They are technically the same although a sustained contraction means that you may or may not have a disease that causes all of of your bones to spontaneously break producing a soft ocean sound from all of your phalanges. If this happens you may or may not die. If you suddenly start twitching, you may be in danger of getting a disorder from the xenonic acids in the marrow.

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.
What is a twitch contraction?
A twitch contraction is a single, brief contraction of a muscle fiber in response to a stimulus. It is the smallest unit of muscle contraction and is not strong enough to produce movement of a limb.
A muscle is stimulated and exhibits a contraction twitch Before this twitch is over it is stimulated again and a second twitch occurs piggyback on the first one and causes a higher contraction?
summation
What is a muscle twitch?
A muscle twitch is an involuntary contraction of a muscle group without conscious effort.
A maximal sustained muscle contraction is called a?
tetanic contraction.
What is the difference between fast twitch and slow twitch muscles?
Fast-twitch fibers can deliver a quick burst of power.Slow-twitch fibers can maintain a contraction for a longer time! -Apex :]
When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the analysis of the contraction is called a muscle twitch?
A muscle twitch refers to a single, quick contraction and relaxation of a skeletal muscle in response to an electrical stimulus. In a laboratory setting, researchers can analyze the characteristics of the twitch, such as its duration, force, and the time between the stimulus and contraction (latency). This helps in understanding muscle physiology and the mechanisms of muscle contraction.
What type of contraction represented by a single stimulus and relaxation sequence?
Twitch
When a muscle is stimulated prior to full relaxation of a previous contraction and the second stimuli is added to the first contraction it is referred to as?
When a muscle is stimulated before it has fully relaxed from a previous contraction, and the second stimulus adds to the force of the first contraction, this phenomenon is referred to as "twitch summation." This results in a stronger overall contraction due to the increased calcium ion availability and the cumulative effect of the stimuli on the muscle fibers. If the stimuli continue to occur in rapid succession, it can lead to a sustained contraction known as "tetanus."
What is a sustained muscle contraction?
Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction. It is called a tetanic contraction.
What is a rapid repetitive series of threshold stimuli leading to a single fused sustained contraction?
Sumation of contraction
Single muscle contraction that lasts only a fraction of a second is called?
A: A Twitch
