What else can I help you with?
An example of partial but sustained contraction is?
A Muscle Tone .
A maximal sustained muscle contraction is called a?
tetanic contraction.
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 a sustained muscle contraction called?
unfused (incomplete) tetanus
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.
A sustained muscle contraction due to a lack of relaxation between successive stimuli is called?
tetanus
Skeletal muscle twitch differs from a tetanic contraction in that?
Skeletal muscle twitch is a single, brief contraction and relaxation cycle, whereas a tetanic contraction involves sustained, rapid repeated contractions without relaxation in between. Tetanic contractions occur when the muscle is stimulated at a high frequency, leading to a fused contraction.
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...
The Ca2 that is required for sustained contraction of smooth muscle fibers comes mainly from the?
extracellular fluid surrounding the fibers
What summation occurs when a second contraction is added to the irst before complete relaxation?
When a second contraction occurs before complete relaxation of the first, it leads to a phenomenon known as "tetanus." This summation of muscle contractions increases the overall force produced by the muscle, as the second contraction adds to the tension generated by the first. As a result, the muscle remains in a more sustained and powerful state of contraction, rather than returning to its resting state. This is critical for activities requiring sustained muscle force, such as lifting or maintaining posture.
