Neuroanatomical Structures of Spinal Cord - A Review

This review aims to highlight the the termination of spinal cord in different species and to focus on gross morphology, cross sections at different levels, compound light microscopic view and electron microscopic view, in vitro and the images under Computed Tomography and Magnetic Resonance Imaging, in vivo. The spinal cord starts from the foramen magnum and ends in to conus medullaris. The caudal extremity of the spinal cord tapers to a point caudal to the lumbar segments and is referred to as the conus medullaris. The cross section of spinal cord varies at different level. Histologically the spinal cord is composed of neurons and neuroglia. Ultrastructurally the organells of the different components of spinal cord can be visible.
