Verified step by step guidance

Step 1: Begin by understanding the term 'articulations,' which refers to joints where two or more bones meet. Joints are classified based on their structure and the degree of movement they allow.
Step 2: Review the classification of joints based on movement: Synarthroses are immovable joints, Amphiarthroses allow slight movement, and Diarthroses are freely movable joints.
Step 3: Synovial joints are a type of structural classification and are typically associated with diarthroses, which allow free movement. This eliminates 'synovial joints' as the correct answer for slight movement.
Step 4: Synarthroses are immovable joints, such as sutures in the skull. Since the problem specifies 'slight degrees of movement,' synarthroses can also be eliminated.
Step 5: Amphiarthroses are joints that permit slight movement, such as the intervertebral discs or the pubic symphysis. This matches the description in the problem, making 'amphiarthroses' the correct answer.
