In vertebrates the notochord is an embryonic structure that disintegrates, as the vertebrae develop, to become the nucleus pulposus in the intervertebral discs of the vertebral column. In …

The notochord is an embryonic midline structure common to all members of the phylum Chordata, providing both mechanical and signaling cues to the developing embryo. In vertebrates, the …

notochord, flexible rodlike structure of mesodermal cells that is the principal longitudinal structural element of chordates and of the early embryo of vertebrates, in both of which it plays an …

Aug 25, 2025 · The notochord is a flexible, rod-like structure present during the embryonic stage of all chordates, a diverse group of animals including vertebrates, tunicates, and lancelets. It …

Aug 3, 2025 · The notochord, also known as chorda dorsalis, represents the earliest fetal axial skeleton, extending from the Rathke pouch to the coccyx. It is a primitive cell line from which …

Notochord is a flexible, rod-shaped supporting structure that is one of the distinguishing features of the phylum Chordatas, being found at some point in the life cycle of all chordates …

It is an early forming midline structure in the trilaminar embryo mesoderm layer initially ventral to the ectoderm, then neural plate and finally neural tube. This is a transient embryonic anatomy …

The notochord is a flexible, rod-shaped structure found in the embryos of all chordates that serves as a primary axial support during early development. It plays a critical role in the development …
