PROPERTIES AND FUNCTIONS.
1 The cartilages are distinguished by their great thickness and solidity, which enables them to resist force applied during various articulations. They are also characterized by their elasticity, on which property their specific use in the economy depends.
The vital properties are very obscure in this system, but we cannot therefore suppose that cartilages arc dead or inorganic substances. They are not capable of contracting, and it is probable that they do not possess animal sensibility in the state of health. They are, however, susceptible of painful impressions when they are irritated in an unusual manner; there is an instance of this in the severe suffering which is occasionally experienced from the presence of loose bodies in the joints.
The functions of these organs depend, like those of the osseous system, with which they are closely united, on their physical properties. Their elasticity allows them to yield in the shocks to which the body is exposed, in the ever varying movements of the animal frame; and in this manner they defend the bones from fracture and displacement, and at the same time protect the great centres of the nervous system from those injurious concussions to which they would otherwise be liable. In this important office, which is almost their sole use, they are frequently assisted by some of the bodies included in the fibro-cartilaginous system. The costal cartilages powerfully assist in expiration, in consequence of their elastic reaction depressing the ribs when the contraction of the inspiratory muscles ceases.

Key Takeaways
- Cartilages are vital for joint protection and movement
- Their elasticity helps in shock absorption during physical activity
- Loose bodies in joints can cause severe pain
Practical Tips
- Understand the importance of maintaining cartilage health to prevent joint injuries.
- Be cautious about activities that could irritate or damage your cartilages, such as excessive weightlifting without proper form.
Warnings & Risks
Risk
Irritation from loose bodies in joints can lead to severe pain and discomfort.
Warning
Avoid activities that could cause unusual irritation or damage to your cartilages, as this may lead to painful conditions.
## Modern Application
While the chapter provides insights into the properties and functions of cartilages, modern medical practices have advanced significantly in understanding and treating joint issues. However, the fundamental principles of maintaining healthy joints through proper movement and avoiding injury remain crucial for survival preparedness.
## Frequently Asked Questions
**Q: What are the vital properties of cartilages mentioned in this chapter?**
The vital properties of cartilages, as mentioned, are their great thickness and solidity, which enable them to resist force applied during various articulations. They also possess elasticity, which is crucial for their specific use in the economy.
Q: How do cartilages protect bones from injury?
Important
Cartilages defend bones from fracture and displacement by yielding to shocks and protecting the nervous system from concussions. This is their primary function, which they perform through their elasticity.
Q: What happens when cartilages are irritated in an unusual manner?
