QUESTIONS AND VERIFIED
CORRECT ANSWERS
GRADED A+ LATEST 100%
GUARANTEED PASS
behavioral neuroscience - CORRECT ANSWER-the study of the physiological, evolutionary, and
developmental mechanisms of behavior and experience, emphasizing the relationship between
biology and psychology
biological psychology - CORRECT ANSWER-also known as biopsychology, psychobiology, or
physiological psychology, this branch of psychology focuses on understanding behavior through
physiological, evolutionary, and developmental mechanisms
consciousness - CORRECT ANSWER-the state or quality of awareness, subjectivity, and
experience, particularly in the context of the mind-body problem and its relationship to brain
activity
evolutionary explanation - CORRECT ANSWER-the description of the evolutionary history of a
structure or behavior, highlighting modifications from ancestral species and adaptive
advantages
functional explanation - CORRECT ANSWER-the description of why a structure or behavior
evolved as it did, identifying the adaptive benefits conferred by certain traits
ontogenetic explanation - CORRECT ANSWER-the description of the developmental processes
underlying a behavior or trait, often involving genetic and environmental influences during an
organism's lifespan
,physiological explanation - CORRECT ANSWER-the description of the relationship between a
behavior and the activity of the brain and other bodily organs, focusing on the biological
mechanisms underlying behavior
neuroethics - CORRECT ANSWER-The study of ethical issues arising from research in
neuroscience and related fields, including concerns about animal research and human
experimentation
three R's - CORRECT ANSWER-reduction, replacement, and refinement; legal standards for
animal research aimed at reducing the number of animals used, finding alternatives to animal
models when possible, and refining procedures to minimize pain and distress
astrocytes - CORRECT ANSWER-star-shaped glial cells that wrap around dendrites, synchronize
closely related neurons, and regulate blood flow in active brain areas
axon - CORRECT ANSWER-a thin fiber of constant diameter that conveys impulses from one
neuron to another
dendrites - CORRECT ANSWER-branching fibers that receive information from other neurons
and contain synaptic receptors
glia - CORRECT ANSWER-non-neuronal cells that support and protect neurons, including
astrocytes, microglia, oligodendrocytes, and Schwann cells
mitochondria - CORRECT ANSWER-organelles responsible for generating energy (ATP) in cells,
which is crucial for brain function, cognition, and mental health
myelin sheath - CORRECT ANSWER-insulating material that surrounds and protects certain
vertebrate axons, improving the speed of nerve impulses
, neurons - CORRECT ANSWER-specialized cells responsible for receiving, processing, and
transmitting information in the nervous system
soma - CORRECT ANSWER-the cell body of a neuron containing the nucleus, ribosomes, and
mitochondria
synapse - CORRECT ANSWER-junction between two neurons where chemical signals are
transmitted from one neuron to another
action potential - CORRECT ANSWER-messages sent by axons, characterized by depolarization
of the neuron membrane
all-or-none law - CORRECT ANSWER-the principle stating that all action potentials, once
initiated, are approximately equal in amplitude and velocity, regardless of the intensity of the
stimulus
depolarization - CORRECT ANSWER-reduction of the difference in electrical charge between the
inside and outside of a neuron, leading to the initiation of an action potential
hyperpolarization - CORRECT ANSWER-increased polarization of the neuron membrane,
resulting in a more negative charge inside the cell compared to the outside
nodes of Ranvier - CORRECT ANSWER-short sections along myelinated axons where the myelin
sheath is interrupted, facilitating rapid transmission of action potentials
refractory period - CORRECT ANSWER-period during which the neuron membrane is resistant to
starting another action potential immediately after an action potential
