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).
There is, of course, a connection between the structure of a joint and the degree of movement of the bones it allows. It is useful to know the words used to refer to and describe different classes of types of joints-see the table below.Some practical courses concentrate on the structural types (or classes) of joints. types of movable joints. 1  Hinge, e.g. interphalangeal joints-fingers and toes. 2  Ball and socket, e.g. hip and shoulder joints. 3  Pivot, e.g. atlantoaxial joint between the atlas and axis-neck. 4  Gliding (=  Condyloid  joint), e.g. between radius, scaphoid and lunate bones-wrist.
