Verified step by step guidance

Step 1: Understand the structural classification of joints. Joints are categorized based on their structure, which refers to how the bones are connected. The three main structural classifications are fibrous, cartilaginous, and synovial.
Step 2: Define each structural classification: Fibrous joints are connected by dense connective tissue and allow little to no movement (e.g., sutures in the skull). Cartilaginous joints are connected by cartilage and allow limited movement (e.g., intervertebral discs). Synovial joints have a fluid-filled cavity and allow a wide range of movement (e.g., the knee joint).
Step 3: Recognize that 'muscular' is not a structural classification of joints. Muscles are involved in movement but are not part of the structural classification system for joints.
Step 4: Compare the given options to the structural classifications. Fibrous, cartilaginous, and synovial are valid structural classifications, while muscular is not.
Step 5: Conclude that the correct answer is 'muscular,' as it does not fit within the structural classification of joints.
