What else can I help you with?
When a muscle is stimulated repeatedly at a high rate the amount of tension gradually increase to a steady maximum tension is?
complete tetanus
When a muscle is stimulated repeatedly at a high rate the amount of tension gradually increases to a steady maximum tension is called?
complete tetanus
What is the tension of muscle fibers called?
The tension of muscle fibers is called muscle tension. It refers to the force generated by a muscle when it contracts. Muscle tension is necessary for movement, posture, and stabilization of the body.
Peak tension production occurs when all motor units in the muscle contract in a state of?
Complete tetanus
Why does a muscle that has been overstretched produce less tension?
A muscle that has been overstretched produces less tension because its filaments (actin and myosin) are no longer optimally aligned for contraction. This misalignment reduces the number of cross-bridges that can form between the filaments, leading to decreased force generation. Additionally, overstretching can also impair the muscle's elastic properties and overall functional capacity. As a result, the muscle becomes less efficient in generating tension during contraction.
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 does a muscle relaxant do to help alleviate muscle tension or spasms?
A muscle relaxant works by targeting the nervous system to reduce muscle contractions, helping to alleviate muscle tension or spasms.
What do you call the natural tension in the fibers of a muscle?
muscle tone
What is resting tension in a skeletal muscle called?
muscle tone
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
What are muscle spindles sensitive to?
tension
How do muscle relaxants work to alleviate muscle tension and spasms?
Muscle relaxants work by targeting the central nervous system to reduce muscle contractions and increase blood flow to the affected area, which helps alleviate muscle tension and spasms.
