Verified step by step guidance1
Understand the definition of a uniaxial joint: A uniaxial joint is a type of synovial joint that allows movement primarily around one axis.
Identify examples of uniaxial joints: Common examples include hinge joints like the elbow and pivot joints like the atlantoaxial joint in the neck.
Analyze the movement capabilities: Since uniaxial joints allow movement around one axis, they typically permit flexion and extension or rotation, depending on the joint type.
Compare with other joint types: Biaxial joints allow movement in two axes (e.g., wrist joint), and multiaxial joints allow movement in multiple axes (e.g., shoulder joint).
Conclude that in a uniaxial articulation, movement can occur in only one axis, which aligns with the definition and examples provided.
