Notochord
notochord
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
Non-chordates are animals that do not possess a notochord, which is a flexible rod that provides support along the back of chordates (animals with a backbone). Non-chordates make up the majority of the animal kingdom and include groups such as arthropods (insects, spiders), mollusks (snails, clams), annelids (earthworms, leeches), and many others.
Animals with a segmented body plan belong to the phyla Arthropoda, Annelida, and Chordata. Segmentation involves the repetition of body units along the length of the organism, which can be seen in arthropods with their jointed limbs, annelids with their repeated segments, and chordates during embryonic development.
The zig-zag muscle sets in fish and chordates.

The notochord is the flexible supporting structure found only in chordates. It is a rod-like structure that runs along the length of the body, providing support and allowing for some degree of movement.
I believe that chordates have bilateral symmetry but I'm not sure. Try looking at: http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/bio%20102/Bio%20102%20lectures/Animal%20Diversity/Deuterostomes/deuterostomes.htm
Yes, the ventral nerve cord is a character found in chordates, not non-chordates. It is a defining feature of chordates, running along the belly side of the body and often involved in coordinating motor functions.
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
A notochord is a trait ancestral to all chordates. It is a flexible rod-like structure that provides support along the body axis and may persist in some chordates throughout their entire life, while in others it is replaced by the vertebral column.
It runs along the dorsal side of the body.
A row of long lots along a river or road is called a ribbon development. This type of development involves parcels of land that are long and narrow, with their long sides running parallel to the road or river.
The repetition of body parts along the length of an animal's body is termed segmentation. This characteristic is found in organisms like annelids, arthropods, and chordates during certain stages of development. Segmentation allows for specialization of body parts and greater flexibility in movement.
Non-chordates are animals that do not possess a notochord, which is a flexible rod that provides support along the back of chordates (animals with a backbone). Non-chordates make up the majority of the animal kingdom and include groups such as arthropods (insects, spiders), mollusks (snails, clams), annelids (earthworms, leeches), and many others.
