The muscle group found on the anterior part of the thigh is known as the quadriceps femoris, commonly referred to as the quadriceps or quads. This group consists of four muscles:
- Rectus Femoris: This muscle runs straight down the thigh and is responsible for flexing the hip and extending the knee.
- Vastus Lateralis: Located on the outer side of the thigh, this muscle helps in extending the knee.
- Vastus Medialis: Found on the inner part of the thigh, this muscle also aids in knee extension and stabilizes the kneecap.
- Vastus Intermedius: Situated between the vastus lateralis and vastus medialis, this muscle lies deep within the thigh and assists in knee extension.
Together, these muscles play a crucial role in activities such as walking, running, jumping, and squatting. They are essential for maintaining stability and strength in the lower body.
