The Autonomic Nervous Sub-system has sympathetic and which type of nerves?

• A. Central
• B. Parasympathetic
• C. Motor
• D. Peripheral

Answer: (B)

The correct choice is parasympathetic because the autonomic nervous system (ANS) consists of two main divisions: the sympathetic and the parasympathetic nervous systems. The sympathetic nervous system is primarily responsible for the body's 'fight or flight' responses, which prepare the body for stressful situations by increasing heart rate, dilating airways, and inhibiting digestive functions, among other actions. In contrast, the parasympathetic nervous system is associated with 'rest and digest' functions, promoting activities that occur during restful states, such as stimulating digestion and lowering heart rate. Understanding the parasympathetic nervous system is crucial for recognizing how different substances and drugs can affect the two branches of the ANS. For instance, certain drugs may enhance or inhibit functions associated with either the sympathetic or parasympathetic systems, leading to varied physiological responses that are important for drug recognition. The other options do not fit this context. The term central refers to the central nervous system, which consists of the brain and spinal cord, and is distinct from the peripheral autonomic pathways. Motor relates to voluntary movement, which is more about somatic nervous control, while peripheral generally refers to the nerves outside of the central nervous system, not specifically linked to the autonomic
