Neurons and Glia Flashcards
Are motor neurons myelinated or unmyelinated?
Myelinated
Which kind of neurons are unipolar?
Sensory Neurons
What does it mean for a neuron to be unipolar?
Means there are afferent and efferent branches
Where do Sensory neurons originate?
In the PNS
Where is the motor neuron soma?
In the CNS
Where does the axon of the motor neuron extend to?
Out past the PNS
How many axons are in a motor neuron?
A single axon
Incoming information in a sensory neuron goes toward what?
The CNS
Where is the soma of a sensory neuron?
In the Dorsal Root Ganglion (DRG)
Where is the ganglia of sensory neurons found?
In the Soma outside of the CNS
What is the function of interneurons?
Modulates responses in the brain between stimulus (sensory) and response (motor)
True or False: Interneurons are a single axon?
True
Where are Interneurons confined to?
