- Meningomyelocele, myeloschisis [for myelocele (MC)], open spinal dysraphism, spina bifida aperta

- Myelomeningocele (MMC): Open (lacking skin covering) spinal dysraphism in which neural placode (exposed flattened end of elongated spinal cord) protrudes beyond skin surface dorsal to spinal canal
- MC: Open spinal dysraphism with neural placode flush with skin surface
