Verified step by step guidance

Step 1: Begin by understanding the term 'synarthrosis.' Synarthrosis refers to a type of joint classification based on its functional movement. Functional joint classifications include synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable).
Step 2: Recall that synarthrosis joints are designed to provide stability rather than movement. These joints are typically found in areas where movement is not required, such as the sutures of the skull.
Step 3: Compare synarthrosis with other functional joint types. Amphiarthrosis joints allow slight movement, such as the intervertebral discs, while diarthrosis joints are freely movable, like the shoulder or hip joints.
Step 4: Eliminate the incorrect options based on the definition of synarthrosis. Slightly movable, capable of rotation, and freely movable do not align with the immovable nature of synarthrosis joints.
Step 5: Conclude that the correct answer is 'immovable,' as this is the defining characteristic of synarthrosis joints.
