Biopsych: Neurons and synapse transmission

Question 1

Sensory neurons

Answer 1

Carry messages from the peripheral nervous system to the brain and spinal cord (CNS)
Example: smelling food or putting your hand on something hot

Question 2

Motor neurons

Answer 2

Carry messages away from the brain and spinal cord (CNS) to muscles and organs

Question 3

Connector/relay neurons

Answer 3

Only found in the visual system, brain and spinal cord
Receive messages from sensory neurons
Pass messages onto motor neurons

Question 4

Re-uptake

Answer 4

Leftover neurotransmitters are taken back into the original cell and recycled

Question 5

Enzymes

Answer 5

Break down any leftover neurotransmitters

Question 6

Excitation

Answer 6

When the neurotransmitter increases the positive charge, which increases the likelihood that the neuron will fire and electrical impulse
Makes the next neuron carry the impulse

Question 7

Inhibition

Answer 7

When the neurotranmitter increases the negative charge, decreasing the likelihood that the neuron will fire an electrical impulse
Stops the next neuron from carrying the impulse
