This process occurs during labor to prepare the cervix for dilation to allow the fetus to pass through the vagina. While this is a normal, physiological process that occurs at the later end of pregnancy, it can also be induced through medications and ...
The uterine isthmus is the inferior-posterior part of uterus, on its cervical end — here, the uterine muscle is narrower and thinner. It connects the body and cervix. [1] The uterine isthmus can become more compressibile in pregnancy, which is a finding known as Hegar's sign.
