Verified step by step guidance

Understand the key terms: Synarthrosis joints are immovable joints, often tightly joined, such as those found in the skull. Diarthrosis joints, on the other hand, are freely movable joints, allowing a wide range of motion.
Recall the structural differences: Synarthrosis joints are typically connected by dense fibrous tissue, while diarthrosis joints are characterized by a synovial cavity filled with synovial fluid, which facilitates movement.
Consider the locations: Synarthrosis joints are commonly found in areas requiring stability, such as the skull sutures. Diarthrosis joints are found in areas requiring mobility, such as the shoulder, hip, and knee.
Analyze the options provided: Eliminate incorrect answers by matching the descriptions to the correct type of joint. For example, 'connected by dense fibrous tissue' and 'found only in the skull' describe synarthrosis joints, not diarthrosis joints.
Select the correct answer: Based on the characteristics of diarthrosis joints, the correct description is 'They allow free movement between bones.'
