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.
Which body structure causes you to smile?
The zygomaticus major muscle is the primary muscle responsible for facial expressions such as smiling. When this muscle contracts, it pulls the corners of the mouth upward, creating the smile.
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 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.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
What happens when a muscle pulls a force on a bone?
skeletal muscles that are attached to ligaments that are attached to bone
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 the muscle contracts it pulls on and moves that bone at the joint?
ligament
What are thick bands that pull on bone as muscle contracts?
Thick bands that pull on bone as muscles contract are known as tendons. Tendons are strong, fibrous connective tissues that connect muscles to bones, allowing for the transfer of force generated by muscle contractions to facilitate movement. When a muscle contracts, it shortens and pulls on the tendon, which in turn pulls on the bone, resulting in joint movement.
When a skeletal muscle contracts a protein called a myosin hooks onto pulls against a partner protein called?
When a skeletal muscle contracts, a protein called a myosin hooks onto and pulls against a "partner" protein calledA. actin.B. a sarcoplasm.C.myofibril.D. a sarcomere.the answer is A actin
Where would you find your corrugator?
foreheadThe corrugator is the muscle that contracts the forehead into wrinkles and pulls the eyebrows together.
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 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.
Why does it hurt when I flex my bicep?
When you flex your bicep, the muscle contracts and pulls on the tendons that attach it to your bones. If there is inflammation or strain in the muscle or tendon, it can cause pain when you flex your bicep.
When a muscle contracts and exerts force what is the energy used?
ATP - Adenosine triphosphate
How can tendons pull bone?
on one end of a tendon comes from the muscles while the other hand is attached to a bone,then it pulls
Which body structure causes you to smile?
The zygomaticus major muscle is the primary muscle responsible for facial expressions such as smiling. When this muscle contracts, it pulls the corners of the mouth upward, creating the smile.
