APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The quadriceps femoris is a group of four muscles: vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris. This group is the primary extensor of the knee. The quadriceps femoris connects to the patella via the quadriceps tendon, which then extends to insert at the tuberosity of the tibia.

Detailed explanation-2: -The muscles that make up the anterior compartment of the thigh are sartorius and the quadriceps femoris muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). Psoas major and iliacus muscles also pass into the upper aspect of the anterior compartment.

Detailed explanation-3: -The muscles in the thighs are divided into three main groups: the hamstring muscles, the quadriceps muscles, and the adductor muscles. The hamstring muscles are present in the back or the posterior compartment of the thigh. The quadriceps are part of the front of the anterior compartment of the thigh.
