B. ba tavassuti moddahoi makhsusi khimiyavi, ki nugi torhoi asab judo mekunad, ba vujud meoyad (onhoro nugi torhoi asab judo mekunad). Mediatorho bo molekulahoi membranahoi hujayrai asab tasir namuda, haddi hayajonpazirii onhoro past yo hayajoni barkhestaro «khomush» mesozand.
Mekhanizmi B. hanuz purra omukhta nashudaast, vale ahamiyati on dar tanzimi funksiyahoi gunoguni fiziologii organzim malum meboshad.
