Neurulation is a critical process in the early development of the nervous system, and it involves a specific sequence of events. The correct sequence begins with the formation of the notochord, which is the initial structure providing the necessary signals for the development of the neural plate.

Following the development of the notochord, the neural plate arises. This plate consists of ectodermal cells that will eventually differentiate into neurons and glial cells. The next step involves the formation of the neural folds, which are the edges of the neural plate that begin to rise and fold towards each other. As these folds grow closer, they will eventually converge and fuse to form the neural tube.

The neural tube then gives rise to the central nervous system (CNS), which includes the brain and spinal cord. Therefore, the sequence starting with the notochord, followed by the neural plate, then the neural folds, and culminating in the formation of the CNS properly captures the processes of neurulation.

This understanding of neurulation is essential in embryology, as it highlights the key structures and transformations leading to the establishment of the nervous system.
