Notochord :
It is a solid ensheathed dorsal rod of large vacuolated cells.
It occurs in chordates.
It provides support and point of attachment to muscles.
In vertebrates, it forms the axial skeleton.
Nerve cord :
It is a bundle of nerve fibres with chains of ganglia, generally running ventrally
It occurs m invertebrates.
It gives rise to peripheral nerves.
It forms a major part of nervous system

(4) It occurs between the nerve cord and the central nervous system.
(5) It is present in Chordates.
☆Nerve Chord:-
(1) It is solid strand of nervous tissue.
(2) It belongs to the central nervous system.
(3) It coordinates the functions of the body.
