1. The body has THREE kinds of neurons:

• connect sensory and motor neurons

• motor neurons

• pick up info and transmits to the brain

• Sensory neurons

• signals from brain to direct movement

• Interneurons

Reorder the chain of nerve impulses relay from the end of an axon tip (and its dendrite) :

• To the connecting neuron membrane of the next neuron in the chain.

• Neurotransmitters which signal 

• A gap called a synapse to “fire” chemicals to trigger/pass-along the impulse
