The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm. Throughout gestation, [1] the uterus enters a state of uterine quiescence due to various neural and hormonal changes. During this state, the uterus undergoes little to no contractions, though ...
The uterus is located in the middle of the pelvic cavity, in the frontal plane (due to the broad ligament of the uterus). The fundus does not extend above the linea terminalis, while the vaginal part of the cervix does not extend below the interspinal line. The uterus is mobile and moves posteriorly under the pressure of a full bladder, or ...
Illustration of fundal height at various points during pregnancy. Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry ...
The uterus changes in size from one kilogram to 60-80 grams in the space of six weeks. ... The caloric requirement for a non-breastfeeding, non-pregnant woman changes ...
Reed says the size of the baby and the uterus and the amount of amniotic fluid, which cushions the baby in the amniotic sac, can account for a larger or smaller bump, along with one’s height and ...
The optimal endometrial thickness is 10mm. Nevertheless, in human a perfect synchrony is not necessary; if the endometrium is not ready to receive the embryo an ectopic pregnancy may occur. This consist of the implantation of the blast outside the uterus, which can be extremely dangerous. [20] Triple-line endometrium measuring 7mm.
The pelvic exam during pregnancy is similar to the exam for non-pregnant women; however, more attention is given to the uterus and cervix. The size of the uterus is assessed at the initial visit, and the growth of the uterus is assessed at subsequent visits. In the first trimester the uterine size can be assessed on bimanual examination ...
