Question

Describe the key features of a synovial joints. Ch 9 obj 25

Answer 1

Synovial joints have key features including a joint cavity, articular capsule, articular cartilage, synovial fluid, and ligaments.

Step-by-step explanation:

Synovial joints are the most common type of joint in the body. They have several key features:

1. The presence of a joint cavity, which is a fluid-filled space where the articulating surfaces of the bones contact each other.
2. An articular capsule that surrounds the joint and defines the joint cavity.
3. An articular cartilage that covers the surfaces of the bones, reducing friction between them.
4. Synovial fluid, which is secreted by the synovial membrane and lubricates the joint.
5. Ligaments, which support the joint by holding the bones together and resisting excess or abnormal joint motions.
