Manipulated variable is usually a measure, a variable that you can measure. For example, if you can measure the voltage in the experimental setup then you can manipulate it, like using it to power a device. Constant variable, i think this is not very correct, a mathematician's opinion might be needed.
A synovial joint, also known as diarthrosis, is the most common and most movable type of joint in the body of a mammal. As with most other joints, synovial joints achieve movement at the point of contact of the articulating bones.Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses).s with most other joints, synovial joints achieve movement at the point of contact of the articulating bones.

Ball and socket joints allow for stable movement in several directions without slippage. Like a saddle joint, the ball and socket joint allows bending in several directions without slipping, creating a highly stable, strong joint. The hip joint (femur-acetabulum) is an example of a ball and socket synovial joint.here are six types of synovial joints: gliding, condoloid, saddle, hinge, ball and socket, and pivot joints. Gliding joints allow for smooth movement in several directions along a plane or other smooth surface.
