Useless information for the weekend!
It's almost the weekend again, and here is an article containing totally useless information for you! Mind you - if you can figure it out, then you may spend a more relaxed weekend - at least facially....!
Of the 36 muscles used to create facial expressions, only a fraction are used in smiling. The precise number involved can vary, depending on an assortment of factors. Some people, for example, argue that eye crinkles are part of a genuine smile, and that therefore the muscles involved in this activity should be considered part of the number of muscles required to smile. Researchers have also discovered that people from different areas of the world smile differently, although they may use many of the same muscles.
Different types of smiles have also been extensively documented, ranging from the zygomatic or genuine to the utterly fake. People make smile-like expressions for a variety of reasons and in an assortment of ways, and each requires slightly different muscle movements. By studying pictures of people smiling, some skilled researchers can point out the subtle meaning and variation behind the seemingly friendly facial expression.
Six pairs of muscles appear to be directly involved in smiling: the levator anguli oris, levator labii superioris, orbicularis oculi, risorius, zygomaticus major, and zygomaticus minor. This brings the grand total to 12 muscles most probably used to smile. Most authorities who are familiar with their anatomy seem to settle on this number, with 11 muscles being used to frown. That's right: in terms of sheer numbers of muscles involved, it is theoretically easier to frown than to smile. Before one rushes to dispute the saying that it is easier to smile than frown based on this evidence, it is important to be aware that in its resting state, the mouth often approaches a smiling expression, suggesting that minimal effort is required to pull the mouth into a full grin. Furthermore, muscles vary widely in size and strength, so it is entirely possible that people expend less energy in smiling than they do in frowning. Perhaps some intrepid researcher will conduct a detailed study to get to the bottom of the matter.
