The quadriceps. They are made of four individual muscles; rectus femoris, vastus intermedius, vastus lateralis, and vastus medialis.
The tensor fascia latae also plays a small role in knee extension.
Four Quadriceps - Rectus Femoris, Vastus Lateralis, Vastus Medialias, Vastus Intermedius
vastus lateralis, vastus medialis and vastus intermedius. The forht muscle of the quad (rectus femoralis) works in close association with the hip than with the knee.
hamstring group is the primary muscle group for flexing the knee
It is called the Sartorius muscle located in the thigh. Here is the long definition. Assists in flexing, abduction and later rotation of the hip and flexing of the knee.
The muscle that originates from the anterior inferior iliac spine of the hip and inserts onto the proximal end of the tibia is the sartorius muscle. This muscle is the longest muscle in the body and is responsible for flexing, abducting, and laterally rotating the hip joint, as well as flexing the knee joint.
the hamstring is used for flexing the knee
Paralysis of the quadriceps femoris muscle would make an individual unable to flex the thigh. This muscle is responsible for extending the knee and flexing the thigh at the hip joint.
The two anterior aspects of the upper thigh are the quadriceps femoris muscle group and the sartorius muscle. The quadriceps femoris group is a large muscle that covers the front of the thigh and is responsible for extending the knee joint. The sartorius muscle is the longest muscle in the body and helps with flexing the hip and knee joints and rotating the thigh.
The opposite job of the quadriceps is primarily performed by the hamstrings. While the quadriceps are responsible for extending the knee and are involved in activities like kicking and squatting, the hamstrings are responsible for flexing the knee and extending the hip. These two muscle groups work antagonistically to facilitate movement and maintain balance in the legs.
Cats do not have a psoas minor muscle. They have a psoas major muscle, which is responsible for flexing the hip joint.
The flexor digitorum superficialis muscle in the forearm is roughly the size of your fist. It is responsible for flexing the fingers.
Biceps are a muscle, not a tissue. The biceps brachii muscle is located in the upper arm and is responsible for flexing the elbow and rotating the forearm.
The sartorius muscle is primarily responsible for crossing one leg over the other while sitting. This long, thin muscle runs from the outer hip to the inner knee and is involved in flexing and rotating the hip and knee joints.
The rectus abdominis muscle is responsible for flexing the spine and helping to maintain posture in the human body.
