Nervous Network

This passage describes the nervous system, highlighting its two main components: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS, which includes the brain and spinal cord, acts as the control center for decision-making and communication. The PNS connects the CNS to the rest of the body, transmitting messages between the brain and various body parts. The passage also explains how sensory input from the environment, such as heat or sound, is processed by the nervous system.

Reading this passage helps students improve their comprehension by explaining how the nervous system functions as a whole. It introduces technical vocabulary like “central nervous system” and “sensory input,” helping students build their knowledge of biology. The passage encourages critical thinking, prompting readers to consider how sensory information affects their daily lives. Furthermore, it strengthens their ability to follow informational text with clear explanations of complex body systems.
