Diarthrotic Joints

Diarthrotic joints are synovial joints that allow expansive movement, giving the most range of motion possible. But on the negative side, with more movement, means less stable joints, for example the shoulder is very unstable, but allows a lot of expansive movement. The types of diarthrotic joints are below:

Anatomical Movements

Anatomical movements, are the movements allowed by the diarthrotic joints. The amount of movement allowed is based on the joint the movement is taking place. There are 18 different types of anatomical movements involving the flexing of muscles and movement of bones. They can be found below:

Anatomical Positions

Anatomical positions are a group of opposing terms that are used to help compare body parts to each other, and body parts to planes and imaginary lines on the body. Using these terms help people determine exactly where something is located. The eight main terms can be found below:

Anatomical Planes

The last group of kinesiology terms is anatomical planes. These planes are used to divide the body so that someone can be more specific with where on the body they are talking about. There are three planes that divide the body in half all three ways - front to back - left and right - and bottom and top. These are described in more depth below:
