Vastus Medialis is a muscle located on the front of the thigh and is part of the quadriceps group, which is crucial for knee extension and stabilizing the patella during walking, running, and squatting. It attaches along the length of the femur and inserts into the patella and tibial tuberosity via the patellar ligament, playing a vital role in leg extension.
The name "Vastus Medialis" comes from Latin, where "vastus" means "large" or "great," and "medialis" indicates its position toward the midline of the body.
If the Vastus Medialis were absent or damaged, the body would struggle with or be unable to extend the knee properly, compromising movements like walking, running, standing from a sitting position, and maintaining balance, especially in the seated or crouched positions.
