MUSCLES THIGH:
The thigh muscles can be watered in 3 regions:
- Anterolateral Region
- Later Region
- Posteromedial Region
Anterolateral Region | Later Region | |

Femoral Biceps Semitendinous Semimembranaceous |
Post-Medial Region |
Free Pectinous Long Adductor Short Adductor Adductor Magno |
Anterolateral Region
1. CAN FASIA TENSOR

2. SARTORY
Proximal Insertion: Anterior superior iliac spine
Distal Insertion: Medial surface of the tibial tuberosity (goose paw)
Innervation: Femoral Nerve (L2 & #8211; L3)
Action: Flexion, Abduction and Lateral Rotation of the Thigh and Flexion and Medial Rotation of the Knee

3. FEMORAL QUADRICE
Proximal Insertion:
Previous Straight: Anterior inferior iliac spine
Vastus lateralis: Greater trochanter, rough line, intertrochanteric line and gluteal tuberosity
Vast Medial: Rough Line and Intertrochanteric Line
Vast Intermediate: 2/3 proximal to anterior and lateral femur and ½ distal to rough line
Distal Insertion: Patella and, through the patellar ligament, in the anterior tibial tuberosity
Innervation: Femoral Nerve (L2 & #8211; L4)
Action: Knee Extension and Femoral Rectum perform Hip Flexion. The vastus medialis performs medial rotation and the vastus lateralis performs lateral rotation
Later Region
