extensor digitorum
Which of these muscles is not responsible for flexion or extension of the arm?
The Triceps muscle
joints
Muscle tone
Flexor and extensor tendons connected to skeletal muscle
This muscle is called the extensor muscle. There are specific names for different joints.
latissimus dorsi
Since the mitochondria produces energy and the muscle cells are part of the mitochondria, they use the energy so they can move the joints.
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
skeletal muscle Joints
The over-extension of a muscle might feel like burning or pain in the muscle. After the exercise, the muscle can feel sore or even swollen.
Inn other words muscle flexing can be called muscle shortening and extension when muscle is elongating. For example when you bend you arm towards your shoulder your bicep muscle is shortening and you can feel a bump. When you extend your arm you can feel that the bump is stretching out and disappearing, that is muscle extension.
Smooth (organs)Cardiac (heart muscle)Skeletal (movement, support, strength)Muscle cells have a nucleus just like other cells. The basic units of a muscle cell are the actin and myosin filaments that slide past each other to allow flexion and extension of your joints.
Quadriceps muscle or thigh muscle.
Flexion and extension.
muscle
A muscle that, from origin to insertion, crosses two joints, and thus can produce an action at both joints. Example: the "hamstrings" (semimembranosis and semintendinosis) cross the hip joint and the knee joint and act on both joints (extend at hip, flex at knee).
