In this article students will learn about the usefulness of pain to survival and about CIPA (congenital insensitivity to pain with anhidrosis). They will learn about the difficulties people with CIPA face because they cannot feel pain, the different types of nociceptors (pain neurons) that exist in humans and the genetics behind CIPA. This is a great in class activity, homework assignment, weekly science reading assignment, sub plan or in school suspension plan.
Congenital insensitivity to pain: Inability to sense pain although sensibility of temperature, pressure, and tickling remains normal. It is caused by a mutation in a gene implicated in the synthesis of a type of sodium channel which is mainly located in neurons associated with the reception and transmission of pain stimulus. source: http://medtempus.com/archives/top-10-weird-anomalies-in-medicine/
