The term lamina V refers to a subdivision of the spinal central gray defined on the basis of cytoarchitecture. It is located in the posterior gray column of the spinal cord between lamina IV and two different laminar structures at different levels. In the cervical enlargement and lumbosacral enlargement it is bounded anteriorly by lamina VI; in other parts of the cord lamina VI is not present and its anterior boundary is with lamina VII ( Carpenter-1983 ).
