Planes and Axes of Movement

Right now I am learning about the Planes and Axes of Movement. I find it hard and I tend to mix them up a lot so here it goes!

There are three different planes the Sagittal Plane, Frontal Plane, and Transverse Plane all which have perpendicular Axis which are the Anteroposterior Axis, Logitudinal Axis and Mediolateral Axis.

First the Planes:

Sagittal Plane: The Saggital Plane divides the body into right and left segments just like the photo below. How I like to think of it is just like the picture shows, cut your body into two right down the middle.

The Frontal Plane: The Frontal Plane divides the body into anterior and posterior segments. Shown in the picture below.

Anterior-situated at or directed toward the front.

Posterior-directed toward or situated at the back

Transverse Plane: The Transverse Plane divides the body into the upper and lower segments as shown in the picture below. Once again as if you are cutting your body into two.

Now on with the Axis: Like I said before all of the Axis are going to be perpendicular to one of the Planes, this helps me remember a little easier!

Anteroposterior Axis: The Anteroposterior Axis will always be perpendicular to the Sagittal Plane, which is where where abduction and adduction occur.

Abduction-Moving the distal segment to the side and away from the body anatomical position.

(Anatomical Position-is when the body is standing in erect position with your arms at the sides and palms are facing forward)

Adduction-is the return of the anatomical position from abduction, which is moving the segment in the opposite direction.

Here is a picture of Abduction and Adduction.

Mediolateral Axis: The Mediolateral Axis is perpendicular to the Sagittal Plane, which is where flexion and extension occur.

Flexion-is when you move the distal segment forward and upward in the anatomical position in order to bring two body segments closer together.

Extension– is when moving the segment in the opposite direction of flexion.

Here is a picture of Flexion and Extension:

Longitudinal Axis: Is perpendicular to the Transverse Plane, the internal and external rotation occur in this plane.

Internal Rotation-is when turning the segment toward the center of you body from the anatomical position.

External Rotation– is the turning the segment in the opposite direction of Internal, so the return motion.

Here is a picture of internal and external rotation.

Now here is a picture of all the Axis
