When a single neuron sends a strong enough impulse to a muscle that how many muscle fibers does it cause to contract?

This will depend upon the number of muscle fibers the nerve innervates. However, all fibers innervated by the nerve should contract in response to the neuronal impulse.

What cells have fibers that can contract and relax?
Muscle fibres are a type of cell. They are found in bundles in muscles, surrounded by connective tissue, neurones and capillaries. Muscle fibres are long, multinucleated cells with a high tensile strength.
Do skeletal muscle fibers contain sarcomeres whereas smooth muscle fibers do not?
true
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
Skeletal muscle fibers differ from typical cells in that these muscle fibers have many nuclei. The skeletal muscle store calcium ions in the sarcoplasmic reticulum.
Why are skeletal muscle fibers unusual?
The skeletal muscle, or striated muscle, is the muscle attached to the skeleton. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The contraction of skeletal muscle is under voluntary control.
Cardiac muscle fibers electrically connect to neighboring fibers by?
Gap Junctions
What kind of muscle makes your heart?
You call it as cardiac muscles. The muscle fibers contract rhythmically. The muscle fibers are attached to each other end to end. This facilitates the conduction of the impulse. The muscle fiber can be stimulated to give you contraction of the the same.
If enough muscle fibers contract to make the muscle as a whole shorten in length the muscle is said to exhibit contractions?
concentric
What is the function of the muscle fibers?
muscle fibers contract the muscles when stimulated.
What is muscle protein?
it is tiny muscle fibers that contract and expand the muscle
Dose a whole muscle contract in a all or none fashion?
No. Only enough muscle fibres are recruited to achieve the task at hand.
Which cells have long fibers that can contract and relax?
Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
Do all types of muscle fibers produce movement?
No, intrafusal fibers don't contract.
What is a motor unit is made up of?
Motor neurons and the muscle fibers they transmit signals toA motor unit is a collection of muscle fibers that contract as a single functional unit when stimulated by an impulse from a motor neuron. The actual size can vary greatly, from many large muscle fibers in the quadriceps muscle group per motor unit to just a few muscle fibers in the muscles of the fingers per motor unit.
Inability of muscle fibers to contract after a long period of contraction?
muscle fatigue
What is the role of slow muscle fibers and fast muscle fibers in the response of a muscle to different types of exercise?
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
Principle by which muscle fibers contract?
Sliding filament mechanism
Which kind of muscle fibers contract rapidly?
fast twitch
