Did you know humans are capable of making 10,000 unique facial expressions ????! In the 1960s, American psychologist Paul Ekman disproved theories that human expressions were learned. Instead, he showed that our facial expressions are innate and universal. Let\u2019s take a closer look at muscles that are responsible for facial expressions\u2026 <\/p>\n\n\n\n

The facial muscles are the only group of muscles that insert into the skin. They are located in the subcutaneous tissue, originating from bone or fascia. When contracting, the muscles pull on the skin and exert their effects ?.  <\/p>\n\n\n\n

This group of muscles comes from the same embryonic origin, the 2nd<\/sup> pharyngeal arch. Therefore, they share the same main source of innervation, the facial nerve. <\/p>\n\n\n\n

We can split the facial muscles into the following 3 groups: <\/p>\n\n\n\n
