Study Notes

Anatomy of the Hip and Thigh Muscles

  • Gluteus maximus is the largest and thickest muscle in the human body, functioning as an antagonist to the iliopsoas muscle.
  • Gluteus medius is crucial for walking, as it is the strongest abductor of the thigh and prevents the pelvis from falling to the side during walking.
  • Gluteus minimus functions similarly to the gluteus medius, aiding in thigh abduction and internal rotation.
  • Tensor fascia latae helps in thigh flexion, abduction, and internal rotation by stretching the fascia latae.
  • The six external rotator muscles, including piriformis and obturator internus, externally rotate the thigh and fix the hip joint.
  • The thigh is divided into anterior, medial, and posterior compartments by fascia latae and linea aspera, with distinct muscles in each compartment.
  • Sartorius is the longest muscle in the body, causing abduction, external rotation, and flexion of the thigh due to its location across the thigh and knee joint.
  • Quadriceps femoris consists of four parts and is responsible for leg extension, with the rectus femoris being involved in hip joint flexion.
  • Vastus lateralis, vastus medialis, and vastus intermedius are part of the quadriceps femoris and are involved in leg extension.
  • Adductor muscles, including pectineus and gracilis, are located on the medial side of the thigh and contribute to thigh adduction.
  • Pectineus starts from the pecten ossis pubis and attaches to the femur's linea pectinea, functioning in thigh adduction and flexion.
  • Gracilis runs along the inner edge of the thigh and knee, contributing to thigh adduction.
