This or related words may also be used to describe the action of certain muscles that cause such movement. These movements are hip flexion, extension, adduction, abduction, and rotation. External or lateral rotation of the arm represents the movement of the humerus when an arm flexed to 90° at the elbow is externally rotated around the longitudinal plane of the humerus such that the hand moves away from the midline of the body. Protraction – anterior projection of a body part (sticking out the jaw is an example) Retraction – direct … Medial and lateral rotation or arm is associated with similar rotation of the spine. • An object and its rotation are the same shape and size, but the figures may be turned in different directions. 3 Primary Axes of Rotation 1.

When an individual presses the back of the hand against… rotation on axis of bone, specifically applied to forearms, as in turning hand up by rotating the radius on the ulna horizontal flexion (adduction) movement of the humerus from the side-horizontal to the front-horizontal position Hip muscles are skeletal muscles that enable the broad range of motion of the ball and socket joint of the hip. n. 1. External rotation (or lateral rotation) is rotation away from the centre of the body. What does rotation mean? The anterior head of the deltoid works closely with pectoralis major, which allows for full stabilization near its more superior insertion on the clavicle. A rotation is a transformation that turns a figure about a fixed point called the center of rotation. Free learning resources for students covering all major areas of biology. Pronation: Rotation of the forearm and hand so that the palm is down (and the corresponding movement of the foot and leg with the sole down), as opposed to supination. Medial rotation is a term describing a specific anatomical motion. When working in the coordinate plane: • assume the center of rotation to be the origin unless told otherwise. Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.Terms used generally derive from Latin or Greek roots and used to describe something in its standard anatomical position.This position provides a standard definition of what is at the front ("anterior"), behind ("posterior") and so on. • Rotations may be clockwise or counterclockwise.
