The abdominal internal oblique muscle is a special muscle that is located in your tummy area. It is one of the muscles that helps you move when you walk or sit up. Imagine your stomach is like a big balloon, and the internal oblique muscle is like the strings inside the balloon that help it move around.
This muscle is also really important for protecting your body when you're doing things that might be dangerous, like playing sports or lifting something really heavy. It's like a shield that helps keep your organs safe and secure.
So, just remember that the internal oblique muscle is an important muscle in your tummy that helps you move, protect your organs, and stay safe when you're having fun and being active.
