What is the term for repetitive or reflexive movements after death? (Not Rigor Mortis)

Question

I know that Rigor Mortis may cause post-Mortem movement like stiffening, but I'm referring to actions like grasping or movement of eyes repetitively. Like when you kill a bug but it continues to try to bit you or crawl.

Answer 1

I don't know if there is a name specifically for that, I think they're just referred to reflexive muscle spasms.
