The Quadriceps femoris is a group of four muscles located in the anterior thigh, including the Rectus femoris, Vastus lateralis, Vastus medialis, and Vastus intermedius. It is primarily responsible for extending the knee.

Front

What is the Vastus lateralis?

Back

The Vastus lateralis is one of the four muscles of the quadriceps femoris group, located on the outer side of the thigh. It plays a key role in knee extension.

Front

What is the Vastus medialis?

Back

The Vastus medialis is one of the four muscles of the quadriceps femoris group, located on the inner side of the thigh. It helps stabilize the patella and is important for knee extension.

Front

What is the Vastus intermedius?

Back

The Vastus intermedius is one of the four muscles of the quadriceps femoris group, located beneath the Rectus femoris. It is involved in knee extension.

Front

What is the Sartorius?

Front

What role does the Rectus femoris play in hip movement?

Back

The Rectus femoris assists in hip flexion in addition to its primary role in knee extension.

Front

How does the Vastus medialis contribute to knee stability?

Back

The Vastus medialis helps stabilize the patella during knee movements, preventing lateral tracking and ensuring proper alignment.
