Summary Introduction

To write:

Two types of joint conditions.

Introduction:

A point where two bones meet or join is known as joints. Joints are classified based on the structure and the movement they can allow. There are five types of joints in the human body. They are ball and socket, pivot, hinge, gilding and sutures.

Explanation of Solution

Arthritis is a pain and inflammation in a joint.

The two joints conditions are -:

1. Osteoarthritis: it is the most common arthritis type that occurs in humans. In this type of arthritis, wear and tear occur in the joint with the increasing age. Cartilages that provide a cushion to joints break down with the time which results in stiffness and pain while moving. Walking for a person with osteoarthritis becomes very difficult due to stiffness and pain. Osteoarthritis occurs in a person with the age of above 50. Women are more vulnerable to this type of arthritis.
2. Rheumatoid arthritis: this type of immune is an autoimmune type of disease. In this type of joint, the lining of the joints gets affected. Cells of the immune system which doesn’t belong to the joints accumulate at joints in large number. This immune cell interacts with joint cells and causes inflammation which results in damage and destruction of bone and cartilages present at the joints.

Conclusion

The two joint conditions that occur in the human body are osteoarthritis and rheumatoid arthritis.
