Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction.
It is called a tetanic contraction.

An example of partial but sustained contraction is?
A Muscle Tone .
An example of a partial but sustained contraction would be?
muscle tone
An example of a partial but sustained contraction would be what?
muscle tone
A maximal sustained muscle contraction is called a?
Tetanus
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
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
How does skeletal muscle stimulation produce a sustained contraction?
By stimulating alternating motor units at a time.
What would occur if the uptake of calcium ions was blocked in the sarcoplasmic reticulum?
Sustained muscle contraction.
The Ca2 that is required for sustained contraction of smooth muscle fibers comes mainly from the?
extracellular fluid surrounding the fibers
What is the difference between tonus and tetanus?
1. Even when a muscle appears to be at rest, a certain amount of sustained contraction is occurring in its fibers. This is called muscle tone. (Muscle tone is a response to nerve impulses that originate repeatedly from the spinal cord and stimulate a few muscle fibers.) A tetanic contraction is when a forceful sustained contraction lacks even partial relaxation.
