NURS 8022 Final Exam Neuro
Complete Questions And Verified
Answers
\Q\.Neuron - ANSWER-✔a nerve cell; the basic building block of the nervous system
\Q\.Neuroglia - ANSWER-✔"nerve glue"; many types of cells that support, insulate, and protect
neurons
\Q\.Soma - ANSWER-✔cell body; densely packed cell bodies in the CNS are nuclei; ganglia or
plexus in PNS
\Q\.dendrites - ANSWER-✔carry nerve impulses toward the cell body; receptive portion of the
neuron that receives a stimulus and continues further conduction
\Q\.Axon - ANSWER-✔carry nerve impulses away from the cell body
\Q\.Sensory neuron - ANSWER-✔transmit afferent impulses from sensory receptors to the CNS
\Q\.Associational (interneurons) - ANSWER-✔transmit impulses from neuron to neuron
\Q\.Motor neuron - ANSWER-✔transmits nerve impulses from the brain and spinal cord to
muscles and glandular epithelial tissues (efferent)
, \Q\.Wallerian degeneration - ANSWER-✔degeneration of a nerve fiber that has been separated
by injury or disease
\Q\.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
\Q\.Nerve synapses - ANSWER-✔Spaces between the neurons of the brain and central nervous
systems that must be crossed for messages to be sent.
\Q\.Synaptic boutons - ANSWER-✔where neurotransmitters are stored
\Q\.Neurotransmitters - ANSWER-✔chemical messengers that cross the synaptic gaps between
neurons
\Q\.Presynaptic neurons - ANSWER-✔proximal to the synapse; relay impulses toward the
synapse
\Q\.Postsynaptic neuron - ANSWER-✔distal to the synapse; relay impulses away from synapse
\Q\.Reticular formation - ANSWER-✔network of connected nuclei that regulate vital reflexes,
such as cardiovascular and respiratory function; maintains wakefulness
\Q\.Cerebrum - ANSWER-✔Largest part of the brain; responsible for voluntary muscular activity,
vision, speech, taste, hearing, thought, and memory.
\Q\.Gray matter - ANSWER-✔cell bodies
