Define motor unit?

A motor unit consists of a motor neuron and all the muscle fibers it innervates. When the motor neuron fires, all the muscle fibers in the motor unit contract simultaneously. This coordinated activation allows for precise control of muscle force and movement.


What motor neuron and all the muscle fibers it innervates called?

the motor unit


The combination of a neuron and the muscle fibers it associates with is called?

The combination of a neuron and the muscle fibers it associates with is called a motor unit. Motor units work together to produce movement by having the neuron stimulate the muscle fibers it innervates to contract.


What is the difference between a motor unit and a motor neuron in the context of muscle movement?

A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.


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.


What consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates?

A motor unit consists of a somatic motor neuron and all the skeletal muscle fibers it innervates. When the motor neuron fires an action potential, all the muscle fibers in its motor unit contract simultaneously. Motor units vary in size depending on the precision of movement required, with smaller units needed for fine control and larger units for more powerful movements.


A motor neuron transmits signals to?

Muscle fibers


Once a motor neuron has fired all the muscle fibers in a muscle contract?

False


Once a motor neuron has fired all the muscle fibers in a muscle contract.?

False


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

When a single neuron sends a strong enough impulse to a muscle, it can cause multiple muscle fibers within that muscle to contract. The specific number of muscle fibers that contract will depend on factors like the size of the motor unit and the intensity of the signal from the neuron.


What refers to one neuron and all skeletal muscle cells it stimulates?

Motor unit


What is a motor neuron attached to?
