Answer

To determine the longest individual muscle in the human body, we can analyze the options provided: quadriceps femoris, gluteus maximus, sartorius, and latissimus dorsi.

1. **Understanding the Options**:
- **Quadriceps Femoris**: This is a group of four muscles located at the front of the thigh. While they are among the largest and strongest muscles, they are not a single muscle.
- **Gluteus Maximus**: This is the largest muscle in the human body, but it is not the longest.
- **Sartorius**: This is a long, thin muscle that runs down the length of the upper thigh and crosses the leg down to the inside of the knee.
- **Latissimus Dorsi**: This is the widest muscle in the body, but again, not the longest.

2. **Identifying the Longest Muscle**:
- The sartorius muscle is known to be about 50 cm in length, making it the longest individual muscle in the human body.

3. **Conclusion**:
- After analyzing all the options, we conclude that the longest individual muscle in the human body is **sartorius**.

**Final Answer**: Sartorius
