cranial nerves and spinal nerves difference
Unlike spinal nerves, cranial nerves are not spaced at equal distances along the neuraxis, and they have no separation of their sensory (dorsal) and motor (ventral) roots. 01) Mental Health Overview. The main difference between cranial and spinal nerves is that the former is attached directly to the brain while the latter is anchored to the spinal cord which is then attached to the brain. In contrast, spinal nerves emerge from segments of the spinal cord.
