Question

question 22 which of the following is true about the autonomic nervous system?
∘ it is made up of the brain and spinal cord.
∘ it plays the primary role in sensory perception.
∘ it takes messages from the body’s internal organs to the central nervous system.
∘ it conveys information from the central nervous system to the skin and muscles.

Explanation:

1. Analyze Option 1: The brain and spinal cord are part of the central nervous system (CNS), not the autonomic nervous system (ANS). So this option is incorrect.
2. Analyze Option 2: Sensory perception is mainly handled by the sensory neurons and the CNS, not the ANS. The ANS is more about involuntary functions of internal organs. So this option is incorrect.
3. Analyze Option 3: The autonomic nervous system is responsible for carrying signals from internal organs (like heart, lungs, stomach) to the CNS and also sending signals from CNS to these organs to regulate involuntary functions. So this statement is true.
4. Analyze Option 4: The somatic nervous system conveys information from CNS to skin and muscles (voluntary movements), while the ANS is for internal organs. So this option is incorrect.

Answer:

The correct option is: It takes messages from the body’s internal organs to the central nervous system.
