The Brain and Nervous System Once messages leave the central nervous system, they are carried by the peripheral nervous system. The peripheral system includes the cranial nerves (nerves branching from the brain) and the spinal nerves (nerves branching from the spinal cord).These nerves convey sensory messages from receptor cells in the body to the central nervous system.he central nervous system consists of the brain and the spinal cord. The brain lies within the skull and governs body functions by sending and receiving messages through the spinal cord.

Brain The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 15–33 billion neurons,[1] each connected by synapses to several thousand other neurons.

Drugs and the Brain The brain is a communications center consisting of billions of neurons, or nerve cells. Networks of neurons pass messages back and forth among different structures within the brain, the spinal cord, and nerves in the rest of the body (the peripheral nervous system).These nerve networks coordinate and regulate everything we feel, think, and do. 1  Neuron to Neuron.2  Each nerve cell in the brain sends and receives messages in the form of electrical and chemical signals. 3  Once a cell receives and processes a message, it sends it on to other neurons.etworks of neurons pass messages back and forth among different structures within the brain, the spinal cord, and nerves in the rest of the body (the peripheral nervous system).

Central Nervous System Function The two main organs of the CNS are the brain and spinal cord. Photo Credit: Credit: Dream Designs/ FreeDigitalPhotos.net. The central nervous system (CNS) is the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain processes and interprets sensory information sent from the spinal cord. Both the brain and spinal cord are protected by three layers of connective tissue called the meninges. Within the central nervous system is a system of hollow cavities called ventricles.

Parts of the Nervous System Parts of the Nervous System. The center of the nervous system is the brain. The brain takes in what your eyes see and ears hear, and if you decide that you want to move around, your brain tells your muscles to do it. Your brain makes your muscles move by sending tiny electrical signals to them through your nerves. Peripheral nervous system (PNS): a part of the nervous system which includes all the nerves outside of the brain and spinal cord. 2  Sympathetic nervous system: The part of your nervous system that unconsciously controls your organs and glands when you're excited or frightened.

What are the parts of the nervous system? The brain sends messages through the spinal cord and nerves of the peripheral nervous system to control the movement of the muscles and the function of internal organs. The basic working unit of the nervous system is a cell called a neuron. The human brain contains about 100 billion neurons.

Functions of the Nervous System Neurons are specialized cells of the nervous system that transmit signals throughout the body. So, now that Timmy's neurons have gathered information from the environment, relayed this information to his brain, processed the information into a visual and categorized what he sees, Timmy now has a decision to make.

The Brain and Nervous System The closer an animal is to humans on the evolutionary tree—think chimpanzees and gorillas, the more developed is this portion of their brain. The Peripheral Nervous System. In addition to the central nervous system (the brain and spinal cord) there is also a complex network of nerves that travel to every part of the body. This is called the peripheral nervous system (PNS) and it carries the signals necessary for the body to survive (see Figure 7).

How Your Brain Works These fundamental members of the nervous system also vary with respect to their functions. Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system. Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body. Interneurons connect various neurons within the brain and spinal cord.

Why does your bodies need the nervous system? The nervous system and the circulatory system work together in that  the brain sends signals to the heart that cause it to pump. The  circulatory system works with the excre … tory system because waste  materials are transported by blood to the organs of the excretory  system. The nervous system works in your body by sending signals to other body systems for example the brain sends a signal to the circulatory system that tells the heart to pum … p blood. 36 people found this useful.

Brain In invertebrates, the enlarged and specialized anterior ganglion of the central nervous system is often referred to as a brain, although not all scientists regard it as a true brain. The brain receives and processes sensory information, initiates and controls movement, and executes cognitive (thought) processes.he brain receives most of its input from, and sends most of it output to, the spinal cord, which merges with the brainstem at the base of the brain. The twelve cranial nerves provide input and output pathways to and from the structures in the head.

How does the Nervous System Work? The nervous system is the most complex system in the human body. It is surrounded by a network of more than hundred billion neurons, assisted by many glial cells.Like the processor in a computer, this system works as a data receiving, processing and transferring center for the human body.he nervous system permits fast and specific communication between the brain and broadly spaced parts of the body. This communication process is done by the action of billions of dedicated nerve cells.

Nervous System The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made.

The Nervous System The CNS is made of the brain and spinal cord. The cranial nerves, spinal nerves and ganglia make up the PNS. The cranial nerves connect to the brain. The cranial and spinal nerves contain the axons (fibres) of sensory and motor nerve cells. Nerve cells areas are also known as neurons. Neurons are the basic unit of the nervous system. They carry information or impulses as electrical signals from one place to another in the body.
