Foramen magnum
The
foramen magnum
is a large oval opening in the
occipital bone
of the
human skull
. It is one of the several oval or circular openings (
foramina
) in the
base of the skull
. The
spinal cord
, an extension of the
medulla
, passes through the foramen magnum as it exits the
cranial vault
. Apart from the transmission of the medulla oblongata and its membranes, the foramen magnum transmits the
vertebral arteries
, the
anterior
and
posterior spinal arteries
, the
tectorial membranes
and
alar ligaments
. It also transmits the spinal component of the
accessory nerve
into the skull.
