Abduction is when a body part moves away from the midline.
Adductors
Joints don't have the ability to move. Joints are where two or more bones meet. One end of muscle attaches to the bone and the other end of the muscle stretches cross the joint and attaches to the bone on the other side of the joint. Muscles work in pairs, so that when one muscle contracts (the only movement that muscle can make), the other of the pair relaxes which causes movement at the joint when the bone is pulled by the muscle.
The movement permitted by a hinge joint is extension (opening) or flexion (closing). The elbow is a hinge joint. When you "flex your muscle", you preform a flexion movement (closing). The opposite is extension as in handing a cup to someone..
This is a saddle joint which allows movement in two planes instead of one. It allows the thumb to cross the palm of the hand. This joint allows biaxial movement. This allows movement in the frontal and sagittal planes.
Peroneal group of muscles are involved in eversion joint movement. This compartment lies lateral side of leg. These muscles are supplied by common peroneal nerve.
a muscle which crosses a single joint refers to a single joint muscle.

By tensing.
Any nerve serving a muscle that produces a movement at a joint does innervate the joint and the skin over the joint.
No, the fluid becomes thinner as movement increases enabling it to thoroughly lubricate the joint while movement occurs.
This can be answered on several different levels, but let me take the simpliest.Major types of muscles:Skeletal - associated with bones - see more info below.Cardiac - muscle of the heart specializing in electrical communicationViseral or Smooth - lines all tubes and has the movement called peristalsisSkeletal Muscle movement associated with diarthritic joints: Hinge Joint - movement is extension or flexionCondyloid Joint - movement is pronation or supinationBall & Socket Joint - abduction & adduction are the first of many movements.Pivot Joint - movement is rotationAnd the list goes on. . . .

A synergist muscle is a muscle that aids another by promoting the same movement.
The synergist muscle performs the same movement as the primary mover. This often depends of the position of the joint.
This is a saddle joint which allows movement in two planes instead of one. It allows the thumb to cross the palm of the hand. This joint allows biaxial movement. This allows movement in the frontal and sagittal planes.
