FAQs on Cardinal Movements at Birth Video Lecture - MBBS

1. What are cardinal movements at birth?
Ans. Cardinal movements at birth refer to the specific sequence of movements that a baby goes through during the process of labor and delivery. These movements are essential for the baby to navigate through the birth canal and be born successfully.
2. How many cardinal movements are there during birth?
Ans. There are typically seven cardinal movements during birth. These movements include engagement, descent, flexion, internal rotation, extension, restitution, and external rotation. Each movement plays a crucial role in facilitating the baby's passage through the birth canal.
3. What is the purpose of flexion in cardinal movements at birth?
Ans. Flexion is an important cardinal movement that occurs during birth. It refers to the baby's chin bending towards their chest, causing the head to become rounded. This movement helps the smallest diameter of the baby's head (the suboccipitobregmatic diameter) to align with the smallest diameter of the mother's pelvis, facilitating a smoother passage through the birth canal.
4. How does internal rotation contribute to the cardinal movements at birth?
Ans. Internal rotation is a cardinal movement where the baby's head rotates to align with the mother's pelvis. This movement allows the baby's head to navigate the curved shape of the birth canal. Internal rotation typically occurs as the baby descends through the pelvis, ensuring proper alignment for the subsequent movements of extension and delivery.
5. What is the significance of external rotation in the cardinal movements at birth?
Ans. External rotation, also known as restitution, is the final cardinal movement that occurs during birth. It refers to the baby's head turning back to its original position after delivery. This movement is significant as it allows the baby's shoulders to align with the mother's pelvis and facilitates the delivery of the rest of the baby's body. External rotation ensures a smooth and successful birth process.
