Appears as neural tube on dorsal median plane. 4. th. week brain formation begins at anterior end of the neural tube. Remaining portion of neural tube becomes spinal cord. 4 Major Regions of the Brain. Introduction :. 2 General Classifications. Complete Lesion . A lesion to the spinal cord where there is no preserved motor or sensory function below the level of lesion. Incomplete Lesion. A lesion to the spinal cord with incomplete damage to the cord. There may be scattered motor function, sensory function or both below the level of lesion. Day 3. Meninges. Covers brain and Spinal cord. 3 layers. Dura. Arachnoid. Pia. Dura Mater. Outer most layer.
