The respective knee flexes while the hip is extending, bringing the torso to the highest vertical position. The center of gravity moves laterally to the supporting-limb side. During mid-stance phase the reference foot contact the ground flat-footed. Heel Rise: The heel of the reference foot rises while the toes are still in contact with the ground.
Topspin in ball games is defined as spin about a horizontal axis perpendicular to the direction of travel that moves the top surface of the ball in the direction of travel. Under the Magnus effect, topspin produces a downward swerve of a moving ball, greater than would be produced by gravity alone.
Several factors can influence eye movement in scene viewing, including the task and knowledge of the viewer (top-down factors), and the properties of the image being viewed (bottom-up factors). Typically, when presented with a scene, viewers demonstrate short fixation durations and long saccade amplitudes in the earlier phases of viewing an image.
Lateral and anterior views of the extraocular muscles also showing common tendinous ring origin and trochlea. Since only a small part of the eye called the fovea provides sharp vision, the eye must move to follow a target. Eye movements must be precise and fast. This is seen in scenarios like reading, where the reader must shift gaze constantly.
Prokinesis, where the upper beak moves at the point where it is hinged with the bird's skull; Amphikinesis. Unlike prokinesis, the narial openings extend back almost to the level of the craniofacial hinge, and the dorsal and ventral bars are flexible near the symphysis. In addition, the lateral bar is flexible near its junction with the dorsal bar.
Lateral muscular branch of the ophthalmic artery: Nerve: Trochlear nerve: Actions: Primary action is intorsion (medial rotation); secondary actions are to abduct and depress the eyeball (i.e. it makes the eye move outward and downward) Identifiers; Latin: musculus obliquus superior bulbi: TA98: A15.2.07.016: TA2: 2048: FMA: 49039: Anatomical ...

When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre.
