Formation of the Neural Tube ________

Question

Formation of the neural tube ________.
A) begins at the anterior (head) end and proceeds toward the posterior (tail)
B) begins at the posterior and proceeds toward the anterior
C) begins in the middle and proceeds toward the head and the tail
D) is random in that it can begin and proceed at any location along the neural plate
E) is caused by compaction of the neural plate

Accepted Answer

The formation of the neural tube starts in the middle and proceeds bidirectionally toward both the anterior (head) end and the posterior (tail) end. This process is crucial for the proper development of the central nervous system in vertebrate embryos.
