During puberty, which physiologic change is most accurate?

During puberty, which physiologic change is most accurate?

• A. Increase in number of neural connections
• B. Increase in respiratory rate
• C. Increase in the number of neurons
• D. Decrease in basal body temperature gradually

Answer: (A)

During puberty the brain undergoes remodeling driven by rising sex steroids, reshaping neural networks to support new behaviors and hormonal regulation. This period often features growth and strengthening of synaptic connections in key circuits, such as those involved in emotion, reward, and executive function, before later pruning fine-tunes the networks. So an increase in neural connections can describe the dynamic remodeling that occurs during adolescence, making it the best answer among the options. Other choices don’t fit puberty’s typical changes: respiratory rate doesn’t rise as a defining puberty marker, the total number of neurons doesn’t substantially increase, and basal body temperature doesn’t gradually decline as a puberty trend.
