Question 1

What are synapses?

Answer 1

They are the gaps between adjacent neurons

Question 2

What is the first step in how impulses are transferred between neurons?

Answer 2

A nerve impulse reaches the synapse through the sensory neuron

Question 3

What is the second step in how impulses are transferred between neurons?

Answer 3

The impulse triggers the release of chemicals, called neurotransmitters, into the synapse

Question 4

What is the third step in how impulses are transferred between neurons?

Answer 4

Neurotransmitters diffuse across the synapse and bind with receptor molecules on the membrane of a motor neuron

Question 5

What is the fourth step in how impulses are transferred between neurons?

Answer 5

A nerve impulse is sent through the motor neuron

Question 6

What do the receptor molecules bind with?

Answer 6
