Are there 60 muscles in the face

The temporal branch was distributed to the orbicularis oculi muscle in all cases and the marginal mandibular branch was distributed to the orbicularis oris muscle in all cases. The zygomatic branch was distributed to the orbicularis oculi muscle in all cases, but it was also distributed to the orbicularis oris muscle in 10 of 25 cases. The buccal branch was not distributed to the orbicularis oris muscle in 3 of 25 cases, and it was distributed to the orbicularis oculi muscle in 8 cases.

There was no significant difference in the variations. The orbicularis oculi muscle and orbicularis oris muscle perform particularly important movements among the facial mimetic muscles. They're fairly flat, difficult to separate from surrounding connective tissue and they all attach to one another. They are very unlike muscles of the limbs, for example. Dr Waller said that actors need not worry because people will compensate for a lack of one muscle by using another to develop a similar expression.

And people can learn to develop a facial expression by practising in front of a mirror. But someone who is unable to raise one eyebrow without raising the other could in fact learn to raise just one.
