilage differ from elastic cartilage?

Answer 1

The cartilage is an elastic tissue which is seen covering the long bones, joints, nerves. It is a smooth resilient tissue which can be seen in the ear, nose, bronchial tubes and many other components of the body. The cartilage in the body is flexible which helps in the motion of the fluids in the strong or long bones.

Complete answer:

Hyaline Cartilage	Elastic Cartilage
It contains collagen fibres	It contains elastic fibres
It appears in translucent white colour	It appears in yellow colour
It is strong resilient, stiff	It is more flexible because it contains elastic fibres
They can be found in the upper respiratory tract, surface of bones, epiphyseal plate of bones.	They can be found in the pinna of ear, auditory canal, Eustachian tubes, epiglottis etc.,
Perichondrium is observed except in few joint	Perichondrium is observed in this cartilage.
They contain type ll with abundance	They contain type II collagen in the matrix but abundance of elastic.
They contain the chondrocyte per lacuna which are closely packed	They contain a large amount of chondrocytes within them.
They are completely distributed in the body but found to restricted to the bones which are smooth as it is translucent	They are distributed all over the body organs with joints, and bones because the elastic tissue is more flexible and stable.

Note: The cartilage is stiff but compared to muscular tissue it is less flexible. The major function of the both elastic and hyaline cartilage is to provide the flexibility to the bones or the components containing these two cartilages. As they are soft tissues with resilient activity they help in providing the proper support for the bones which undergo continuous movement.
