Risus sardonicus
The risus sardonicus ( Latin for sardonic laugh , often inaccurate as the "devil grin" translated) is a symptom of infection with Clostridium tetani . The name is derived from the mythical drug Herba sardoni (c) a , which was interpreted as a saffron vine umbel .
These bacteria cause tetanus ( tetanus ). Due to the cramping of the muscles, the facial muscles contract and cause an expression of malicious grin, the Risus sardonicus . The patient can no longer resolve this grin .
Risus sardonicus also occurs with poisoning with strychnine .
