CORRECT ANSWERS
GRADED A+ LATEST 100%
GUARANTEED PASS
resting potential - CORRECT ANSWER-the electrical charge difference between the inside and
outside of a neuron when it is not transmitting signals.
excitatory postsynaptic potential (EPSP) - CORRECT ANSWER-a graded depolarization of a
postsynaptic neuron's membrane, making it more likely to generate an action potential
inhibitory postsynaptic potential (IPSP) - CORRECT ANSWER-a graded hyperpolarization of a
postsynaptic neuron's membrane, making it less likely to generate an action potential
reflex arc - CORRECT ANSWER-the neural pathway that mediates a reflex action
temporal summation - CORRECT ANSWER-the process by which multiple EPSPs or IPSPs
occurring in rapid succession at the same synapse combine to influence a neuron's membrane
potential
synaptic delay - CORRECT ANSWER-the brief delay between the arrival of an action potential at
the presynaptic terminal and the initiation of a postsynaptic response
synaptic transmission - CORRECT ANSWER-the process by which neurons communicate with
each other at synapses using neurotransmitters
,synaptic vesicles - CORRECT ANSWER-small sacs within presynaptic terminals that store
neurotransmitters before their release
synaptic inhibition - CORRECT ANSWER-the process by which neurotransmitters cause
hyperpolarization of the postsynaptic membrane, decreasing the likelihood of an action
potential
autonomic nervous system - CORRECT ANSWER-portion of the nervous system that neurons
that control the body's organs, with the sympathetic nervous system preparing for vigorous
activity and the parasympathetic nervous system facilitating non-emergency responses
central nervous system (CNS) - CORRECT ANSWER-portion of the nervous system that includes
the brain and spinal cord, responsible for processing sensory information and initiating motor
responses
enteric nervous system - CORRECT ANSWER-portion of the nervous system controls the
digestive system's functions
forebrain - CORRECT ANSWER-the most anterior part of the brain, comprising the
telencephalon and diencephalon, involved in higher-order functions, such as thinking,
perception, and voluntary movement
hindbrain - CORRECT ANSWER-the posterior part of the brain, consisting of the medulla, pons,
and cerebellum, crucial for vital functions like breathing, heart rate regulation, and motor
coordination
peripheral nervous system (PNS) - CORRECT ANSWER-portion of the nervous system that
connects the CNS to the rest of the body, including the somatic nervous system and autonomic
nervous system
, somatic nervous system - CORRECT ANSWER-portion of the nervous system consisting of axons
conveying messages from the sense organs to the CNS and from the CNS to the muscles
sympathetic nervous system - CORRECT ANSWER-portion of the nervous system that prepares
the body for "fight or flight" responses, increasing heart rate and decreasing digestive activity
anterior commissure - CORRECT ANSWER-a bundle of axons connecting corresponding parts of
the two cerebral hemispheres
binding problem - CORRECT ANSWER-the theoretical challenge of understanding how different
brain areas coordinate to produce unified perceptions
cerebral cortex - CORRECT ANSWER-the largest part of the mammalian brain, responsible for
higher brain functions such as perception, cognition, and voluntary movement
lobes - CORRECT ANSWER-the four main regions of the cerebral cortex—occipital, parietal,
temporal, and frontal—that are associated with different functions
prefrontal cortex - CORRECT ANSWER-the anterior portion of the frontal lobe, responsible for
decision-making, planning, and aspects of memory and cognition
temporoparietal junction - CORRECT ANSWER-the area where the parietal lobe and temporal
lobe meet; it is important for attention, body awareness, and social cognition
visual cortex - CORRECT ANSWER-the area of the occipital lobe responsible for processing visual
information
Ablation - CORRECT ANSWER-the surgical removal of a brain area, typically performed with a
surgical knife, to produce localized brain damage in laboratory animals for research purposes
