Aristotle once said, “The whole is greater than the sum of its parts.” However, the validity of this statement has been argued for centuries. How is one to measure each part and compare that sum to the sum of the whole? It simply can’t be done. To resolve this problem, Kurt Koffka offered, “It is more correct to say that the whole is something else than the sum of its parts because summing up is a meaningless procedure, whereas the whole-part relationship is meaningful.” This revised concept can actually be applied to the human body because its internal balance is due to fine-tuning on behalf of the different systems that work within it. If one system were to fail, the rest would soon follow, resulting in the destruction of the body. Therefore, the systems in the human body interact to help it maintain homeostasis, which affects the functioning of the body as a single unit.
Perhaps the most important system in the body is the nervous system. It functions as a network in which communication and regulation occur throughout the body. It is broken down into two parts; the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain, which is the control center of the system, and the spinal cord. The PNS, on the other hand, consists of sensory and motor neurons that connect the CNS to the rest of the body. The PNS can be further broken down into the somatic nervous system, which controls the body’s skeletal muscles, and the autonomic…
