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 Q.White matter - ANSWER-myelinated fibers Q.Prefrontal lobe - ANSWER-goal-oriented behavior, short-term or recall memory Q.Premotor - ANSWER-Programs motor movement; basal ganglia (extrapyramidal system; efferent pathways outside medulla pyramids) Q.primary motor area - ANSWER-primary voluntary motor area; corticospinal tracts descend down spinal cord; contralateral control Q.Broca's area - ANSWER-Controls language expression - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech. Q.Parietal lobe - ANSWER-somatic sensory input Q.Occipital lobe - ANSWER-visual cortex Q.Temporal lobe - ANSWER-primary auditory cortex Q.Corpus callosum - ANSWER-connects the two hemispheres Q.limbic system - ANSWER-Primitive behavioral responses - visceral reaction to emotion, feeding behaviors, biologic rhythms, and sense of smell; Expression of affect (emotional and behavioral states) - mediated by the limbic system and prefrontal cortex; Consolidation of memory
