Histo-Tips: When differentiating between artierioles and capillaries remember that artierioles have 1-3 smooth muscle layers while capillaries have none, and if you see a single red blood cell filling the whole lumen it is definitely a capillary.
Comments
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.
