'Diarthrosis' is the broad category of freely movable synovial joints (e.g., hinge, ball-and-socket, pivot). 'Arthrodia' is a specific type of diarthrosis characterized by flat surfaces and gliding movement.
Yes. The joints between the individual carpal bones in your wrist (e.g., between the scaphoid and lunate) are arthrodias. The joints between the tarsal bones in your ankle are another example.
Yes. The adjective is 'arthrodial', as in 'arthrodial joint' or 'arthrodial movement'.
