Psychology The Nervous System The nervous system is divided into two main areas‚ the peripheral nervous system and the central nervous system. The central nervous system controls the brain and spinal cord. The average human brain weighs approximately 3 pounds and contains approximately 100 billion neurons‚ as well as trillions of “support cells” called glia. The spinal cord weights approximately 35-40 grams and is around 43 cm long in adult woman and 45 cm long in adult men. The frontal

The nervous system is one of the most important systems in the body. The nervous system helps to keep the human body in balance. There are several important parts of the nervous system; the brain‚ spinal cord‚ and nerves. Each part of the nervous system has different jobs. There are two main parts of the nervous system peripheral and central. The peripheral nervous system is a collection of peripheral nerves‚ ganglia and specialized sensory structures that‚ as a unit‚ carries sensory and motor information

The divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS is made of two parts the brain and the spinal cord. The PNS is made up the Somatic nervous system and the automatic system. The somatic nervous contains the peripheral nerve fibers that deliver sensory information to the CNS and motor nerve fibers that go to the skeletal muscle. The central nervous system sends messages from the brain to the rest of the body. (Divisions of The

The job of the central nervous system is to process and send information to the peripheral nervous system. The nervous system consists of the brain‚ spinal cord and a complex network of neurons. The central nervous system is responsible for receiving‚ sending and interpreting information from the whole body. The nervous system also monitors and coordinates internal organ functions and responds to external changes as they occur. The two main organs of the central nervous system are the brain and spinal

Central Nervous System In the movie the Wizard of Oz‚ the Scarecrow desperately wanted a brain. He opened his lips‚ blinked his eyes‚ shook his head and said‚ “I haven’t got a brain‚ I’ve only got straw.” The reason for the emphasizing of his actions is because without a brain‚ those functions are not possible. The brain is the center of the entire body. It controls what we do and how we do it. The brain is the center of the central nervous system along with the spleen. It consists of 100
