Approximately how many muscles are in the human body?

The human body consists of over 600 muscles, which is a well-established fact in anatomy and physiology. These muscles can be categorized into three main types: skeletal, smooth, and cardiac muscles. Skeletal muscles, which are responsible for voluntary movements, make up the majority of the total muscle count, typically accounting for about 640 of them, depending on various factors such as individual variations and anatomical definitions.

Understanding this number is important in yoga teacher training, as it provides insight into the complex structure of the human body and how different muscles function during various poses and movements in yoga practice. This knowledge can enhance a teacher's ability to instruct students about their bodies, help prevent injuries, and provide modifications based on a student’s individual muscle strength and flexibility.

Other options listed either underestimate or exaggerate the total number of muscles in the human body, leading to confusion or inaccuracies regarding human anatomy.
