Which system controls consciousness and mental activities?

  1. Automatic Nervous System (ANS)

  2. Central Nervous System (CNS)

  3. Peripheral Nervous System (PNS)

  4. Sensory Nerves

The correct answer is: Automatic Nervous System (ANS)

The correct answer is the Automatic Nervous System (ANS). The CNS consists of the brain and spinal cord, which are responsible for processing sensory information and controlling bodily functions. The PNS, on the other hand, connects the CNS to the limbs and organs, transmitting sensory information and motor commands. Sensory nerves are a part of the PNS and transmit sensory information to the CNS. However, when it comes to controlling consciousness and mental activities, the ANS plays a crucial role in regulating involuntary processes such as heart rate, digestion, and respiratory rate, thereby influencing our state of consciousness.
