Neuroblasts

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
Neuroblasts 

embryonic nerve cells that are converted to mature nerve cells, or neurons, during the course of development. In contrast to neurons, neuroblasts partially retain the capacity to divide. In mammals maturation of neuroblasts is completed shortly after birth. For this reason, no new neurons are formed during the subsequent life of the organism. Neuroblastomas are tumors that can arise during the malignant degeneration of neuroblasts.
