18. _______are highly specialized nerve cells that generate and conduct nerve impulses.
23. Neurons categorized as________neurons have several dendrites and a single prominent axon.
25. In the peripheral nervous system, Schwann cells are neuroglia cells that_______neuronal function by increasing the speed of impulse propagation.
26. The cell body is like a_______for the neuron.
27. When a neuron is sufficiently stimulated, it generates an action________that propagates down the axon towards the synapse.
28. If enough neurotransmitters are released at the synapse to_________the next neuron.
30. The main part of the cell, the part that carries on the_________functions, is the cell body.
