Question

seven-year-old samantha suffered trauma to the language centers in the left hemisphere of her brain as a result of a bicycle accident. although she did have some language deficits after the trauma, she eventually recovered much of what she had lost because new growth in unaffected areas of the brain made up for the damage. samanthas recovery is an example of which property or quality of the brain?
○ a healthy genotype
○ plasticity
○ the difference between male and female brains
○ therapeutic effectiveness
question 4 (2.5 points)
norman was injured in a severe car accident, and now, according to his doctors, his hormone levels are highly irregular. in order to have created such havoc in his endocrine system, normans injury probably involved damage to his __________.
○ pancreas
○ gonads
○ pituitary gland
○ pineal gland

Explanation:

Question 3

• "A healthy genotype" refers to genetic makeup, not brain recovery from trauma.
• "Plasticity" is the brain's ability to reorganize and recover by using other areas when damaged, matching Samantha's recovery as new brain growth compensated for trauma.
• The question is about recovery, not gender - based brain differences.
• "Therapeutic effectiveness" implies treatment, but Samantha's recovery was due to brain's own ability, not therapy.

• The pancreas is mainly for digestion and blood sugar, not overall endocrine regulation.
• Gonads (testes/ovaries) affect sex - related hormones, not overall endocrine havoc.
• The pituitary gland is the "master gland" that regulates other endocrine glands; damage here would cause widespread hormone irregularities.
• The pineal gland mainly regulates sleep - wake cycles (melatonin), not overall endocrine system disruption.

Answer:

B. plasticity
