Communication

Question 1

Axon

Answer 1

transfers electrical impulse from body to synapse

Question 1

Dendrite

Answer 1

receives electrical impulses on the receptor site.

Question 2

Axon terminal

Answer 2

release of messages

Question 3

Soma

Answer 3

cell body

Question 4

Myelin

Answer 4

cover on the axon and insulates electrical signals allowing quicker movement

Question 5

Neurotransmitters

Answer 5

chemicals that neurons use to communicate with each other
- messages are passed through the synaptic gap
- released through the axon terminal through to the synaptic gap then to the dendrite

Question 6

Electrochemical messaging

Answer 6

neurons passing messages
- inside the neuron the message is electrical
- outside the neuron the message is in chemical form

Question 7

Synaptic gap

Answer 7

the space between two neurons.

Question 8

What is a nerve?

Answer 8

a bundle of axons

Question 9

What is a neuron?

Answer 9

an individual nerve cell that the entire nervous system is made of

Question 10

Difference between excitatory and inhibitory

Answer 10

Excitatory = means post synaptic is more likely to fire
Inhibitory = means post synaptic is less likely to fire

Question 11

Electrochemical and neuron messaging

Answer 11

Neurons passing messages is an electrochemical message.
- inside the neuron the message is electrical (impulse
- outside the neuron the message is in chemical form (neurotransmitter)
