Hands are the multi-fingered extremities at the end of human arms. They consist of a palm, fingers, and a thumb, allowing for a wide range of movements and functions. Each hand typically has five fingers, which include the thumb, index finger, middle finger, ring finger, and little finger. The structure of hands includes bones, muscles, tendons, and skin, enabling tasks such as grasping, holding, and manipulating objects. Hands play a crucial role in daily activities and communication. They are essential for tasks like writing, cooking, and using tools. Additionally, hands are important for non-verbal communication, as gestures and sign language can convey messages without spoken words.
