Foramen magnum
From Wacklepedia - The Free Encyclopedia
In
anatomy, the
foramen magnum is the large hole in the
occipital bone in the base of the
skull, through which the
medulla oblongata (an extension of the
spinal cord) exits the skull vault.
In humans the foramen magnum is farther underneath the head than in great apes. Thus, the neck muscles do not need to be as robust in order to hold the head upright.
