Embryo spinal cord. Coloured light micrograph of a section through the spinal cord of a 6-week-old human embryo. This spinal cord precursor is known as the neural tube. The central canal (white) is surrounded by structures that will form the grey matter of the central nervous system. At top (dorsal side,facing the back) is the roof plate. Below this is the sulcus limitans (dark pink fibres) and the alar plate (mid-pink,upper centre region). The lower centre region (also mid-pink) is the basal plate. At bottom (ventral side,facing the chest) is the floor plate. The pale pink region around these features will become white matter. The red regions are somites,structures that form skin,muscle and vertebrae (backbones) | |
