⭐ Quadriceps Muscle Anatomy ⭐
The quadriceps muscle consists of four muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. Dive into the anatomy of each muscle below and watch the full video for an indepth explanation.

Origins & Insertions:
✔ Rectus Femoris:
Origin (Direct head): Anterior inferior iliac spine
Origin (Indirect head): Acetabular ridge
Insertion: Tibial tuberosity via patellar ligament & quadriceps tendon

✔ Vastus Lateralis:
Origin: Greater trochanter, intertrochanteric line, linea aspera, gluteal tuberosity, lateral intermuscular septum
Insertion: Lateral aspect of the patella & tibial tuberosity (via patellar ligament & quadriceps tendon)

✔ Vastus Medialis:
Origin: Intertrochanteric line, spiral line (pectineal line), linea aspera, medial supracondylar line, adductor longus muscle, adductor magnus muscle, & medial intermuscular septum
Insertion: Medial border of patella, & tibial tuberosity (via patellar ligament & quadriceps tendon)

✔ Vastus Intermedius:
Origin: Anterior and lateral surface of the femur & lateral intermuscular septum
Insertion: Tibial tuberosity via patellar ligament & quadriceps tendon

Actions:
All muscles: Extends the knee joint and stabilises the knee joint
Rectus Femoris: Flexes the hip joint

Nerve:
All muscles: Femoral nerve (L2, L3, L4)

Artery:
All muscles: Femoral artery
