What is the muscle the performs the largest quantity of work?
what is the largst muscle in the muscular system
What muscle causes a joint to straighten when it contracts?
The muscle that causes a joint to straighten when it contracts are the extensor muscles. These include the triceps that work with the biceps to extend the arm.
Muscle contracts to move?
the muscles and the bone work together and attached
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
What movement occurs when the subscapularis contracts concentrically?
When the subscapularis muscle contracts concentrically, it performs internal rotation of the shoulder joint. This movement involves rotating the arm inward toward the midline of the body.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
What type of muscle contraction occurs when the bicep performs flexion?
When the bicep performs flexion, a concentric contraction occurs. In this type of contraction, the muscle fibers shorten as they generate force, allowing the elbow to flex and bring the forearm closer to the upper arm. This action is primarily facilitated by the biceps brachii muscle, which contracts to lift the weight against gravity.
What does it mean for muscles to work opposing pairs?
the answer is when one muscle contracts the other relaxes
What kind of muscle causes a joint to straighten when it contracts?
The muscle that causes a joint to straighten when it contracts is called an extensor. Extensors work by increasing the angle between the bones at a joint, allowing for actions such as straightening the arm or leg. For example, the triceps muscle is an extensor that straightens the elbow joint when it contracts.
When a muscle contracts, it pulls with what force?
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
How does the heart work simple?
the heart is a muscle that expands and contracts or pumps blood throughout the body.
