c. It is not fully developed at birth.
d. Infants are not as sensitive to central nervous system drugs as older children and adults.
D
Infants are much more sensitive to central nervous system drugs than older children and adults, as the blood-brain barrier is not fully developed at birth.
From a therapeutic perspective, the blood-brain barrier is a mixed blessing. On the positive side, it protects the brain from injury by potentially toxic substances. However, it also makes it difficult to treat diseases affecting the brain.
The blood-brain barrier is not fully developed at birth; no further teaching is required.
