What are the three layers of the neural plate and there derivatives?
1. Endoderm: viscera, liver, respiratory system
2. Mesoderm: bones/muscles, excretory and circulatory system
3. Ectoderm: nervous system, sensory organs, and epidermis
True or False: Brain formation begins when the Neural Tube closes?
_________ _______: thickening of ectoderm on surface of the embryo
________ ________: edges of plate fold and edges grow toward each other.
_______ _________: when folds touch; cervical region 1st
_______ _________: cells adjacent to Neural Tube that separate from tube and ectoderm.
1. Neural Plate
2. Neural Groove
3. Neural Tube
4. Neural creast
_________ _________: Neural Tube Defects =inferior neural tube does not close.
________ ________ ________: ↓ Cellular proliferation.
____________: lack of Folic Acid =failure of cranial apsect of neuraltune to close.
