Question

list the major functional divisions of the nervous system.

Explanation:

• Central Nervous System (CNS): Composed of the brain and spinal cord. It is the control center, processing sensory information and coordinating motor responses.
• Peripheral Nervous System (PNS): Connects the CNS to the rest of the body.
• Somatic Nervous System: Controls voluntary movements (e.g., moving limbs).
• Autonomic Nervous System: Manages involuntary functions (e.g., heart rate, digestion).
• Sympathetic Nervous System: Activates the “fight - or - flight” response.
• Parasympathetic Nervous System: Promotes the “rest - and - digest” state.

Answer:

The major functional divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS can be further divided into the somatic nervous system and the autonomic nervous system. The autonomic nervous system has two divisions: the sympathetic and the parasympathetic nervous systems.
