membranes‚ umbilical cord‚ and placenta are expelled from the uterus. (Medscape 2014) Etiology: According to research‚ the exact cause of labor has yet to be discovered. Labor normally starts when the fetus is mature enough to adjust easily to extra uterine life but before it grows so large that vaginal birth is impossible. Natural labor begins when forces favoring continuation of pregnancy are offset by forces favoring its end. (Murray 2014) Pathogenesis: There are signs a woman will experience when

using an intrauterine pressure catheter (IUPC). It is inserted into the uterine cavity through the cervical os. It reflects the pressure inside the uterine cavity. As the pressure changes‚ it traces on the graph paper. The IUPC can measure the resting tone of the uterus between contractions‚ referred to as intensity. An advantage of an IUPC is that it provides a near-exact pressure measurement for contraction intensity and uterine resting tone. The sensitivity of the IUPC allows for very accurate timing

Equine Reproductive System Tim Heckart In exploring the reproductive system of the horse we must first understand that this system is made up of physical structures and hormonal or chemical secretions‚ actions‚ and reactions. While the physical structures are readily identifiable‚ the hormonal systems are a bit more obscure. Some of these hormonal actions and reactions are still not fully understood today. We begin with the delivery of a Filly. At this stage in her life she already has all

The onset of labor is defined as regular‚ painful uterine contractions resulting in progressive cervical effacement and dilatation. Cervical dilatation in the absence of uterine contraction suggests cervical insufficiency‚ whereas uterine contraction without cervical change does not meet the definition

Contraction of myoepithelial cells around breast ducts and alveoli to stimulate milk flow and it is queried as to whether oxytocin release actually causes the onset of labor. Oxytocin primarily affects uterine smooth muscle - increasing both the frequency and duration of action potentials during uterine contractions. Oestrogen enhances the effects of oxytocin by lowering the membrane

The aqueous extract at dose of 400 mg/kg had lesser activity then ethanolic extract at dose of 400 mg/kg‚ which exhibits more significant estrogenic activity with increase in uterine weight‚ when compared to control. It is well known fact that estrogenic substances inhibit pregnancy by suppressing the level of both follicular stimulating hormone (FSH) and luteinizing hormone (LH)‚ which in turn prevent the implantation.

PLACENTAL STAGE Stage 3 refers to the delivery of the placenta. At stage 3‚ the baby has already been born however‚ contractions will continue until the placenta is delivered. The placenta separates from the wall and natural removal occurs by uterine contractions. The birth of the placenta takes place 5 – 30 minutes after the birth of the baby. The placental stage is crucial because of the possibility of maternal hemorrhage. Signs of the placental separation are as follows: a. The uterus
