Quadriceps=4 heads
Femoris= Upper leg
Quadricepts femoris= 4 muscles of the upper leg.
A four head muscle in the leg/articulates with femoris bone Quadriceps femoris
It is connected to the tendon of the quadriceps femoris muscle.
The three muscles that aid on knee flexion are the semitendiosus, semimembranosus, and the biceps femoris. None of these muscles are considered the prime mover because they all cross two joints. Therefore all three of the muscles are considered to be synergist.
The muscle of the thigh are classified into three groups, anterior group, posterior group, and interior or adductors group. There are four muscle on the anterior group - quadriceps femoris- and their function is to extend the knee or extend the thigh depend on what part of the muscle don't move. Those muscle are the rectus femorarlis, vastu intermedius, vastu medialis, and vastus lateralis. The muscle that flex the knee are located on the back of the thigh and form the posterior group. They are the biceps femoris, semitendinousus, and the semimembranosus, better known as Hamstring.

The deep head of the quadriceps, known as the vastus intermedius, is the smallest of the four quadriceps muscles. It originates from the anterior and lateral surfaces of the femur and lies beneath the rectus femoris. The vastus intermedius contributes to the quadriceps tendon, which ultimately attaches to the patella and plays a crucial role in knee extension.
The quadriceps are a group of muscles on the front of your thighs., There are four distinct muscles that make up the quadriceps muscles.These muscles are called the vastus intermedius, the vastus medialis, the vastus lateralis, and the rectus femoris. The quadriceps are also known simply as the quads.The group inserts on the tibial tuberosity (a knot below the patella).Since the quadriceps extend over the kneecap (patella), they also help to keep your kneecap in its proper position in a groove in the end of your thigh bone.

Repeated blows to the quadriceps can lead to the formation of calcified tissue within the muscle, a condition known as myositis ossificans. This can cause pain, decreased range of motion, and inflammation in the affected muscle. Treatment may include physical therapy, anti-inflammatory medications, and in severe cases, surgery to remove the calcified tissue.
The patellar reflex, also known as the knee-jerk reflex, doesn't occur when your leg is straight because the muscle involved in the reflex, the quadriceps, is relaxed when the leg is fully extended. The reflex response occurs when the muscle is slightly stretched, triggering a signal to the spinal cord that leads to the reflexive contraction of the quadriceps.
The quadriceps muscles, located on the front of the thigh, are considered the strongest muscles in the lower body. They are responsible for extending the knee and are essential for movements like running, jumping, and squatting.
The patella, also known as the kneecap, is a small, flat bone that sits at the front of the knee joint. Its primary function is to protect the knee joint and provide leverage to the thigh muscles when bending or straightening the leg. The tibia, or shinbone, is the larger of the two lower leg bones and plays a crucial role in weight-bearing and supporting the body's movement.
