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.

There are three types of joints: 1  Synovial joints â These joints are the most common type of joint, and they provide free movement between the bones they link. 2  They are typical of nearly all limb joints, such as the knee, elbow and wrist.
