Abstract
• The spinal cord plays a significant role in the nervous system. It deserves a deeper understanding of its anatomical and physiological make up due to its complicated connections, developmental defects, lesions, and clinical presentation.
• The spinal cord is cylindrical and elongated in structure throughout the spinal canal. It is an extension of the lower part of the brain stem, i.e the medulla oblongata.
• In an adult, it starts at the first cervical vertebra and terminates at the first lumbar vertebra. In young children, the spinal cord extends beyond the vertebral column and normally terminates in the lower portion of the first lumbar vertebra. Its terminal end, the Conus medullaris, is characterized by a conventional cone shape (CM).
• The CM moves from the L3 to the S5 vertebrae during birth as the foetus develops. The adult spinal cord typically ends opposite the first and second lumbar vertebrae (L1-L2), between L3 and T12. The CM, formed from the neural tube, ascends in the vertebral canal and ends between the upper T12, L1, L2 and L3 discs.
• The present study was conducted in other to determine the types and locations of CM in Egyptian patients.
