NR 304 QUIZ 2 || Acknowledged Answers 100%.
nervous system correct answers the network of nerve cells and fibers that transmits nerve
impulses between parts of the body. Divided into two parts Central nervous system (CNS), and
Peripheral nervous system (PNS),
Peripheral Nervous System (PNS) correct answers Includes all nerve fibers outside brain and
spinal cord
Includes 12 pairs of cranial nerves, 31 pairs of spinal nerves, and all their branches
Carries sensory (afferent) messages to CNS from sensory receptors
Motor (efferent) messages from CNS to muscles and glands, as well as autonomic messages that
govern internal organs and blood vessels
cerebral cortex correct answers outer region of the cerebrum, containing sheets of nerve cells;
gray matter of the brain
Frontal lobe correct answers concerned with personality, behavior, emotions, and intellectual
function.
Broca's area correct answers It is in frontal lobe meditate speech production
parietal lobe correct answers portion of the cerebral cortex lying at the top of the head and
toward the rear; receives sensory input for touch and body position. primary center for sensation
Occipital lobe correct answers A region of the cerebral cortex that processes visual information.
primary visual receptor center
Temporal lobe correct answers A region of the cerebral cortex responsible for hearing and
language. behind ear, has primary auditory reception center, taste, and smell
, Wernicke's area correct answers usually in the left temporal lobe. controls language reception - a
brain area involved in language comprehension and expression;
Damage to Cerebral Cortex correct answers Damage to specific cortical areas produces a
corresponding loss of function:
Motor weakness
Paralysis
Loss of sensation
Impaired ability to understand and process language
Damage occurs when highly specialized neurologic cells are deprived of blood supply, such as
when a cerebral artery becomes occluded.
Aging adult considerations neurological system correct answers Atrophy with steady loss of
neuron structure in brain and spinal cord
Velocity of nerve conduction decreases making reaction time slower in some older persons.
Increased delay at synapse results in diminished sensation of touch, pain, taste, and smell.
Motor system may show general slowing down of movement, muscle strength, and agility
decrease.
Progressive decrease in cerebral blood flow and oxygen consumption may cause dizziness and
loss of balance.
Culture and Genetics: neurological system correct answers Racial/ethnic disparity noted relative
to strokes
5th most common cause of death in the United States
Screening for hyperlipidemia and HTN with statin treatment
Geographic disparity noted relative to strokes
Existence of "Stroke Belt" —8 states with increased stroke mortality
