(CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves. N Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and 85 to 180 billion neurons in the human brain?!
