Verified step by step guidance

1. Understand that the human nervous system is broadly divided into two main parts based on structure and function.
2. Identify the Central Nervous System (CNS), which consists of the brain and spinal cord, responsible for processing information and controlling most functions of the body and mind.
3. Recognize the Peripheral Nervous System (PNS), which includes all the nerves outside the CNS and connects the CNS to limbs and organs.
4. Note that the Somatic and Autonomic nervous systems are subdivisions of the Peripheral Nervous System, not the main divisions themselves.
5. Conclude that the two main divisions of the human nervous system are the Central Nervous System and the Peripheral Nervous System.
