Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity of bone shafts where red and yellow bone marrow is stored.

Front

What are synovial joints?

Back

Synovial joints are joints that are characterized by a fluid-filled joint cavity, allowing for a wide range of motion.

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

Front

What is the role of the synovial membrane?

Back

The synovial membrane lines the joint capsule and secretes synovial fluid.
