What consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates?
motor unit
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.
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 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
What motor neuron and all the muscle fibers it innervates called?
the motor unit
What is A neuron that can cause muscles to contract?
Efferent motor neurons stimulate muscle contractions.
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
Define motor unit?
a motor neuron together with the muscle fibers (cell) it stimulates.
A motor neuron and the muscle fibers it controls are called?
the motor unit
