Biological Psychology Exam Questions with 100%
Verified Correct Answers
1. biological psychology - Correct Answer Definition: a branch of psychology concerned with the links
between biology and behavior
Application: When something was wrong with Tommy's left hemispherical lobe, they immediately
began to search for biological psychologists.
2. neuron - Correct Answer Definition: a nerve cell; the basic building block of the nervous system
Application: Neurons receive and send messages.
3. dendrites - Correct Answer Definition: the bushy, branching extensions of a neuron that receive
messages and conduct impulses toward the cell
Application: The way the messages in my brain are transferred are through the dendrites.
4. axon - Correct Answer Definition: the extension of a neuron, ending in branching terminal fibers,
through which messages pass to other neurons or to muscles or glands
Application: Messages are sent down my neuron's axon to go to the synaptic vesicles.
5. myelin sheath - Correct Answer Definition: a layer of fatty tissue segmentally encasing the fibers of
many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops
from one node to the next
Application: The more one practices the more their axon is myelinated and the better they are at the
thing they are practicing for.
6. endorphins - Correct Answer Defintion: "morphine within"- natural, opiatelike neurotransmitters
linked to pain control and to pleasure
Application: People who get a "runner's high" are receiving lots of endorphins.
7. refractory period - Correct Answer Defintion: a resting period after orgasm, during which a man
cannot achieve another orgasm
Application: One's organs need to reset.
8. threshold - Correct Answer Definition: the level of stimulation required to trigger a neural impulse
, Application: When a neuron reaches threshold the message is sent down the axon to eventually
continue on to another neuron.
9. all-or-none response - Correct Answer Definition: when a neuron will either reach threshold or
withhold the information
Application: If the message is important enough to send it would be considered "all".
10. synapse - Correct Answer Definition: the junction between the axon tip of the sending neuron
and the dendrite or cell body of the receiving neuron
Application: The synapse continues on the message to the next neuron's receptor site.
11. neurotransmitters - Correct Answer Definition: chemical messengers that cross the synaptic gaps
between neurons. When released by the sending neuron, neurotransmitters travel across the
synapse and bind to receptor site son the receiving neuron, thereby influencing whether that neuron
will generate a neural impulse
Application: The messages being sent between the neurons are the neurotransmitters.
12. reuptake - Correct Answer Definition: a neurotransmitter's reabsorption by the sending neuron
Application: When the neuron contains the other neurons message.
13. action potential - Correct Answer Definition: a neural impulse; a brief electrical charge that
travels down an axon
Application: An impulse made by the neuron.
14. agonist - Correct Answer Defintion: Mimics effects of a neurotransmitter or may block
neurotransmitter's repute.
Application: Heroin, cocaine and meth are all agonists.
15. antagonist - Correct Answer Defintion: block a neurotransmitter's function
Application: Botox is an antagonist.
16. nervous system - Correct Answer Definition: the body's speedy, electrochemical communication
network, consisting of all the nerve cells of the peripheral and central nervous systems
Application: The nervous system allows all of the cells nerve cells to communicate.
