Psychology 202 Exam Test Questions
With All Verified Solutions.
Cerebral cortex - Answer -The intricate fabric of interconnected neural cells covering the cerebral
hemispheres; the body's ultimate control and information-processing center.
-thought & planning
-contains the frontal, parietal, temporal, and occipital lobe
Hypothalamus - Answer -A neural structure lying below the thalamus; it directs several maintenance
activities (eating, drinking, body temperature)
-Helps govern the endocrine system via the pituitary gland
-Linked to emotion and reward.
-Part of the limbic system
Amygdala - Answer two lima bean-sized neural clusters that are components of the limbic system and
are linked to emotion
Hippocampus - Answer -A neural center located in the limbic system that helps process explicit
memories for storage
-Easy way to recall: If you see a hippo walking into class you will surely remember that memory for
awhile
Thalamus - Answer -the brain's sensory switchboard, located on top of the brainstem
-directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum
and medulla
-part of the limbic system
-essentially the gateway to the cortext
Basal ganglia - Answer -a set of subcortical structures that directs intentional movements
-part of the limbic system
,Brain stem - Answer -Connection to spinal cord
-Filters information flow between peripheral nervous system and the rest of the brain.
Limbic system - Answer A doughnut-shaped system of neural structures at the border of the brainstem
and cerebral hemispheres
-associated with emotions such as fear and aggression and drives such as those for food and sex
-Includes the hippocampus, amygdala, hypothalamus, thalamus, pituitary gland, and basal ganglia
Pons - Answer -A brain structure that relays information from the cerebellum to the rest of the brain
-sleep, arousal, facial expressions
-connects the cerebellum to the rest of the brain
Meta-analysis - Answer -a procedure for statistically combining the results of many different research
studies
-larger view of replication
-example: math ability & gender
Occlusion - Answer -helps you detect depth
-whether or not objects are in front, behind, or obscuring other objects
D2 receptors - Answer -The dopamine receptors that the original antipsychotics bound to
-regulate self-control in frontal lobe
-Important point: might harm the individual's ability to make a good decision, perhaps to steal money
from a parent to be able to afford a drug again
3 types of neurons - Answer sensory, motor, interneurons
Myelin sheath - Answer -A layer of fatty tissue segmentally encasing the fibers of many neurons
(insulation)
,-enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the
next
Sensory neurons - Answer -neurons that carry incoming information from the sensory receptors to the
brain and spinal cord
-afferent
-incoming information to the CNS
Motor neurons - Answer -neurons that carry outgoing information from the brain and spinal cord to
the muscles and glands
-efferent
-outgoing information from CNS to muscles
Interneurons - Answer -Central nervous system neurons that internally communicate and intervene
between the sensory inputs and motor outputs
-Essentially connect sensory, motor, and other neurons
Main components of a Neuron - Answer -Cell body
-Dendrites
-Axon
Cell body - Answer -Largest part of a typical neuron
-contains the nucleus and much of the cytoplasm
-integrates information
Dendrites - Answer Branchlike parts of a neuron that are specialized to receive information
Axon - Answer -messages pass to other neurons or to muscles or glands
-transmits information
-contains axon terminal and synapse
, Axon terminal - Answer -The endpoint of a neuron where neurotransmitters are stored
-outgoing information
Synapse - Answer -the junction between the axon tip of the sending neuron and the dendrite or cell
body of the receiving neuron
-incoming/receiving
Glial cells - Answer -cells in the nervous system that support, nourish, and protect neurons
-formation of blood-barrier and myelin sheath
-supply nutrients to neurons
-support structure
Histology - Answer the study of the microscopic structure of tissues
EEG (electroencephalogram) - Answer -amplified recording of the waves of electrical activity that
sweep across the brain's surface
-waves are measured by electrodes placed on the scalp
Nervous system - Answer -the network of nerve cells and fibers that transmits nerve impulses between
parts of the body
Central Nervous System (CNS) - Answer consists of the brain and spinal cord
PET scan (positron emission tomography) - Answer -brain-imaging technique that reveals activity in
various parts of the brain, based on patterns of blood flow, oxygen use, and glucose consumption
Lesions - Answer removal or destruction of part of the brain
