Verified step by step guidance

Understand the context: The question is asking about a structure found in chordates, which are animals that have a notochord at some stage of their development.

Define the term 'notochord': The notochord is a flexible, rod-like structure that provides support. It is located along the dorsal (back) side of the organism.

Differentiate between the options: The spinal cord is part of the nervous system, the vertebral column is a series of bones (vertebrae) that protect the spinal cord, and cartilage is a type of connective tissue.

Identify the correct answer: The notochord is distinct from the spinal cord, vertebral column, and cartilage, as it is specifically a flexible rod-like structure found in chordates.

Conclude with the correct term: The term for the flexible rod-like tissue that extends along the dorsal side of a chordate is the 'notochord'.
