Formation of the neural tube epithelium basement membrane during secondary neurulation in the chick embryo

Neurulation, the formation of the neural tube, is an important process in the development of vertebrates. Because this organ ultimately becomes the central nervous system of the organism, the proper development of a fully-functioning neural tube is paramount to its survival. Neural tube defects, like spina bifida and anencephaly, are among the most common congenital malformations present in live human births. The prevalence of these defects is a definite concern to medicine and human health.
