Question

Quizplus · Accepted Answer

Neural crest cells migrate to many different regions of the body, giving rise to various cell types such as neurons, glial cells, melanocytes, and cartilage and bone of the head and face.

Note: None of the other choices are accurate. The notochord comes from the mesoderm, not the neural crest cells. The overlying ectoderm is derived from the neural tube itself. Neural crest cells do not differentiate into the brain, but rather contribute to the peripheral nervous system. And neural crest cells do not control the segmentation of somatic mesoderm.
