The nervous system is composed of what two main classes of cells? 
What are they? - Answer -Neurons and glial cells 
-- neurons = the basic signaling units that transmit information through 
the nervous system 
-- glial cells = non neural cells that provide structural support and 
electrical insulation to neurons. Glia are involved in metabolic functions, 
repair and protection of neurons, and...

What is the role of the axon hillock in neural signaling? 
 The axon hillock integrates incoming signals and determines whether to initiate an action 
potential. 
 
How does myelination affect the speed of action potential propagation along an axon? 
 Myelination increases the speed of action potential conduction by enabling saltatory 
conduction, where the signal jumps between nodes of Ranvier.
