Related to neuropore: anterior neuropore

neuropore

 [noor´o-pōr]
an opening in the anterior (rostral) or posterior (caudal) end of the neural tube of the developing embryo; the rostral neuropore is normally closed by 25 to 26 days and the caudal neuropore is usually closed by the end of the fourth week.

neu·ro·pore

(nū'rō-pōr),
An opening in the embryo leading from the neural canal of the neural tube to the exterior of the tube.
[neuro- + G. poros, pore]

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 anatomical charting of human embryonic development. Kinds of neuropores are anterior neuropore and posterior neuropore. See also horizon, neural tube formation.

neu·ro·pore

(nūr'ō-pōr)
An opening in the embryo leading from the neural canal of the neural tube to the exterior of the tube.
[neuro- + G. poros, pore]

neuropore

an opening in the cranial or caudal end of the neural tube of the developing embryo that closes eventually.
