Decubitus is usually defined as an enlarged cervix.
It is an important reference point during labor and delivery, and is used to determine whether a woman has reached term or not.
Normally, the cervical opening is about the size of an adult’s fingertip. During labor, the cervical opening is dilated to a certain degree to facilitate the delivery of the baby.
A woman’s cervical opening changes from its initial state to an opening of about 10 centimeters when she has her tenth finger, and the dilatation of the cervix is usually checked surgically.
It is recommended to go to the hospital in the late stages of pregnancy when the uterus is dilated in order to avoid other abnormalities.
