The nervous tissue that becomes the spinal cord leaves the cranium through the foramen magnum.

The foramen magnum is a large opening at the base of the skull. It serves as the passage through which the brain connects to the spinal cord. This structure is crucial for the central nervous system, as it allows for the continuation of neural pathways and is surrounded by significant protective structures, including the vertebral column. The proper alignment and functionality of the foramen magnum are essential for the integration of motor and sensory information between the brain and the rest of the body. It is also important in studies of evolution, as its positioning can indicate the posture and locomotion of different species.
