The thigh is the part of the leg located between the hip and the knee. It is made up of several muscles, including the quadriceps at the front and the hamstrings at the back. These muscles are essential for movements such as walking, running, and jumping. The thigh also contains important structures like blood vessels and nerves. The femur, which is the longest bone in the body, runs through the thigh. This area plays a crucial role in supporting the body's weight and facilitating movement, making it vital for daily activities and physical exercise.
