The human body does have 206 bones, however, if the sternum is counted as three then the human body would have 208 bones. When people have an abnormal number of bones it is usually due to vertebrae or ribs.

There are two systems of bones and these are the axial skeleton which is the body and the appendicular skeleton which are the limbs.

The number of muscles in the body depends on who you ask. The previous post is accurate. The reason there is some controversy over how many muscles there are in the human body is due to the fact that many experts argue about what constitutes a muscle.

A grown up person including males and females have 206 bones. There is no variation in these bones except in cases of abnormalities.

Similarly the number of muscles in human body is fixed. However, there is no unique way of identifying each muscle in human body as a distinctly separate muscle. Also there is some variation in muscle structure of individuals. Because of these variation in method of classifying muscles different authorities and books may give slightly differing figure for total number of muscles in human body. Most of these authorities agree that human body has about 640 muscles. However some systems of muscle grouping classify as many as 850 muscles.
