QUESTIONS BANK AND VERIFIED CORRECT
SOLUTIONS WITH RATIONALES || 100%
GUARANTEED PASS <RECENT VERSION>
Reticular formation ......ANSWER........network of connected nuclei
that regulate vital reflexes, such as cardiovascular and
respiratory function; maintains wakefulness
Cerebrum ......ANSWER........Largest part of the brain;
responsible for voluntary muscular activity, vision, speech, taste,
hearing, thought, and memory.
Motor neuron ......ANSWER........transmits nerve impulses from the
brain and spinal cord to muscles and glandular epithelial tissues
(efferent)
,age 2 of 43
Wallerian degeneration ......ANSWER........degeneration of a
nerve fiber that has been separated by injury or disease
Nerve Regeneration ......ANSWER........Closer the cell body of the
nerve, the greater the chances that the nerve cell will die and
not regenerate; Crushing injury to the nerve allows recovery
more fully than does a cut injury
Nerve synapses ......ANSWER........Spaces between the neurons of
the brain and central nervous systems that must be crossed for
messages to be sent.
Neuron ......ANSWER........a nerve cell; the basic building block of
the nervous system
Neuroglia ......ANSWER........"nerve glue"; many types of cells
that support, insulate, and protect neurons
,age 3 of 43
Soma ......ANSWER........cell body; densely packed cell bodies in
the CNS are nuclei; ganglia or plexus in PNS
dendrites ......ANSWER........carry nerve impulses toward the cell
body; receptive portion of the neuron that receives a stimulus
and continues further conduction
Axon ......ANSWER........carry nerve impulses away from the cell
body
Sensory neuron ......ANSWER........transmit afferent impulses from
sensory receptors to the CNS
Associational (interneurons) ......ANSWER........transmit impulses
from neuron to neuron
Synaptic boutons ......ANSWER........where neurotransmitters are
stored
, age 4 of 43
Neurotransmitters ......ANSWER........chemical messengers that
cross the synaptic gaps between neurons
Presynaptic neurons ......ANSWER........proximal to the synapse;
relay impulses toward the synapse
Postsynaptic neuron ......ANSWER........distal to the synapse; relay
impulses away from synapse
Reticular formation ......ANSWER........network of connected nuclei
that regulate vital reflexes, such as cardiovascular and
respiratory function; maintains wakefulness
Cerebrum ......ANSWER........Largest part of the brain;
responsible for voluntary muscular activity, vision, speech, taste,
hearing, thought, and memory.
Gray matter ......ANSWER........cell bodies
