Cartilage

Cartilage is a flexible connective tissue found in various parts of the body. It is composed of specialized cells called chondrocytes, which are embedded in a matrix of collagen and proteoglycans.

Types of Cartilage

1. Hyaline Cartilage: Found in the nose, trachea, and at the ends of long bones.
2. Elastic Cartilage: Found in the outer ear and larynx.
3. Fibrocartilage: Found in the intervertebral discs and the knee joint.

Functions of Cartilage

Cartilage serves several important functions in the body, including:

• Providing a smooth surface for joint movement
• Acting as a shock absorber between bones
• Supporting the structure of the ear, nose, and trachea
• Aiding in the growth of long bones in children

Study Guide

When studying cartilage, it is important to understand its structure, types, and functions. Here are some key points to focus on:

1. Describe the structure of cartilage, including the composition of its matrix and the role of chondrocytes.
2. Identify the three types of cartilage and their locations in the body.
3. Explain the functions of cartilage and provide examples of how it supports various physiological processes.
4. Explore the role of cartilage in skeletal development and maintenance.
5. Compare and contrast the properties of hyaline, elastic, and fibrocartilage, highlighting their unique characteristics and functions.

Understanding the role of cartilage in the body is essential for appreciating its contribution to overall skeletal health and function.
