What is the average weight of the human brain?

• A. 2 lbs
• B. 3 lbs
• C. 4 lbs
• D. 5 lbs

Answer: (B)

The average weight of the human brain is approximately 3 pounds, making this the correct answer. This weight can vary slightly depending on factors such as age, sex, and individual anatomical differences. On average, the human brain accounts for about 2% of a person's total body weight, which reflects its importance in terms of function and energy consumption. It is critical for cognitive processes, sensory experiences, and motor function, all of which require a finely balanced structure that is relatively lightweight considering its complexity. The weights represented in the other options are typically higher than what is established through anatomical studies.
