Usually, the underside again a part of the mind exits out the cranium via a gap referred to as the foramen magnum. That is the place the brainstem connects to the spinal twine. CSF, or cerebrospinal fluid, is the fluid that surrounds the mind, brainstem, and spinal twine, and aids in safety.
With Chiari malformation (CM), the foramen magnum is smaller than normal and the mind is commonly bigger than normal (or the cranium is smaller than normal).
