7 wrz 2024 · Learn the definitions and examples of various movements of the body, such as flexion, extension, rotation, pronation and supination. Supination is the movement of turning the hand onto its back, palm up, while pronation is the opposite.
Supination is the opposite motion, in which rotation of the radius returns the bones to their parallel positions and moves the palm to the anterior facing (supinated) position. It helps to remember that supination is the motion you use when scooping up soup with a spoon (see Figure 4).
Definition. Supination is a rotational movement of the forearm at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints. When the arms are unbent and at the sides, the forearm is in supination when the palm faces to the front (anteriorly), or faces up.
Supination is a rotational movement of the forearm that positions the palm of the hand face up or forward. It occurs at the radioulnar joint and is opposite to pronation, which turns the palm down or backward.
Definition. Supination and pronation of the hand are rotational movements which occur at the superior radioulnar joint. These rotational movements are facilitated due to the presence of an annular ligament which holds the upper end of the radius in close apposition with the ulna.
Supination, in contrast, is a combined movement of inversion, adduction, and plantar flexion of any region of the ankle and foot (Fig. 11.8B). As indicated in this figure these specialized movements occur most regularly at the subtalar and transverse tarsal joints.
