What voltage produced maximal contraction of the muscle?
The voltage that produces maximal contraction of a muscle is called the maximal stimulus voltage. This voltage is typically higher than the threshold voltage required to elicit a muscle contraction and ensures that all muscle fibers within a motor unit are stimulated to contract simultaneously, leading to a stronger contraction.
What is maximal speed?
Maximal strength is when your stamina improves in your muscle's.
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
The structures within the muscle fiber that shorten to cause skeletal muscle contraction are called myofibrils. Myofibrils are composed of repeating units called sarcomeres, which contain thick and thin filaments made of proteins (actin and myosin). When the muscle fiber is stimulated by a nerve impulse, the myosin heads interact with the actin filaments to generate the force required for muscle contraction.
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
What voltage produced maximal contraction of the muscle?

This voltage is typically higher than the threshold voltage required to elicit a muscle contraction and ensures that all muscle fibers within a motor unit are stimulated to contract simultaneously, leading to a stronger contraction.
What is a sustained muscle contraction?
Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction. It is called a tetanic contraction.
What is a sustained muscle contraction called?
unfused (incomplete) tetanus
Some muscle fibers always contracted?
Summation and/or tetanic contraction. Summation is increased muscle contraction until maximal sustained contraction is achieved. Tetanic contraction is sustained muscle contraction without relaxation. If you're inquiring for the Learning Objective Review in an anatomy and physiology course, the question refers to a condition in which some fibers are always contracted... so I'm not sure if they're looking for summation or tetanic contraction - but I think it would be tetanic contraction as summation is more the process leading up to the tetanic contraction...
A sustained muscle contraction due to a lack of relaxation between successive stimuli is called?
tetanus
An example of partial but sustained contraction is?
A Muscle Tone .
An example of a partial but sustained contraction would be what?
muscle tone
An example of a partial but sustained contraction would be?
muscle tone
What is muscle tetanus?
is produced by Clostridium tetani bacteria. Tetanus involves generalized rigidity and painful convulsive spasms of skeletal muscles, occurring 3 to 21 days after infection. The muscle stiffness usually involves the jaw (lockjaw) and neck muscles, and then becomes generalized.
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
What employs a parallel after discharge circuit to produce sustained muscle contraction?
a oscillating circuit
How does skeletal muscle stimulation produce a sustained contraction?
By stimulating alternating motor units at a time.
