Describe the process of neurulation in chick.

Neurulation in chicks is the process during early embryonic development where the neural tube forms from the neural plate. It marks the beginning of the central nervous system's (CNS) development, a critical step in vertebrate embryogenesis. Neurulation in chicks proceeds in stages, starting from the formation of the neural plate to the closure of the neural tube, involving intricate cellular movements and differentiation.

The process begins with the formation of the neural plate. During the early stages of chick embryonic development, the ectoderm, the outermost germ layer, thickens along the dorsal side of the embryo. This region, known as the neural plate, forms under the influence of signals from the underlying notochord and mesoderm. These signals induce the overlying ectoderm to differentiate into neural ectoderm, which is committed to forming the neural tissues.

As development progresses, the edges of the neural plate begin to elevate, creating neural folds. This _________ _______ ______ ___ ________ _______.
