Verified step by step guidance

Understand the classification of joints based on their movement capabilities. Joints are categorized as uniaxial, biaxial, multiaxial, or synarthrotic depending on the number of axes or planes they allow movement along.

Review the definition of uniaxial joints: These joints allow movement along only one axis, such as flexion and extension. Examples include hinge joints (e.g., elbow) and pivot joints (e.g., atlantoaxial joint in the neck).

Contrast uniaxial joints with biaxial joints: Biaxial joints allow movement along two axes, such as flexion-extension and abduction-adduction. Examples include condyloid joints (e.g., wrist) and saddle joints (e.g., thumb).

Compare uniaxial joints with multiaxial joints: Multiaxial joints allow movement along three or more axes, such as rotation, flexion-extension, and abduction-adduction. Examples include ball-and-socket joints (e.g., shoulder and hip).

Understand synarthrotic joints: These joints are immovable and do not allow movement along any axis. Examples include sutures in the skull. Based on this comparison, uniaxial joints are the correct classification for joints allowing movement along only one axis.
