Detailed explanation-1: -The quadriceps femoris is a hip flexor and a knee extensor. It consists of four individual muscles; three vastus muscles and the rectus femoris. They form the main bulk of the thigh, and collectively are one of the most powerful muscles in the body. It is located in the anterior compartment of the thigh.

Detailed explanation-2: -The quadriceps are a group of muscles present on the front of the thigh. They consist of four distinct muscles: the rectus femoris, the vastus lateralis, the vastus intermedius, and the vastus medialis.

Detailed explanation-3: -The hip flexors consist of 5 key muscles that contribute to hip flexion: iliacus, psoas, pectineus, rectus femoris, and sartorius.

Detailed explanation-4: -The rectus femoris is the only quadriceps muscle that traverses both the hip and the knee joint. The rectus femoris is a powerful hip flexor, but it is largely dependent on the position of the knee and hip to assert its influence.
