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
What is smooth sustained contraction due to rapid stimuli?
Smooth sustained contraction due to rapid stimuli refers to a sustained muscle contraction that occurs in response to a series of quick, successive stimuli without a complete relaxation phase between them. This phenomenon, often seen in smooth muscle tissue, results in a prolonged state of contraction, allowing for functions such as vasoconstriction or peristalsis in the digestive tract. The rapid stimuli lead to an accumulation of calcium ions within the muscle cells, enhancing the contractile response. This type of contraction is essential for maintaining continuous muscle tone and function in various physiological processes.
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
