Cognition- Exploring the science of the mind- Chapter 2 Exam Questions with Verified Solutions Latest
Update 2024 (100% Pass)
all-or-none law - Answers principle that the action potential in a neuron does not vary in strength; the
neuron either fires at full strength or it does not fire at all
action potential - Answers a signal that moves down its axon, which in turn causes the release of
neurotransmitters at the next synapse, potentially causing the next cell to fire.
synapse - Answers the junction between the axon tip of the sending neuron and the dendrite or cell
body of the receiving neuron
presynaptic membrane - Answers the specialized membrane on the axon terminal of a nerve cell that
transmits information by releasing neurotransmitter
postsynaptic membrane - Answers the cell membrane opposite the terminal button in a synapse; the
membrane of the cell that receives the message
neurotransmitter - Answers chemical messengers that cross the synaptic gaps between neurons
axon - Answers "output"; the extension of a neuron, ending in branching terminal fibers, through which
messages pass to other neurons or to muscles or glands
dendrites - Answers "input"; branchlike parts of a neuron that are specialized to receive information.
glia - Answers They help to guide the development of the nervous system in the fetus and young infant;
they support repairs if the nervous system is damaged; they also control the flow of nutrients to the
neurons.
prefrontal - Answers causes problems in problems of planning and implementing strategies. In other
cases, patients with damage here show problems in inhibiting their own behaviors, relying on habit even
in situations for which habit is inappropriate.
aphasia - Answers lesions in areas near the lateral fissure can result in disruption to language capacities
neglect syndrome - Answers individual seems to ignore half of the visual world.
agnosias - Answers disruptions in the ability to identify familiar objects.
apraxias - Answers disturbances in the initiation or organization of voluntary action.
association cortex - Answers regions of the cerebral cortex that integrate simpler functions to perform
more complex functions
contralateral control - Answers with stimulation to the left hemisphere leading to movements on the
right side of the body, and vice versa.
