The average human body has about 600 different skeletal muscles. Some are major muscles, like the gluteus maximus and pectoralis major. Others are rather small, but not insignificant, like the coracobracialis and our teres minor.

There are other muscles in the human body that are essential to human life cardiac (heart) and smooth (various organs, like blood vessels, digestive, urinary, & reproductive sysyems), but this question is asking about only the average number of skeletal muscles.
