Destruction of the Embryonic ____________ Will Prevent Formation of the Nervous

Question

Destruction of the embryonic ____________ will prevent formation of the nervous system.
A)ectoderm
B)mesoderm
C)endoderm
D)mesoglia

Accepted Answer

The nervous system is derived from the ectoderm layer during embryonic development. Therefore, destruction of the embryonic ectoderm will prevent the formation of the nervous system. The mesoderm gives rise to muscles, bones, and other connective tissues, and the endoderm gives rise to the gut and respiratory system. Mesoglia is not a defined germ cell layer.
