[[Image:Gray130.png|thumb|right|Schematic of the foramen magnum]] [[Image:Human brain dura mater (reflections) description.JPG|thumb|An opened skull. The foramen magnum is the large hole in the center; labelled '13']] The '''foramen magnum''' is one of several holes in the base of the [[skull]]. Normally the [[spine|spinal cord]] is attached to it. The Foramen Magnum is the largest aperture in the primate body. This hole is located in the base of the [[human]] skull as part of the [[occipital bone]], back of the [[monkey]] skull and in between those locations for apes. It is directly correlated with locomotion ( Humans are bipedal, monkeys quadrupedal and apes are knuckle walkers. ) {{Biology-stub}} == Related pages == * [[brain]] * [[spinal cord]] == References == [[Category:Head (body part)]]
