Neuromere
Neuromere (pronunciation: /ˈnʊərəˌmɪər/; etymology: from Greek neuron meaning "nerve" and meros meaning "part") is a term used in neuroanatomy to describe the segmented nature of the early developing vertebrate central nervous system.
Definition
A neuromere is a transiently segmented structure in the early development of the vertebrate embryo. It is a fundamental unit of organization of the neural tube, which is the precursor to the central nervous system.
Function
The function of the neuromere is to serve as a basis for the regional specification of the neural tube. This regional specification is crucial for the correct formation of the brain and spinal cord.
