Fetal cephalic position refers to the position of the fetus with the head facing down and the buttocks facing up, and is often referred to as longitudinal birth style and head first exposure. Fetal birth style refers to the relationship between the longitudinal axis of the fetus and the longitudinal axis of the mother. A fetus whose longitudinal axis is parallel to the longitudinal axis of the mother is referred to as longitudinal birth style. Fetal head first refers to the part of the fetus that is the first to make the pelvic inlet, and the longitudinal delivery style has cephalic and breech presentation. The fetal head position is often cephalic. It is usually normal for the fetus to automatically shift to a head-down, breech-up position later in gestation. Fetal position is often diagnosed by a combination of abdominal palpation, vaginal or anal examination, and ultrasound. If there is any discomfort, it is recommended to seek prompt medical attention for diagnosis and treatment.
