Meninges
This section shows the surface of a neonatal rat spinal cord and the surrounding pia mater. The dura mater and arachnoid layers have been removed. The pia mater lies directly on the surface of the spinal cord and accompanies blood vessels that penetrate the neural tissue. The pia is thicker in the neonate (shown here) than it will be in the adult. 400x
