Relating to the medulla oblongata (the brain's bulb) and the spinal cord, or describing connections and pathways between them.
From 'bulbo-' (the medulla oblongata) and 'spinal' from Latin 'spinalis' (relating to the spine), describing the relationship between brain and spinal cord.
Bulbospinal pathways control critical life functions—damage to these connections can affect breathing and heart rate, which is why high spinal injuries near the medulla are so dangerous.
