Sagittal with a Medial Lateral axis
saggital
shoulder horizontal flexion
Flexion
horizontal plane
It is polarized at 90 degrees to the plane of incidence. If the surface is horizontal, the plane of incidence is vertical & the polarization would be horizontal.
Thumb abduction and adduction is in the sagittal plane. However, finger abduction and adduction is in the frontal/coronal plane. Do these movements in the anatomical position and that will help you see that the thumb is not abducting or adducting in the frontal plane rather the sagittal plane.
A flexion preformed across the horizontal plane.
Lateral flexion of the trunk involves moving the shoulders left or right towards the hips, therefore it is exercised in the frontal or coronal plane of motion.
linear motion
The Sagittal plane passes through the body front to back, so dividing it into left and right. Movements in this plane are the up and down movements of flexion and extension.
horizontal/trasverse
Simply stated, flexion is when the angle around a joint is decreased from it's normal position (from the anatomical position) in the SAGITTAL plane. The sagittal plane is an imaginary line that splits your body into left and right pieces. All flexion moves in this plane. Ex. Flexion of the bicep requires you to pull your forearm (decrease the angle) toward your head. That motion running along the side of your body is also in the sagittal plane
They are hinge joints. The elbow has only one plane of motion (flexion & extension); however, the knee is considered a "modified hinge" because it has the flexion & extension as well as a rotational (pivot) component as well.
Though flexion and extension can occur in a variety of planes depending on the body's position, if you have a body in anatomical position, then all flexion and extension occurs on the sagittal plane.
sagitall (side view) just think if you had a video camera on the side of someone you would see movement take place from this view
shoulder horizontal flexion
Grass is rough, it stood tall from ground against the motion moving in horizontal plane. What that act against the motion is friction.
Its shape. It has vertical and horizontal stabilisers that, because the air plane iis always in motion, keep it stable. They are also used for navigating the plane.
