Question

Give one point of difference between the notochord and nerve cord.

Answer 1

Hint: Notochord indicates a longitudinal flexible rod of chordates that substructally hold up the body. Nerve cord refers to the main cord of nerve fibers which develops into the brain and the medulla spinalis of vertebrates.

Complete answer:
Notochord and nerve cord are two usual properties of chordates. Both notochord and nerve cord are from the neck to the tail within the dorsal part of the body. Notochord may be a skeletal rod, and a nerve cord may be a hard strand of nerve tissue. The main difference between notochord and nerve cord is that notochord involves the skeleton whereas nerve cord involves the central nervous system of chordates. Notochord occurs between the nerve cord and therefore the central nervous system. Nerve cord occurs below the notochord. Notochord gives sites for the joining of the skeletal muscles. Nerve cord coordinates the functions of the body.

Additional Information: Other differences between notochord and nerve cord are-

Notochord	Nerve cord
The notochord is a rod-like structure, which is formed from vacuolated cells.	The nerve cord is a chain of ganglia.
Notochord originates from the mesoderm.	Nerve cord originates from the ectoderm.
Notochord occurs in chordates.	Nerve cord occurs in both invertebrates and vertebrates.
Notochord provides structural support and the sites for the attachment of skeletal muscles.	The nerve cord arranges nerve impulses that come from the peripheral nervous system.
Notochord forms the axial skeleton of vertebrates.	The nerve cord shapes huge parts of the central nervous system which are the brain and the spinal cord.

Note: Both notochord and nerve cord are characteristic features of chordates. Notochord and nerve cord both are situated from neck to the tail in the dorsal part of the body. Both notochord and nerve cord are rod-like structures.
