horizontal/trasverse
transverse 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.
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.
Rotational motion is rotation of a body about its center of mass.
Rotation is the circular motion of a body around a central axis.
Revolution is the motion of a body that travels around another body in space;one complete trip along an orbit. Rotation is the spin of a body on its axis.

Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
Rotation around a point, or spherical motion, is the motion of a rigid body during which one of its points O remains fixed, while all the other points move along the surface of spheres with their center at point O. During such rotation of a rigid body, any elementary displacement of the body is an elementary rotation around some axis passing through point O and called the instantaneous axis of rotation. This axis, unlike a fixed axis, is constantly changing its direction with time. As a result, the rotational motion of a rigid body consists of a series of elementary rotations about instantaneous axes that are constantly changing direction. An example of such rotation is the movement of a gyroscope.
closer to the origin of the body part or the point of attachment of a limb to a body trunk. For example, The elbow is proximal to the wrist
Direct motion is the motion of planetary body in a direction similar to that of other bodies within its system, and is sometimes called prograde motion. Retrograde motionis motion in the opposite direction.
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
