Its lateral edges soon elevate to form the neural folds (. Fig. 17.. With further development, the neural folds continue to elevate, approach each other in the midline, and finally fuse, forming the neural tube (. Brain. Spinal Cord.

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. 9. th. grade Health. MRS. EGGLER.
