How many muscles does a human body have?
There are approximately 640 muscles in the human body, although estimates have been made for a total count between 640 and 850 (depending upon whether a muscle is considered single or a group of several muscles). These are further categorized based on which body part they relate to. Using this classification system, we have muscle classes that group those belonging to the head, neck, torso, upper limbs and lower limbs.
