How many facial muscles do people have?
Muscles are essential for movement. And also for the seemingly simplest processes, such as B. opening the mouth to eat or to kiss goodbye, muscles are needed. The facial and chewing muscles are hidden under the skin of the face. The latter is also one of the strongest muscles in the body. But how many facial muscles do humans have to express their feelings on their faces?
The facial muscles comprise around 24-34 muscles. The numbers can vary widely depending on the source as some muscles are compound muscles. Then it depends on whether the individual muscles or the total muscle are counted.

Some scientists once took the trouble and calculated that in 70 years a person will spend around 76 days training their facial muscles by kissing.
- About 17 facial muscles are needed to be able to laugh. There are also many other muscles of the neck and upper chest as well as the diaphragm. This shows that even activities that can only be read on the face need far more muscles.
- The most famous facial muscles are the circular muscles around the eyes and around the mouth. The eye muscles allow you to squint or open your eyes wide. In addition, the sphincter muscle around the mouth helps to pursue the lips or to respond to a funny situation with a big grin.
Humans have chewing muscles with a lot of bite
The masticatory muscles have the strongest muscle in the human body, the masseter muscle (= large masticatory muscle). Unlike the facial muscles, the masticatory muscles are only formed by 4 large muscles, which have their main attachment points on the temporal bone and the lower jaw. The normal chewing pressure for many people is around 400–500 N. This corresponds to around 40 to 50 kilograms. In extreme situations such as grinding teeth at night, this pressure can even reach several hundred kilograms.
