Definition:

Cartilage is a flexible connective tissue.

Characteristics:

It is composed of specialized cells called chondrocytes.

It is rubbery, smooth, and firm, providing support and shock absorption.

It has a limited capacity for self-repair due to a lack of blood vessels.

Types:

Hyaline cartilage is the most common type and is found in the nose, trachea, and ends of long bones.

Elastic cartilage is more flexible and is found in the outer ear and larynx.

Fibrocartilage is the toughest type and is found in the intervertebral discs and knee joints.

Functions:

Cartilage provides structural support to the body, maintaining the shape of various organs.

It acts as a cushion between bones, reducing friction and preventing damage from excessive stress.

It aids in the smooth movement of joints and allows for flexibility and elasticity.

It serves as a model for bone formation during embryonic development.

Importance:

Cartilage plays a vital role in the overall functioning and maintenance of the skeletal system.

It helps ensure the proper growth and development of bones, joints, and other connective tissues.
