Concept:The central nervous system (CNS) is the control centre of the body, made of the brain and the spinal cord.
Explanation:The CNS consists of two main parts.
The brain is the centre for thought, emotion, movement, and learning.
The spinal cord connects the brain to the rest of the body and relays messages between them.
Together, they process information and coordinate body activities.
The somatic system is part of the peripheral nervous system, not the CNS.
Therefore, the correct option is the one that lists both the brain and the spinal cord.
Answer:B. brain and spinal cord
