The flexor digitorum longus tendon allows for curling the ends of the toes. It originates in the calf and runs down the back of the leg to connect to the underside of the toes, enabling flexion at the toe joints.
Wind stress curl is a measure of the twisting or rotational effect of wind stress on the surface of the ocean. It represents the change in the horizontal wind stress field with respect to direction, indicating the tendency for water to converge or diverge in the surface layer. Positive wind stress curl leads to convergent flow and downwelling, while negative wind stress curl leads to divergent flow and upwelling.
Calla lily stems curl in water due to a phenomenon called thigmotropism, where plant stems respond to touch or contact. When placed in water, the stems can bend or curl as a natural response to the change in environment and the pressure exerted by the water.
Knee extension is primarily a sagittal plane movement that involves extension of the knee joint, resulting in straightening of the leg. It does not involve any specific type of rotation.
