Systema nervosum is the Latin pronunciation for human Nervous System. Nervous System of the body is comprised of Brain, Spinal Cord, Sensory Organs and all of the Nerves that connect these organs to the rest of the body. All these organs function together for the control of body and communication of its parts. Central Nervous System is the control center of the body and is made of Brain and Spinal Cord. This part is responsible for information evaluation and making the decisions afterwards. Monitoring the outside conditions and sending the relative information to Central Nervous System (CNS), is carried out by sensory nerves and sense organs of Peripheral Nervous System (PNS). To regulate the functions of the Glands, Organs and Muscles Efferent Nerves of the PNS carry signals from the control centers.
