Unit 2 Part 1 Review
AP Psychology
1.
Draw, label and describe the functions of the parts of a neuron.
2.
Discuss the process of a message traveling within a neuron (be sure to mention action potential, resting
potential, depolarization, refractory period, threshold, excitatory, inhibitory).
3.
Discuss the process of neurotransmission – the message traveling between cells (be sure to mention:
synapse/synaptic cleft, terminal buttons, receptor sites, lock and key model)
4.
Understand and describe why within a neuron is electrical and between neurons is chemical.
5.
Discuss the All or None idea related to neurotransmission.
6.
Describe the differences between excitatory and inhibitory, and explain how neurons fire differently for a
stronger stimulus. Also mention whether or not the speed of transmission changes with the stimulus.
7.
Describe the functions and possible associated disorders related to the following neurotransmitters:
acetylcholine, dopamine, GABA, glutamate, norepinephrine, and serotonin.
8.
Describe the role of endorphins in the body.
9.
Define the differences between the central nervous system and the peripheral nervous system.
10. Define and understand the differences between sensory neurons, interneurons and motor neurons.
11. Differences between the peripheral nervous system – discuss the differences between the somatic and
autonomic nervous systems.
12. The autonomic nervous system is broken into two parts – sympathetic and parasympathetic. Discuss what
happens in each system. Also describe what happens in each part of the body: eyes, heart, stomach, pancreas,
liver, adrenal gland, kidney.
13. Describe how reflexes work in the body and why we have them. Give examples. (Also referred to as a simple
pain reflex.)
14. Describe a neural network. Discuss how the path between two pieces of information can become easily
connected to each other.
