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. Multimedial. Unit of Dept. .. of Anatomy JU. A nerve tract is a bundle of nerve fibers (axons) connecting nuclei of the central nervous system . (in the peripheral nervous system this is known . as a nerve fascicle). Day 3. Meninges.
