The spelling of "orificium internum uteri" can be challenging for non-Latin speakers. The word is pronounced as /ɔːrɪfɪsiəm ɪntərnuːm juːtəraɪ/, with the stress on the first syllable. "Orificium" means an opening or entrance, "internum" means internal, and "uteri" pertains to the uterus. The word refers to the internal opening of the uterus, and its correct spelling is vital for medical professionals. It is important to learn the correct pronunciation and spelling of medical terms for clear and accurate communication in the healthcare industry.
Orificium internum uteri, alternatively known as the internal orifice of the uterus, is a defined anatomical term used in gynecology and reproductive medicine. It refers to the opening of the uterine cavity into the cervical canal, which is the passageway that connects the uterus with the vagina.
Located within the cervix, the orificium internum uteri serves as the lower entrance to the uterus and marks the boundary between the uterine cavity and the cervical canal. This narrow channel is lined with specialized cells known as the cervical epithelium, which secrete mucus and undergo changes during different stages of the menstrual cycle and pregnancy.
The orificium internum uteri plays a crucial role in various reproductive processes. For instance, during menstruation, the cervix constricts, partially closing the orifice to prevent blood from flowing back into the uterus. Conversely, during ovulation, the orifice relaxes and loosens to allow the passage of sperm through the cervical canal and into the uterus, enabling fertilization.
This anatomical structure is of particular interest and importance in obstetrics and gynecology, as it can affect fertility, contraception, and the progress of labor. Abnormalities or disorders in the orificium internum uteri, such as stenosis (narrowing) or incompetence (inability to stay closed during pregnancy), may require medical intervention or treatment.
Os uteri internum, a slightly constricted portion of the cavity of the uterus marking the separation of the cervix from the corpus uteri.
