There are a little over 600 muscles in the human body, with most standard anatomy references putting the number of named skeletal muscles at roughly 640–650 , though some experts argue it can range from about 600 up to 840 depending on how muscles are grouped or split.

Why the number is “approximate”

  • Many sources teach that the body has “more than 600 muscles,” which is a safe, rounded figure used in textbooks and health resources.
  • When counting only named skeletal muscles (the ones attached to bones and used for voluntary movement), detailed anatomical lists usually land around 640–650 muscles.
  • Some anatomists count certain muscle parts as separate muscles, which is why estimates can go as high as 800+ in stricter classifications.

Different types of muscles

  • Skeletal muscles : Over 650 named muscles that move the skeleton and give the body shape.
  • Smooth muscles : Found in organs and blood vessels; these are usually counted at the cellular/tissue level, not individually, so the number is effectively in the billions of cells.
  • Cardiac muscle : Functionally, there is one heart muscle type forming the walls of the heart.

Fun extra facts

  • A clear way to answer “approximately how many muscles are there in our bodies?” is: “More than 600, with around 640–650 named skeletal muscles.”
  • The smallest skeletal muscle often cited is the stapedius in the middle ear, and one of the largest and most powerful is the gluteus maximus in the buttocks.
