Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.
Our body is like a computer, our brain is the part of the computer that does all of the thinking for you. The PNS is the part of the computer that delivers messages to the body. If we are hot it sends our body a message telling it to cool us down (Brain Facts, 2012). We are filled with nerves throughout our body that send signals to the nerves in the PNS to control our internal organs and make sure that they work properly.
Nerve cells are made up of things called neurons, the cell body of the neuron has a long tinny axon that is covered by something called a myelin sheath, the axons are what pass the information from neuron to neuron and other cells in the body. The axons have a cover to protect them called myelin, this is what allows the brain and spinal cord to communicate with each other (Lindhom, 2014).

The thoracic section controls the chest, and the lumbar and sacral section controls the legs. The autonomic nervous system is made up of neurons that connect the CNS with our internal organs; there are two parts to the autonomic nervous system. The sympathetic nervous system rallies energy the things that the body needs during times of immense stress or even arousal. The parasympathetic nervous system helps us to save energy while we are in a relaxed state such as sleep (Brain Facts,
The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.
The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.
The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and
The central nervous system and the peripheral nervous system is the 2 main systems. The central nervous system is made up of the spinal cord and brain which is in the dorsal body cavity. It is the integrating and control center of the nervous system. Also the CNS helps with sensory input, dictates motor outputs based on reflexes and lastly past and current experiences.
The CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic
The nervous system (NS)consists of the central nervous system (CNS) and peripheral nervous (PNS.) It is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The NS integrate all physical, emotional, and intellectual activities. These two structures
The PNS consists of nerves and ganglia, which takes information and send this to the external stimuli. Meanwhile, our CNS consists of the brain and spinal cord that processes information. When processing this information in the CNS, the functions orders come from PNS sending back to the CNS to the correct body function or organ. Our central nervous system is an involuntary action, while our PNS is a voluntary action. Examples of our PNS can range from sitting down, picking an item up,
The components of the nervous system that are involved in physical sensation are Central Nervous system and Peripheral Nervous System. “The Central Nervous System’s role is to integrate, process, and coordinate sensory and motor commands” (Bartholomew). CNS controls only the spinal cord and the brain. The PNS controls the nervous system outside the spinal cord. The function of PNS is to send “sensory division to the central nervous system to be process” (Bartholomew).
The central nervous system is mainly the brain and spinal cord. These two have a very specific protective covering to build up by other soft tissues. The brain is dividing into forebrain, mid brain, and the hind brain. Most of the functional mapping for the muscular movements and the sensory approach, as well as the executive functions, is delivering throughout the fore brain into the discrete regions. The mid brain creates a part of the brainstem, which is basic keeping that person alive. The hind brain is involved in the formation of the head which is necessary to maintaining balance of the body. The spinal cord is a barred shaped of the nerve that connects to the brain. The spinal cord nerves transmit information from the body organs and
The central nervous system controls most functions of the body and mind. The information obtained from the peripheral
The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.
The system is made up of many organs that are responsible for numerous and separate functions. The nervous system is divided into two major functions namely the central nervous system (CNS) which has the brain and spinal cord; and the peripheral nervous system (PNS) which is outside the brain and spinal cord function e.g. nerves. The nervous system is the responsible for transporting information around us and also formulating feedback responses to that information. Therefore, sensation is a major function of the nervous system through which information is received from the environment via receptors known as stimulus. These receptors include but not limited to taste, smell, sight, touch, and hearing. Another function of the nervous system is generating responses to the stimuli from the sensory receptors. Responses are either voluntary or involuntary. Finally the final function of the central nervous system is integration, that is, stimuli received by the sensory structures is conveyed to the nervous system where the information is processed. Stimuli keeps track of ‘history’ of other stimuli and new stimuli is compared before a definite response is
The nervous system of the body is the communication and control network it comprises of the central nervous system (CNS), peripheral nervous system (PNS) and the autonomic nervous system (ANS).The brain and the spinal cord comprise to form the CNS, this is the body’s main control centre. The PNS is a complex network of nerves branching across the whole body, 12 pairs of cranial nerves originate from the brain and 31 pairs of spinal nerves originate from the spinal cord. These nerves transmit information between the body and the brain via nerve impulses. The ANS shares nerve structures with both the CNS and PNS, it functions automatically with no conscious awareness to control the body’s basic functions like heart rate. In the PNS there are two divisions; afferent and efferent. The afferent division controls signals sent to the brain and the efferent division controls message from the brain to the body. Sensory inputs travel via the afferent division to signal the brain for processing, co-ordination and interpretation. The brain makes a suitable decision to the signal sent and
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
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
