Quadriceps femoris muscle

Quadriceps femoris muscle

Beginning:

1. m. rectus femoris - spina iliaca anterior inferior; (caput rectum et caput reflectum)
2. m. vastus medialis − labium mediale lineae asperae;
3. m. vastus intermedius - front surface of the femur, distal to the linea intertrochanterica; part of the muscle fibers is clamped directly into the joint sheath, thus preventing it from twisting - m. articularis genu
4. m. vastus lateralis − labium laterale lineae asperae and linea intertrochanterica - its proximal part

Attachment: tuberositas tibiae (ligamentum patellae)

Innervation: n. femoralis (from L₂−L₄)

1. hip joint − flexion;
2. knee joint − extension.
