Response of a motor unit to a single action potential of it motor neuron is called?
muscle twitch
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 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 the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
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 muscle responsible for action in a single direction is called?
it's called a prime mover
According to the all or none principle what would happen if a cell were depolarized twice the normal amount needed to produce an action potential?
If a cell were depolarized twice the normal amount needed to produce an action potential, it would still only produce a single action potential. The all-or-none principle states that once the threshold for an action potential is reached, the neuron will fire with a fixed amplitude and duration regardless of the strength of the stimulus.
What was the model name of the single action revolver produced by ruger in 30 carbine?
Blackhawk.
Skeletal muscle fiber is controlled by a motor neuron at a single?
Each muscle cell is only innervated by a single motor neuron, but each motor neuron innervates any number of muscle cells. When an action potential travels down the axon of an alpha motor neuron, it will depolarize several muscle cells at the same time, a phenomenon known as summation.
