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
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 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
How do bones and muscles work to have movement?
The neuromuscular junction. A chemical called neurotransmitter is released from a neuron to stimulate the muscle fibers to contract.
How many muscle fibers stimulate one somatic motor neuron?
150
A single neuron and all the muscle fibers it stimulates comprise a?
This is called a motor unit.
The motor neuron and the muscle fiber it controls constitute a what?
Motor Unit :)
Define motor unit?
a motor neuron together with the muscle fibers (cell) it stimulates.
What is the job of his motor neurons?
controls musclesRelay messages from the Brain in the CNS down through the Spinal Cord and into the PNS, from there the motor neuron synapses on muscle fibers. i.e. knee jerk reflex & the neuromuscular junction.
