The neural crest is important because several significant vertebrate features develop from it.
a. true
b. false

a. True

Explanation:

The neural crest is formed from the neuroectodermal cells and is divided into two parts that originate the spinal and cranial ganglia. The cells of the neural crest originate the spinal ganglia and the autonomic nervous system ganglia and form the sheath of nerves and meninges of the brain. The neural crest is important for bone formation, cartilage, neurons, connective tissue of the face, skin pigment cells, cardiovascular system, smooth muscle cells, glial cells, among other structures.

With this we can say that it is true, the neural crest is important because several significant characteristics of vertebrates develop from it.
