Document Summary
Task 2 the nervous system ii: fill in a and make a connection to fore- mid- and hindbrain. 175-179 (a) the brain consists of a flat sheet of cells (3 weeks). The ectoderm forms the nervous system and the skin. It contains the neural plate in the middle. The mesoderm forms the bones of the skeleton and the muscles. The endoderm forms the internal organs. (b) the neural plate forms a groove called the neural groove that runs from front to back (rostral to caudal). The walls that form around the groove are called neural folds. (c) the neural folds fuse together on top (dorsally) and the neural groove becomes the neural tube. The entire nervous system derives from the walls of the neural tube. (d) parts of the neural folds are pinched off and lies on both sides (lateral) of the neural tube to become the neural crest.
