What else can I help you with?
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.
When the muscle contracts what happens to the tendon and bone?
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
When a muscle contracts, what physiological process is occurring within the body?
When a muscle contracts, the physiological process occurring within the body is the shortening of muscle fibers, which results in the generation of force and movement.
When a muscle contracts and exerts force what is the energy used?
ATP - Adenosine triphosphate
What is the difference between passive and active tension in muscle contraction?
Passive tension is the force exerted on a muscle when it is stretched, while active tension is the force generated by the muscle when it contracts.
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
If a muscle contracts and its fibers shorten is the contraction isometric?
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
What is an example of and internal force?
An example of an internal force is the tension created within a muscle when it contracts to move a body part.
What happens when a muscle pulls a force on a bone?
skeletal muscles that are attached to ligaments that are attached to bone
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
When a muscle contracts?
shortens
What happens when a muscle contracts?
When a muscle contracts, it shortens in length, causing movement of the body part it is attached to. This contraction is triggered by signals from the nervous system, which stimulate the muscle fibers to slide past each other, generating force and tension.
