Questions with Correct Solutions
Question:
1. what changes in the CNS happen with age
Answer:
-decrease brain mass -decline in the number and efficiency of neurons -slower nerve
conduction velocity -decreased neurotransmitters
Question:
2. therapeutic considerations in the elderly for CNS
Answer:
-significant loss of cerebral cortex and cerebellar areas= loss of cognition and balance -slower
responses increase the energy expenditure during activity -sluggish or slower righting
responses (prolonged inefficient muscle contraction) -sarcopenia, slowing neuromuscular
junction leading to atrophy and inefficient muscle function
Question:
3. what is cerebral cortex responsible for
Answer:
-made up of gray matter -responsible for higher level functions (temporal, occipital, frontal,
parietal)
Question:
4. What is the cerebellum responsible for
Answer:
-regulates movement, coordination, and posture -motor learning -muscle tone
Question:
5. what changes in the PNS come with age
Answer:
-decreased nerve cells -decreased blood flow to nerve cells
Question:
6. therapeutic considerations for PNS with the elderly
Answer:
-slower reaction time -increased in activity improves blood flow to the nerve
