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.
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.
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.
What muscle actions would be classified as isotonic contractions?
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
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.

What happens when the muscle contracts?

When one muscle contracts what happens to the opposing muscle?

What is it called when a Muscle contracts against a constant movable object?
an isometric contraction iso=same metric=length therefore the muscle maintains the same length as it contracts
What happens when an entire muscle contracts strongly and stays contracted?
when a muscle cramps
If one muscle contracts what happens to the other one?
relax
What happens to the muscle fibers in your biceps when you bend your arm?
it contracts
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.
What is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
When a muscle contrats what happens to its opposite muscle?
depends on which muscle but the opposite muscle sometimes contracts aswell to stabalize the joint some relaxes ...
What happens when a muscle contracts?
when the muscle shortens (contracts), the two bones come closer together, isometric contraction excepted.
