Central nervous system composed of?

Explanation: The Central Nervous System (CNS) consists of only two main parts: the brain and the spinal cord. The CNS is responsible for receiving, processing, and coordinating information throughout the body.

Why the other options are incorrect:

• Cerebrum, Thalamus and Hypothalamus: These are important parts of the brain but do not represent the complete Central Nervous System.
• Brain, Spinal Cord and Peripheral Nerves: Peripheral nerves belong to the Peripheral Nervous System (PNS), not the CNS.
• All of these: Incorrect because only the brain and spinal cord make up the Central Nervous System.
