Descriptor notocorda
Scope note: Cuerpo en forma de cordón compuesto por células mesodérmicas cartilaginosas en el dorso de la línea media de los embriones de los CORDADOS. En los vertebrados inferiores es el principal soporte axial. En los vertebrados superiores es una estructura transitoria alrededor de la cual se desarrollarán segmentos de la columna vertebral. La notocorda es también una fuente de señales de la línea media que organiza los tejidos adyacentes, incluyendo el desarrollo del TUBO NEURAL.

Scope note: A cartilaginous rod of mesodermal cells at the dorsal midline of all CHORDATE embryos. In lower vertebrates, notochord is the backbone of support. In the higher vertebrates, notochord is a transient structure, and segments of the vertebral column will develop around it. Notochord is also a source of midline signals that pattern surrounding tissues including the NEURAL TUBE development.
