The function of the [[Foramen Magnum]] is to allow nerves, blood vessels and fluid to pass in and out of the brain. The [[Foramen Magnum]] is a large hole at the base of the skull. The [[Brain]] stem is essentially seated in the [[Foramen Magnum]] and lying on the basi-occiput. It can be subject to structural pressures that generate misalignment for a variety of different reasons. | The function of the [[Foramen Magnum]] is to allow nerves, blood vessels and fluid to pass in and out of the brain.

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 Oblongata]], passes through the foramen magnum as it exits the cranial cavity. | ||
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.<ref>[https://en.wikipedia.org/wiki/Foramen_magnum Foramen Magnum]</ref> | 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.
