Legs are the paired lower limbs of the human body that extend from the hips down to the feet. Each leg consists of several key parts: the thigh (containing the femur, the longest bone in the body), the knee joint, the lower leg (comprising the tibia and fibula bones), the ankle, and the foot. Legs are essential for supporting the body’s weight and providing mobility, enabling activities such as standing, walking, running, jumping, and climbing. They are powered by a complex system of muscles, tendons, ligaments, and nerves that work together to facilitate movement and maintain balance. The joints in the legs, especially the hips, knees, and ankles, allow for a wide range of motion and flexibility. In addition to their physical functions, legs play a role in posture and non-verbal communication, such as body stance and gestures.

Would you like me to include details about any specific part of the legs?
