there is 2 steps:
1- Penetration:
The anaesthetic has to penetrate the nerve's shell. To do so, it has to decompose in two forms: RH- and RH+. The anaestheticc is made to decompose in 25% rh- and 75% rh+. the rh- will penetratee the nerve (its lipophilic), thus there will now be 100% RH+ outside and 100% rh- inside. those two will therefore decompose as well 75 - 25, until there is an balance between the outer and inner of the nerve. (basic chemistry)
2- inactivation of calcium channels
the rh+ form will mechanically disable the calcium channels of the nerve, therefore disabling the functionnality of that nerve.
