The Ultimate Central Nervous System Quiz

Which part of the nervous system is primarily composed of the brain and spinal cord?

Which animals have a true brain?

What is the function of the meninges in vertebrates?

Which animals have a central nervous system that is radically distinct from all other animals?

What is the structure that may have an enlarged section at the rostral end in the central nervous system?

Central Nervous System

The central nervous system (CNS) in vertebrates comprises the brain and spinal cord.

Brain

A true brain is a feature found exclusively in animals within the kingdom Animalia.
All animals belonging to the Phylum Chordata possess a true brain.

Meninges

The meninges are protective membranes that surround the brain and spinal cord in vertebrates.
The meninges are responsible for providing protection, support, and nutrient supply to the central nervous system.

Distinct Central Nervous System

Cnidarians are a phylum of animals that possess a central nervous system distinct from all other animals.
The nervous system in cnidarians is characterized by a nerve net rather than a centralized brain.

Enlarged Rostral End

The brain is typically located at the rostral end (head) of the central nervous system.
In some animals, the rostral end of the central nervous system may show an enlargement, forming a brain with distinct regions.
