Q

The long cable reaching out towards the next output to the brain is the ____ .

25
What is the means by which the neuron communicates to the next neuron in line?
the axon
26
What reaches out to the dendritic spine of the next neuron?
axon terminals
27
What cell is in a supporting role in getting neurons to work?
glial cells
28
Where does excitation start?
dendritic end
29
What is the standard base function of neurons?

30
Hallmark of the nervous system?
