While studying with your lab partner, he says that synovial joints are functionally classified as synarthroses. Explain how his statement is incorrect, and then correct his statement
What will be an ideal response?
Synovial joints are not functionally classified as synarthroses. Synovial joints are the only structural class of joints to possess a joint space, or cavity, between articulating bones. It is the presence of this cavity, and other supportive structures, that allow this joint class the greatest motion of any joint type. Your lab partner should have stated that synovial joints are functionally classified as diarthroses since synarthroses do not allow any movement between articulating bones. Alternately, your lab partner could have stated that some fibrous joints and some cartilaginous joints are functionally classified as synarthroses.
