neuropore /neu·ro·pore/ (-por) the open anterior (rostral n.) or posterior (caudal n.) end of the neural tube of the early embryo, which closes as the embryo develops.
neuropore [noo͡r′ōpôr] Etymology: Gk, neuron + poros, pore the opening at each end of the neural tube during early embryonic development, leading from the central canal of the neural tube to the exterior. The closure of these apertures as the tube grows and differentiates occurs with such precision that they are used to indicate horizons XI and XII in the systematic anatomic charting of human embryonic development. Kinds of neuropores are anterior neuropore and posterior neuropore. See also horizon, neural tube formation. neuropore an opening in the cranial or caudal end of the neural tube of the developing embryo that closes eventually. How to thank TFD for its existence?
