Categorize the muscles that move the thigh, indicating whether each is found on the anterior, posterior, or medial group of the muscles.

The muscles that move the thigh are categorized into three groups: anterior, posterior, and medial.

1. Anterior Group: These muscles are located at the front of the thigh. They are primarily responsible for hip flexion and knee extension. The main muscles in this group include:

   • Quadriceps Femoris: This is the largest muscle group in the body and includes four muscles - the Rectus Femoris, Vastus Lateralis, Vastus Medialis, and Vastus Intermedius.
   • Sartorius: This is the longest muscle in the human body, running diagonally across the thigh.

2. Posterior Group: These muscles are located at the back of the thigh. They are primarily responsible for hip extension and knee flexion. The main muscles in this group include:

   • Hamstrings: This group includes three muscles - the Biceps Femoris, Semitendinosus, and Semimembranosus.
   • Gluteus Maximus: This is the largest muscle in the body, responsible for hip extension.

3. Medial Group: These muscles are located on the inner side of the thigh. They are primarily responsible for hip adduction. The main muscles in this group include:

   • Adductor Magnus
   • Adductor Longus
   • Adductor Brevis
   • Gracilis
   • Pectineus

Each of these muscles plays a crucial role in movements such as walking, running, jumping, and squatting.
