What is quadriceps?</h3>
Musculus quadriceps femoris means "four-headed muscle" in Latin. It is so named because it consists of four individual muscles. The rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius.
Of the four muscles, only the rectus femoris crosses both the hip and knee joints. Others cross only the knee joint. These muscles have different origins but share a common tendon of the quadriceps that inserts into the patella.
The function of the quadriceps is to straighten the leg at the knee and flex the thigh at the hip. The rectus femoris is a fusiform muscle that consists of two heads. It originates from two sites on the ilium.
Therefore, The quadriceps, commonly known as the quadriceps, is the strongest muscle in the human body. It is located in the anterior compartment of the thigh with the sartorius muscle.
