The thickness of the ventral midline of the spinal cord in human embryos during the fifth week.
The thickness of the ventral midline of the spinal cord was determined in 9 human embryos aged five weeks (developmental stages 13-15). This part of the spinal cord consists of floor plate, mantle and marginal layers. The floor plate ependymal cells form pseudostratified columnar epithelium. The thickness of the investigated structure varied from 20 to 50 micrometers at different levels of the spinal cord.
