Where are the largest skeletal muscles located and what is their job?

The largest skeletal muscles in the human body are located in the thighs, specifically the quadriceps at the front and the hamstrings at the back. These muscles are responsible for powerful movements such as walking, running, and jumping, as they facilitate the extension and flexion of the knee joint. Additionally, the gluteus maximus, also among the largest skeletal muscles, plays a crucial role in hip movement and maintaining upright posture. Together, these muscles support locomotion and overall mobility.
