You have the pia mater
You have the pia mater labeled incorrectly. The pia mater is the layer that surrounds the surface of the spinal cord- it is visible in your image at the bottom. Please fix the pia mater label to reflect this. Also please include the total magnification (10 times objective mag) in the key.
