Pronation
Turning the palm backward or downward is called pronation. This movement involves rotation of the forearm so that the palm faces downward or backward.
A movement that turns the palm downward is called pronation. This occurs when the forearm rotates, causing the palm to face downward or backward. Pronation is commonly involved in actions such as typing on a keyboard or pushing objects away. It contrasts with supination, where the palm faces upward.
Pronation is the motion that turns the palm of the hand downward or backwards. It involves rotating the forearm so that the palm faces posteriorly or downwards.

The term that means turning the palm upward or forward is "supination." This movement is commonly used in anatomy to describe the position of the forearm and hand. In contrast, the opposite movement, where the palm is turned downward or backward, is called "pronation."
The proper arm signal for slowing down while driving is to extend your left arm out of the window and point downward with your palm facing backward.
Commonly used bike hand signals for indicating turns include extending the left arm straight out to the side for a left turn, and bending the left arm at a 90-degree angle upward for a right turn. To indicate a stop, cyclists can extend the left arm downward with the palm facing backward.
Forearm rotation refers to the ability of the forearm to rotate around its longitudinal axis, primarily involving two movements: pronation and supination. Pronation is the rotation that turns the palm downward or backward, while supination turns the palm upward or forward. This movement is facilitated by the radius and ulna, the two bones in the forearm, which can cross over each other during rotation. Forearm rotation is essential for various daily activities, such as turning a doorknob or using utensils.
To indicate that you are braking while riding a bicycle, you should use your left hand to extend downward with your palm facing backward.
