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 :]
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 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.
A single muscle contraction that lasts only a fraction of a second is called a?
A single contraction that lasts only a fraction of a second is called a muscle twitch. Its when the muscle seizes up for a quick pulse then relaxes.
What are the three phases of a muscle twitch?
Tetinus, Complete tetinus, and absolute summation
