What else can I help you with?
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 is a sudden intense involuntary muscle contraction?
A spasm A cramp A twitch A tick An epileptic fit
A twitch is in response to a single action potential?
Generally not as there are many parallel fibres that are part of the same circuit and some sort of coordination between the fibres are needed before a muscle twitch can be detected. This is either temporal or spatial summation.
What is a brief contraction of all muscle fibers in a motor unit in a response to a single action potientia lmoving down the somatic motor neuron is known as what?
A brief contraction of all muscle fibers in a motor unit in response to a single action potential traveling down the somatic motor neuron is known as a muscle twitch. This twitch consists of three phases: the latent period, contraction phase, and relaxation phase. It represents the basic unit of muscle contraction and is essential for understanding muscle function and physiology.
The response of a motor unit to a single action potential of its motor neuron is called?
The response of a motor unit to a single action potential of its motor neuron is called a muscle twitch. This involves the contraction of all the muscle fibers within the motor unit in response to the stimulation from the motor neuron.
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.
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 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
Single muscle contraction that lasts only a fraction of a second is called?
A: A Twitch
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 is a sudden intense involuntary muscle contraction?
A spasm A cramp A twitch A tick An epileptic fit
What is a contractile response of a single muscle fiber to a single muscle impulse called?
The contractile response of a single muscle fiber to a single muscle impulse is called a "twitch." A twitch consists of a brief contraction followed by relaxation, and it can be divided into three phases: the latent period, contraction phase, and relaxation phase. The characteristics of a twitch, such as its duration and force, can vary depending on the type of muscle fiber involved.
What is a twitch?
a twitch is a single stimulus-contraction-relax action sequence in a muscle fiber. They can vary in duration depending on the type of muscle, it's location, internal and external enviromental conditions and other factors.
A twitch is in response to a single action potential?
Generally not as there are many parallel fibres that are part of the same circuit and some sort of coordination between the fibres are needed before a muscle twitch can be detected. This is either temporal or spatial summation.
