Unit 2 Terms- Neurons

Question 1

Which way does the action potential travel?

Answer 1

Dendrites to Terminals (ONLY THIS WAY)

Question 2

Explain how the process of a neuron firing is similar to toilet flushing

Answer 2

good job

Question 3

What is the process of neurons communicating

Answer 3

• Outside stimulation causes neuron to fire (another neuron, senses, etc)
• Action potential travels down the axon to the terminals
• Neurotransmitters release from the terminals and cross the synaptic gap
• bind to receptors of the receiving neuron

*Excess neurotransmitters are either broken down by enzymes, float away, or are absorbed back into the sending neuron by reuptake

*Excitatory arouse the body and inhibitory do the opposite
