Cartilage

Cartilage is a tough, flexible connective tissue found in many areas of the body. It provides support and cushioning for bones and joints, as well as maintaining the shape of certain body parts.

Types of Cartilage

1. Hyaline cartilage: Found in the nose, trachea, and the ends of long bones, providing a smooth surface for joints.
2. Elastic cartilage: Contains elastic fibers and is found in the external ear and parts of the larynx.
3. Fibrocartilage: Contains strong collagen fibers and is found in the intervertebral discs and the knee joint, providing strength and support.

Functions of Cartilage

• Provides cushioning and support for joints
• Helps maintain the shape of the nose, ears, and other body parts
• Allows for smooth movement of bones at joints

Study Guide

Here are some key points to remember about cartilage:

Structure:

Cartilage is a tough, flexible connective tissue made up of cells called chondrocytes and a gel-like matrix.

Types:

There are three main types of cartilage: hyaline, elastic, and fibrocartilage.

Functions:

Cartilage provides cushioning and support for joints, helps maintain the shape of certain body parts, and allows for smooth movement of bones at joints.

Remember to review the locations and functions of each type of cartilage, as well as its overall importance in the body's structure and movement.

Now that you have a solid understanding of cartilage, you're ready to ace your science studies!
