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. Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses).
Synovial joints have a synovial cavity between the articulating bones. This cavity is filled with synovial fluid that reduces friction at the joint, enabling the articulating bones to move freely. The page about types of joints explains the 3 functional classes of joints: 1  synarthroses (immovable joints).ynovial joints are freely movable joints. A formal medical term is  diarthroses  but synovial joints are commonly described as simply  movable  or  freely movable . Most of the main joints of the appendicular skeleton (including the arms and hands, and the legs and feet) are synovial joints.
