The neurenteric canal is also known as the '''canal of Kovalevsky.''' In the [[Biology:Embryogenesis|development]] of vertebrate animals, during the 6th [[Biology:Carnegie stages|Carnegie stage]], the proximal part of the notochordal canal persists temporarily as the neurenteric canal, which forms a transitory communication between the [[Biology:Amniotic sac|amniotic sac]] and the yolk sac cavities. The neurenteric canal is thought to play a role in the maintenance and adjustment of pressure between the amniotic sac and the yolk sac.<ref>Drew, Ulrich, ''Color Atlas of Embryology'', p. 64, Thieme Press 1995, {{ISBN|9780865775442}}.</ref> When the development of the notochord is complete, the neurenteric canal normally closes. 

A failure of neurenteric canal closure may result in spinal or cranial neurenteric cysts, a pathological finding which may cause symptoms if their location or size cause compression of brain or spine structures.
