D
Amphiarthroses
Verified step by step guidance
1
Step 1: Understand the functional classification of joints. Joints are classified based on their movement capabilities into three categories: synarthroses (immovable), amphiarthroses (slightly movable), and diarthroses (freely movable).
Step 2: Recall the definition of amphiarthroses. These joints allow slight movement and are typically found in areas like the intervertebral discs and the pubic symphysis.
Step 3: Compare the other options provided in the question. Synovial joints are structurally classified and are associated with diarthroses (freely movable joints). Synarthroses are immovable joints, such as sutures in the skull. Diarthroses are freely movable joints, such as the shoulder or knee.
Step 4: Eliminate incorrect options based on their definitions. Synovial joints and diarthroses are associated with free movement, while synarthroses are immovable. None of these match the description of slight movement.
Step 5: Conclude that the correct functional classification for joints with slight movement is amphiarthroses, as it matches the definition provided in Step 2.
