Approximately how many muscles are in the human body?

• A. Around 200
• B. Around 1000
• C. More than 2000
• D. More than 600

Answer: (D)

There are roughly six hundred muscles in the human body, most of which are skeletal muscles that move the skeleton and maintain posture. This number can vary a bit depending on how tiny muscles are counted, but anatomy references commonly cite about 600–700 skeletal muscles, so saying more than 600 matches the standard estimate. The other numbers don't fit what textbooks teach about the total muscle count in an adult; they’re either too low to account for all major muscle groups or too high for typical counts. So more than 600 is the best answer because it aligns with the commonly taught range for the total muscle count.
