The cervix changes position in response to the same hormones that cause cervical mucus to be produced and to dry up. When a woman is in an infertile phase of her cycle, the cervix will be low in the vaginal canal; it will feel firm to the touch (like the tip of a person's nose); and the os—the opening in the cervix—will be relatively small ...
A cervical pregnancy is an ectopic pregnancy that has implanted in the uterine endocervix. [2] Such a pregnancy typically aborts within the first trimester , however, if it is implanted closer to the uterine cavity – a so-called cervico-isthmic pregnancy – it may continue longer. [ 3 ]

Currently, the pap smear — in which cells taken from the cervix are examined by a doctor “for cervical cancer or cell changes,” per the National Cancer Institute — is the recommended ...
This has implications in scanning nodes for involvement in cervical cancer. [11] After menstruation and directly under the influence of estrogen, the cervix undergoes a series of changes in position and texture.

Effacement translates to how 'thin' the cervix is. The cervix is normally approximately three centimetres long, as it prepares for labour and labour continues the cervix will efface until it is 'fully effaced' (paper-thin). Cervical dilation: Closed 1–2 cm 3–4 cm 5+cm Dilation is a measure of how open the cervical os is.
Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
