The Nervous System: A Masterpiece of Human Physiology
The nervous system is one of the most intricate and fascinating systems in the human body, responsible for coordinating and controlling virtually every function, sensation, and movement we experience. From the simplest reflex actions to complex cognitive processes, the nervous system plays a pivotal role in our daily lives, making it a subject of immense interest and study in the field of biology and medicine. An Overview of the Nervous System At its core, the nervous system comprises two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that branch out from the CNS to the rest of the body.
