What is Chorda Dorsalis?
notochord. a cylindrical cord of cells on the dorsal aspect of an embryo, marking its longitudinal axis; a defining characteristic of all chordates. It is the center of development of the axial skeleton.
The chorda dorsalis (" back string ", from Latin chorda " string " and dorsum "back") or notochord , axis rod , rarely spinal column and often plain chorda , is the original inner axis skeleton of all chordata (chordata) and for them the eponymous feature . The Chorda dorsalis is a long, thin and pliable rod in the back area.
All chordates, at least as embryos, create a dorsal chorda that is sometimes surrounded by a connective tissue chorda sheath. [1] The Chordata includes three still living animal groups: the Lanzettfischchen (Leptocardia), the skull Animals (Craniata) and tunicates (tunicates). In the lancelet and some adult skulls, the dorsal aspect of the chord runs through the entire length of the body between the neural tube and the intestinal canal . In the other today 's skull animals, it is completely or except for small remnants, because they from the spine (and theIntervertebral discs ) [2] is replaced. In contrast, tunicates (Tunicata) form a back string only in the rowworm of the larva . [4]
The Chorda dorsalis has both a skeletal and a developmental function. In its skeletal function, it serves as a resilient internal skeleton , which stretches and stabilizes the body shape, [5] as well as a point of attachment for muscles that curl the body. The developmental function is essentially to initiate the formation of certain other tissues and organs during embryonic development , including the central nervous system .
