Neuropsychology WGU D574 Exam
Questions With Correct Answers
Mind-brain problem |
Question of how/why certain types of brain activity are conscious.
| | | | | | | | |
Monism
Idea that the universe consists of one type of being; different ways of
| | | | | | | | | | | | |
describing the same thing.
| | |
Dualism
Idea that mind and body are different kinds of substance that exist
| | | | | | | | | | | |
independently.
Perception
Occurs in the brain; for example, something touching the hand sends a
| | | | | | | | | | | |
message to the brain.
| | |
,Physiological explanation |
Relates behavior to activity of brain/organs, such as chemical reactions
| | | | | | | | | |
that enable hormones to influence the brain.
| | | | | |
Ontogenetic explanation |
Describes how behavior develops, examining differences between males
| | | | | | |
and females at different ages.
| | | | |
Evolutionary explanation |
Explains structure/behavior based on evolutionary history, examining
| | | | | | |
behavioral similarities among related species.
| | | |
Functional explanation |
Explains why a structure/behavior evolved as it did, such as why certain
| | | | | | | | | | | |
traits were favored by natural selection.
| | | | |
Genetic drift |
,Gene spread by accident due to a dominant male with many offspring
| | | | | | | | | | | |
spreading the gene, both positive and negative.
| | | | | |
Ethical issues of research with laboratory animals
| | | | | |
Many mechanisms of behaviors are similar across species, making it
| | | | | | | | | |
easier to study non-humans.
| | |
Neurons
Cells that receive information and transmit it to other cells
| | | | | | | | |
Motor neuron |
receives excitation through dendrites and conducts impulse along axon
| | | | | | | | |
to muscle.
|
Sensory neuron |
Very sensitive at one end to particular stimuli.
| | | | | | |
, Soma/Cell body |
Contains nucleus, ribosomes, mitochondria, and is covered with
| | | | | | | |
synapse receptors. |
Intrinsic neuron |
Axons and dendrites are confinterm-18ed within a structure.
| | | | | | |
Glia
Type of cell that doesn't conduct impulses over long distances.
| | | | | | | | |
Astrocytes
Star-shaped glial cells that synchronize the activity of axons by wrap
| | | | | | | | | | |
around dendrites|
Tripartite synapse |
Tip of axon releases chemicals causing nearby astrocytes to release their
| | | | | | | | | |
own chemicals, modulating the message to the next neuron.
