Chiyero chidiki chinogona kusimbisa rhythmic contraction yemhasuru yakatsetseka pazasi pechibereko, kusimbisa contractility yayo, kukurumidza kuputika frequency, uye kuchengetedza polarity uye symmetry yakafanana neyekubereka kwechisikigo.Nokudaro, inoshandiswa nekiriniki kukurudzira kushanda kana oxytocia.
Chiyero chikuru chinoita kuti uterine tsandanyama chibvumirano nenzira tetanic.Inoshandiswa kukiriniki kudzvanya tsinga dzeropa pakati pemhasuru fibers, kudzivirira kubuda kwepashure uye kusakwana kwemashure ekuberekwa.Inosimudzira lactation, kuderedza mammary duct, uye inosimudzira kubuda kwemukaka kubva muzamu.Zvisinei, haigoni kuwedzera kubudiswa kwemukaka, asi inogona kungokurudzira kubuda kwemukaka.
