Bursae
- located between skin and bones, tendons and bones, muscles and bones, or ligaments and bones
- Main function: reduce friction between joints
Joint Capsule
- surrounds a synovial joint and encloses the synovial cavity
- Main function: unite the articulating bones and reduce friction via production of synovial fluid

TaigaA bursa is a fluid-filled sac that acts as a cushion between bones, tendons, and muscles to reduce friction and allow smooth movement. The joint capsule, on the other hand, is a fibrous structure that surrounds a joint and helps stabilize it by maintaining its structural integrity. While bursae reduce friction in specific areas, joint capsules provide overall support and protection to the entire joint.

What is bursa surface fraying?
Bursa surface fraying refers to degeneration or wear and tear of the bursa, a small fluid-filled sac that acts as a cushion between bones and tendons near a joint. This condition can cause pain, swelling, and inflammation in the affected area, impacting joint movement and function. Treatment may include rest, ice, anti-inflammatory medications, and physical therapy.
What is capsular damage?
Capsular damage refers to an injury or impairment of the joint capsule, a structure made up of ligaments that surrounds and stabilizes a joint. This can occur due to trauma, injury, or overuse, leading to pain, swelling, and limited joint mobility. Treatment typically involves rest, physical therapy, and in severe cases, surgery may be needed to repair the damaged capsule.
Fluid filled sacs in the knee?
The fluid-filled sacs in the knee are called bursae. They help reduce friction between moving structures in the joint. Inflammation of these bursae can lead to a condition called bursitis, causing pain and swelling in the affected area.
What is the difference between a mobile joint and rigid joint?
A mobile joint allows for movement between connected bones, while a rigid joint does not allow for movement. Mobile joints are found in areas like the shoulders and hips, whereas rigid joints are found in areas like the skull.
What is the type of joint found between the first and second vertebrae of the neck region or the backbone?
The type of joint found between the first and second vertebrae of the neck region, or the backbone, is called the atlantoaxial joint. It allows for rotation and flexion of the neck.
