Notochord - Wikipedia
The notochord is a long, rod-like midline structure that develops dorsal to the gut tube and ventral to the neural tube. The notochord is composed primarily of a glycoproteins core that is encased in a sheath of collagen fibers. This is wound into two opposing helices.
Notochord: Definition, Function and Structure - Biology …
2018年3月15日 · The notochord is an elastic rod which extends through Chordate organisms, providing rigid support. In the more derived Chordates, the Vertebrates, the notochord is replaced by the vertebral column, and becomes the cartilaginous substance between vertebrae.
Notochord - Embryology
Using a single-cell morphometrics pipeline, we quantify the geometries of thousands of amphioxus notochord cells, and project them into a common mathematical space, termed morphospace.
The notochord: structure and functions - PMC
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 arises from the dorsal organizer and it is critical for proper vertebrate development.

Update on the Notochord Including its Embryology, Molecular …
The notochord is a rod-like embryological structure, which plays a vital role in the development of the vertebrate. Though embryological, remnants of this structure have been observed in the nucleus pulposus of the intervertebral discs of normal adults.

2017年10月17日 · Notochord and nerve cord are two characteristic features of chordates. Both notochord and nerve cord is from the neck to the tail in the dorsal part of the body. Notochord is a skeletal rod, and nerve cord is a solid strand of nervous tissue.
Notochord Guides Neural and Spinal Formation - Neuroscience …
6 天之前 · Notochord Role: The notochord acts as a “GPS” in embryos, guiding spine and nervous system development. Lab-Grown Trunk: Scientists recreated notochord tissue and a trunk-like structure with organized neural and bone tissues. Clinical Potential: The model could aid in studying birth defects and back pain linked to intervertebral disc ...
Notochord: Diagram and Features - BYJU'S
Notochord is a flexible rod-like structure that is present in all chordates. It lies dorsally to the gut and ventrally to the neural tube. It gives structural support to the body and is also involved in signalling and induction.
