The anterior median fissure of the spinal cord has an average depth of about 3 mm, but this is increased in the lower part of the medulla spinalis.
It contains a double fold of pia mater, and its floor is formed by a transverse band of white substance, the anterior white commissure, which is perforated by blood vessels on their way to or from the central part of the medulla spinalis.
