Neural fold
Neural Fold
The Neural Fold (pronunciation: /ˈnʊərəl foʊld/) is a structure that develops during the embryonic stage of an organism. It plays a crucial role in the formation of the neural tube, which later develops into the central nervous system.
Etymology
The term 'Neural Fold' is derived from two words. 'Neural' comes from the Greek word 'neuron' which means 'nerve', and 'Fold' is from the Old English 'faldan', meaning to bend or to fold over.
Function
The Neural Fold is a structure that forms on the dorsal aspect of the embryo during the process of neurulation. The folds elevate and converge towards the midline to form the neural tube. This tube is the precursor to the central nervous system, which includes the brain and the spinal cord.
Related Terms
- Neurulation: The process in embryonic development that leads to the formation of the neural tube.
- Neural Crest: A band of cells that develops from the neural fold. These cells migrate to various parts of the embryo and differentiate into various cell types.
- Neural Plate: A thickened area of the ectoderm from which the neural fold develops.
- Neural Tube: A structure in the early stage of development from which the brain and spinal cord form.
