A pivot joint (trochoid joint, rotary joint, Lateral Ginglymus) is a type of synovial joint.In pivot joints, the axis of a convex articular surface is parallel with the longitudinal axis of the bone.ivot joints allow for rotation, protraction, retraction,twist, flexion, extension, adduction and abduction, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward). When rotating the forearm, these movements are typically called pronation and supination.
There are many muscles that are responsible for primary body movements during exercise. They sometimes work in pairs; when one contracts, the opposite muscle stretches to allow a motion to occur. Other times, the muscle that causes a primary motion may part of a group of muscles that perform a similar function.The primary muscle is directly responsible for the movement while the others play an indirect, supporting role. It is not uncommon for one muscle to play an important role in more than one movement.here are also numerous muscles needed to move the torso during exercise to produce the full extent of movement in this region of the body. The erector spinae muscles of the back and the rectus abdominus of the front of the torso are primarily responsible for bending forward and backward.
