Final answer:
The 6 anterior thigh compartment muscles that do not flex the hip are rectus femoris, vastus intermedius, vastus lateralis, vastus medialis, sartorius, and tensor fasciae latae.
Step-by-step explanation:
The correct answer is a) Rectus femoris, vastus intermedius, vastus lateralis, vastus medialis, sartorius, tensor fasciae latae.
These six anterior thigh compartment muscles do not flex the hip. Instead, they primarily extend the leg at the knee and are part of the quadriceps femoris group.
For example, the rectus femoris is located on the anterior aspect of the thigh and is responsible for extending the leg at the knee.
