What are the two types of fibers that project from a neuron's cell body?
The two fibers that a neuron has are the nerve and the myelin fibers
Why is there less precise control over leg muscles over eye muscles?
many muscle fibers are controlled by a single motor neuron
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.
Fatty covering material of neuron fibers?
Yelin
A motor neuron transmits signals to?
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.
What is the difference between nerve and neuron?
A neuron is an individual cell in the PNS or CNS that can be excited and conduct impulses along its axon. A nerve is a bundle of multiple neuron fibers that each are carrying their own signals. They are protected by connective tissue. Eventually the neuron fibers diverge away from the nerve to reach their destination.
The sheath around some neuron fibers that aids in regeneration?
neurilemma
What part of the neuron would be responsible for notifing the brain that you hurt yourself?
Sensory nerve fibers carry message to brain. A part of neuron or or single neuron does not carry this message to the brain.
What motor neuron and all the muscle fibers it innervates called?
the motor unit
Through which part of the neuron does an impulse leave the cell?
Terminal end fibers
How many muscle fibers stimulate one somatic motor neuron?
150
