Answering the Question

The biggest muscle in terms of mass in the human body is the gluteus maximus. This muscle is located in the buttock region and plays a crucial role in various movements such as hip extension, outward rotation, and maintaining the trunk's stability during activities like walking, running, and climbing.

To provide context, here’s a brief description of the options:

1. Gluteus maximus: This is the largest muscle in the body, responsible for the shape of the buttocks and significant in leg movements.

2. Sartorius: This is the longest muscle but relatively small in mass and assists in flexing, abducting, and laterally rotating the hip.

3. Stapedius: The smallest muscle in the body, located in the middle ear, controlling the stapes bone's movement, it has minimal impact on overall body mass.

4. Quadriceps femoris: A group of four muscles at the front of the thigh important for leg extension, but their collective mass is less than that of the gluteus maximus.

5. Latissimus dorsi: A large muscle in the back that helps with arm movements but does not surpass the gluteus maximus in size.

Thus, among these options, gluteus maximus is the correct answer as it holds the title for the biggest muscle by mass in the human body.
