How many muscles does the human body contain approximately?

The human body contains more than 500 muscles, making this the accurate choice. This total includes various types of muscles: skeletal muscles, which are attached to bones and enable voluntary movement; smooth muscles, found in internal organs and blood vessels that operate involuntarily; and cardiac muscle, which composes the heart. The skeletal muscles alone make up a significant portion of this total, with estimates around 600. Therefore, recognizing that the complete count of muscles in the body exceeds 500 provides a solid understanding of human anatomy and the complexity of muscle tissue types.

The other options do not align with the current understanding of human anatomy. A count of less than 200 significantly underestimates the vast number of skeletal muscles. Similarly, while about 300 seems a plausible guess, it is still less than the actual total. The estimate of roughly 700, while closer, also exceeds the generally accepted figure in anatomy. Thus, the option indicating more than 500 accurately reflects our knowledge of human muscles.
