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 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

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

What is the Nervous System? The nervous system is an organ system that is a network of nerves and fibers that nerve impulses between different parts of the body‚ and is responsible for sending‚ receiving and processing. All the organs and functions rely upon these nerve impulses to function. It’s an example of the body’s master control unit. The nervous system is the control and communication system of your body. its job is to send and receive messages to your body. the nervous system controls

The central nervous system (CNS) is that portion of the vertebrae nervous system that is composed of the brain and spinal cord. Together with the peripheral nervous system (PNS)‚ the other major portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most

Include in your outline the major distinctions among these systems. Human Nervous System – Overview The human nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response The nervous system has two distinct parts

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
