synovial joints

Question 1

Synovial joints

Answer 1

Synovial joints are characterised by having a fluid-filled space between smooth cartilage pads at the end of the bones that form the joint. Surrounding the joint is a tough joint capsule that is lined with a synovial membrane.
The outer layer of capsule often includes ligaments that join bones to bones and strengthen the joint to prevent unnecessary movements and possible dislocations. The synovial membrane lining the capsule produces an oily synovial fluid that lubricates the joint and reduces friction and wear.
In addition to the joint capsule and ligaments that support a synovial joint, there are several important structures surrounding the joint that help cushion and protect the joint from friction and outside forces. Small bags of synovial fluid, known as bursae, surround the joint to reduce the friction from movement of tendons across the surface of the joint.
There are many different classes of synovial joints in the body, including hinge joints and ball and socket joints.
