Document Summary
Neuron physiology vii - organization of the cns. Week 3: neural tube has formed from migration of neural cells to the middle of the embry. Cells rearrange in order to create the framework of the nervous system. Week 4: the forebrain, midbrain and hindbrain complete specialization. Week 6: all internal cavities are formed. 4 ventricles in the brain and the central canal of the spinal cord. The nervous tissue of the neural tube has differentiated into the regions of the brain present at birth. The remainder of development is characterized by cerebral enlargement. The brain consists of the: forebrain: May look identical but have many different functions. Lateral ventricles (2) and the 3rd ventricles. Fourth ventricle is in the brain stem. Important for the control of eye movement: hindbrain. Only part of the hindbrain not in the brain stem. White matter is composed almost entirely of bundles of myelinated axon.
