Question

What is the difference between a nerve cord and notochord?

Answer 1

Hint Chordates have two distinguishing features: the notochord and the nerve cord. The notochord and nerve cord are located in the dorsal region of the animal, from the neck to the tail. Nerve cord is a solid thread of nervous tissue, and the notochord is a skeletal rod.

Complete answer:
Chordates are known for their notochord and nerve cord. The notochord and nerve cord are located in the dorsal region of the animal, from the neck to the tail. A nerve cord can be a rigid strand of nerve tissue, while a notochord can be a skeletal rod.
The fundamental distinction between the notochord and the nerve cord is that the notochord involves the skeleton, whereas the nerve cord involves chordates' central nervous system. The notochord is a structure that connects the nerve cord to the central nervous system. The nerve cord is found beneath the notochord. The notochord provides locations for the skeletal muscles to connect. The body's functions are coordinated through the nerve cord.

Notochord	Nerve cord
The notochord is an embryonic midline structure found in all members of the Chordata phylum that provides the growing embryo with both mechanical and signalling inputs.	The term "nervous cord" can apply to a variety of things.
The notochord is a fundamental component of vertebrate development that emerges from the dorsal organiser.	Chordates' dorsal nerve cordInvertebrates have a ventral nerve cord.
Position:Between the nerve cord and the central nervous system is the notochord.	Position:The nerve cord is found beneath the notochord.
The notochord provides attachment points for skeletal muscles.	The body's functions are coordinated through the nerve cord.
Between the nerve cord and the central nervous system is the notochord.	The nerve cord is found beneath the notochord.

Note: Chordates are distinguished by their notochord and nerve cord. The notochord and nerve cord are both located in the dorsal region of the body, from the neck to the tail. Rod-like structures are found in both the notochord and the nerve cord.
