rectus femoris

Musculus rectus femoris

In 3 atlases

Quadriceps femoris comprises four muscles in the front of the thigh that share a tendon and extend the knee.
Rectus femoris crosses both the hip and knee, whereas the three vastus muscles cross the knee only.
The quadriceps tendon attaches to the patella, and the patellar ligament continues to the tuberosity of the tibia.
All four muscles receive their motor supply from the femoral nerve.
The atlas entry is anchored to rectus femoris, which is one component of quadriceps femoris rather than a name for the whole group.
