4 theories of labor
uterine stretch theory oxytocin and prostaglandin progesterone deprivation theory prostaglandin theory placental aging theory
theory: works together to inhibit calium binding in muscle cells raising intracellular calcium thus activating contractions
oxytocin and prostaglandin
theory:
it is known that uterus is a hollow organ. And when an hollow organ reaches its peak of stretchability, it tries to contract to expel its content. with the help of the prostaglandin, contraction of the uterus would indicate a sign of labor
uterine stretch theory
theory:
this theory says that this hormone is responisble for stimulating myometrium or the muscle of the uterus to contract, thus labor begins
prostaglandin theory
theory:
when placenta reaches its peak of performance. Its function starts to degenerate due to the decrease of the homrones estrogen and progesterone. Which triggers the labor
placental aging theory
theory:
a decrease in progesterone causes uterine changes, thus labor pains occur. Progesterone is known to inhibit uterus mobility, and with the deprivation of this hormone it causes changes.
