One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.

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.
A motor neuron and the muscle fibers it controls are called?
the motor unit
The combination of a neuron and the muscle fibers it associates with is called?
Motor unit = the single motor neuron and the multiple muscle fibers that it innervates.
What motor neuron and all the muscle fibers it innervates called?
the motor unit
A single neuron and all the muscle fibers it stimulates comprise a?
This is called a motor unit.
Define motor unit?
a motor neuron together with the muscle fibers (cell) it stimulates.
What consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates?
motor unit
What does powerlifting do?
Diminishes hormonal adaptations of muscle fibers and does not allow sufficient motor unit activation.
What is difference between single motor unit and multi motor unit?
There is no 'multi motor unit' to be different from a single motor unit!A single motor unit is all the muscle fibers controlled by a single motor neuron.Multiple motor unit summation is when a smooth and steady increase in muscle tension is produced by increasing the number of active single motor units.Notice that what's being described is not something having to do with a some non-existent thing called a 'multi motor unit', but rather is a summation of many active singlemotor units.
What is the difference between fast twitch and slow twitch muscle fibers?
Fast twitch muscle fibers are Type II muscle fibers. These muscle fibers have high explosive power and are anaerobic. They have a fast contractile speed and can reach peak tension in 50ms. They have a high glycolytic capacity and have low to moderate resistance to fatigue. Their motor unit strength is high.Slow twitch muscle fibers are Type I muscle fibers. These muscle fibers have steady power and are aerobic. The have a slow contractile speed and needs 110ms to reach peak tension. They have a low glycolytic capacity and a high resistance to fatigue. Their motor unit strength is low.
What part of nervous system controls voluntary movements thoughts and registration of incoming information?
The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.
Smallest contractile unit individual muscle fibers?
