A cikin wannan tsari akwai masu ba da amsa ga jijiyoyi, mahaɗan sinadarai waɗanda ke ba da damar watsa sigina tsakanin ƙwayoyin jijiyoyi. Wannan labarin zai tattauna rawar da masu ba da amsa ga jijiyoyi ke takawa a cikin sadarwar ƙwayoyin jijiyoyi, hanyoyin aikinsu, nau'ikan masu ba da amsa ga jijiyoyi, da kuma mahimmancin su ga aikin tsarin jijiyoyi gabaɗaya.
## Tsarin Aiki na Mai Rarraba Jijiyoyin Jijiyoyi
Masu aika sakonnin jijiyoyi kwayoyin halitta ne da ƙwayoyin jijiyoyi suka haɗa kuma aka fitar da su daga tashoshin axon don mayar da martani ga siginar lantarki da ake kira ƙarfin aiki. Lokacin da ƙarfin aiki ya isa tashar axon, membrane depolarization yana faruwa, yana haifar da ions na calcium (Ca²⁺) shiga tashar ta hanyar tashoshin calcium masu gauraya da wutar lantarki. Wannan kwararar ions na calcium yana haifar da vesicles na synaptic waɗanda ke ɗauke da neurotransmitters su haɗu da membrane na presynaptic kuma su saki abubuwan da ke cikinsu zuwa cikin tsagin synaptic ta hanyar exocytosis.
Da zarar an sake su, ƙwayoyin jijiyoyi suna yaɗuwa a cikin ƙwanƙolin synaptic kuma suna ɗaurewa ga takamaiman masu karɓa a kan membrane na postsynaptic. Wannan ɗaurewar yana haifar da canje-canje na tsari a cikin masu karɓa wanda zai iya shafar ƙarfin ion na membrane na postsynaptic, yana farawa ko hana motsin lantarki daga baya.
