AQA A Level Psychology Neurons and neurotransmission

Which of the following is not a neurotransmitter?

• Acetylcholine

• Serotonin

• Dopamine

• Thyroxine

In a neuron, what are the tiny sacs that hold neurotransmitters called?

• Dendrites

• Nodes of Ranvier

• Terminal buttons

• Synaptic vesicles

Which of the following is true?

• Excitation decreases the likelihood that a neuron will fire

• Inhibition decreases the negative charge of the postsynaptic neuron

• Excitation increases the likelihood that a neuron will fire

• Inhibition increases the likelihood that a neuron will fire

What is the gap called that separates each neuron from the next?

• Syntax

• Synthesis

• Synatus

• Synapse

Which of these statements about the firing of a neuron is false?

• When a neuron is activated by a stimulus, it becomes positively charged causing an action potential

• When a neuron is in a resting state it is positively charged

• When a neuron is in a resting state it is negatively charged

• The action potential creates an electrical signal that travels along the axon

Which of the following is not a type of neuron?

• Sensory

• Reflex

• Motor

• Relay

Which of the following is not part of the structure of a neuron?

• Node of Ranvier

• Basal ganglia

• Myelin sheath

• Terminal buttons

Which part of the neuron carries the electrical impulse away from the cell body?

• Axon

• Nucleus

• Soma

• Dendrite

Which of the following statements about neurotransmitters is false?

• Neurotransmitters are chemicals that diffuse across the synapse

• Neurotransmitters are produced by the endocrine system

• Each neurotransmitter has a unique structure that fits perfectly into a post synaptic receptor site

• Neurotransmitters can have either an excitatory or inhibitory effect

Which part of the neuron contains the nucleus?

• Axon

• Myelin sheath

• Cell body

• Dendrite
