Verified step by step guidance

Step 1: Understand the concept of joint classification. Joints are categorized based on their movement capabilities: uniaxial (movement in one plane), biaxial (movement in two planes), and multiaxial (movement in multiple planes).

Step 2: Review the anatomy of the shoulder joint. The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint that allows movement in multiple planes, including flexion/extension, abduction/adduction, and rotation.

Step 3: Compare the shoulder joint to other joints listed in the problem. For example, the interphalangeal joints are uniaxial (allowing flexion and extension only), the knee joint is primarily biaxial (allowing flexion/extension and slight rotation), and the elbow joint is uniaxial (allowing flexion and extension).

Step 4: Recognize that the shoulder joint is the only multiaxial joint among the options provided, as it allows movement in three planes and axes.

Step 5: Conclude that the correct answer is the shoulder joint, based on its anatomical structure and movement capabilities.
