Understand the definition of a joint cavity: A joint cavity is a space between the articulating bones of a synovial joint, filled with synovial fluid, which allows for movement and reduces friction.
Identify the types of joints: Synovial joints have a joint cavity, while fibrous joints (such as sutures and gomphoses) and cartilaginous joints do not.
Examine the given options: Sutures between skull bones and gomphoses are fibrous joints, which do not have a joint cavity.
Consider the knee joint: The knee is a synovial joint, characterized by the presence of a joint cavity filled with synovial fluid, allowing for a wide range of motion.
Evaluate the distal joint between the tibia and fibula: This is a syndesmosis, a type of fibrous joint, which does not have a joint cavity.
