Orifice Tube Uterine

The orifice of the fallopian tube (OSTUM) is an anatomical term used to refer to the opening through which the fallopian tube connects to the uterus. The fallopian tubes are organs of the female reproductive system that play an important role in the process of fertilization of the egg and its transport to the uterus. The opening of the uterine tube is located on the side wall of the uterus and is connected to its cavity using a funnel.

The opening of the uterine tube has the shape of an oval slit that opens into the uterine cavity. It is surrounded by folds of the uterine lining that form a canal called the fallopian canal. The opening of the fallopian tube can be closed or open depending on the phase of the menstrual cycle. During ovulation, the uterine tube opens, allowing the egg to enter the uterine cavity and be fertilized.

The importance of the fallopian tube opening is that it provides communication between the uterus and the fallopian tubes, which is necessary for the proper functioning of a woman's reproductive system. Any disturbances in the functioning of the fallopian tube can lead to various diseases, such as infertility, ectopic pregnancy and others. Therefore, it is important to monitor the condition of the fallopian tube opening and, if necessary, consult a doctor for diagnosis and treatment.



The opening of the fallopian tube (ostium uteri tubae, PNA, BNA, JNA) is the opening in the uterus through which the fallopian tube connects to its cavity. The uterine tube opening is one of the most important elements in the female reproductive system and plays an important role in the process of fertilization.

The opening of the fallopian tube is located on the side wall of the uterus and opens into its cavity. It is crescent-shaped and has a diameter of about 1-2 mm. The opening of the fallopian tube is covered with a mucous membrane, which provides protection from infections and other damage.

An egg passes through the opening of the fallopian tube, enters the uterus and is fertilized by a sperm. The fertilized egg then moves through the fallopian tubes to the uterus and attaches to its wall. If fertilization occurs, the development of the embryo continues in the uterus.

If the opening of the fallopian tube is damaged or blocked, it can lead to infertility in the woman. Therefore, it is very important to monitor the condition of the fallopian tube opening and promptly consult a doctor if problems arise.

Thus, the opening of the fallopian tube plays an important role in the female reproductive cycle and is an important element of the female reproductive system.
