Neural fold

Definition

Neural folds are paired structures that form along the dorsal surface of the embryonic disc, eventually folding towards each other to create the neural tube, which is the precursor to the central nervous system (CNS). This process occurs during the early stages of embryonic development.

Neural Tube:

The neural tube is an embryonic structure that develops into the brain and spinal cord, forming from the fusion of neural folds.

Neurulation:

Neurulation is the process during early fetal development where the neural plate forms into the neural tube, involving the formation and fusion of neural folds.

Ectoderm:

The ectoderm is one of three primary germ layers in the embryo; it gives rise to both external structures such as skin and internal structures like the CNS, beginning with structures like the neural fold
