Chapter 7: Neurulation and the Formation of Axial Structures Neurulation The stage of organogenesis in vertebrate embryos‚ during which the neural tube is transformed into the primitive structures that will later develop into the central nervous system. In development‚ this starts with the first traces of formation of the neural plate and ends with closure of the neural tube. Induction Process by which the presence of one tissue influences the development of another. Some considerations:

Ichthyosis Vulgaris Ichthyosis vulgaris is a member of a group of cutaneous disorders of keratinization and appear both clinically and histologically. Ichthyosis vulgaris disrupts this balance either because too many replacement skin cells are produced or because the skin cells do not separate well from the skin surface when it is their time to drop off. The result is that skin cells accumulate into thick flakes that adhere to the body. Ichthyosis vulgaris can be a nuisance‚ but rarely affects overall
