The "right arm" refers to the limb on the right side of the human body, extending from the shoulder to the hand. It consists of several parts, including the upper arm, forearm, wrist, and hand. The right arm is typically used for tasks that require precision and strength, such as writing or lifting objects. In many cultures, the right arm is associated with positive actions and is often used for greeting others, such as in a handshake. The right arm is controlled by the left hemisphere of the brain, which is responsible for motor skills and coordination.
