Focal Nervous System Paper

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.

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

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 nervous system is responsible for muscle movement. The nervous system consists of central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is constitute of the brain and the spinal cord, and PNS is a network of nerves that runs throughout the body. The brain sends electrical signals to the CNS, and they are disbursed the PNS to produce body movement (Acrobatiq, 2014). Then, these signals travel back from the PNS to CNS to coordinate the next course of action of the body (Acrobatiq, 2014). The motor cortex section in the cerebrum sends messages to the muscles to coordinate accurate movement. Also, its control balance posture during the exercise and movement. The muscles instructed by the impulses from the cerebrum move in the given direction. They relax and contract according to the message relayed by the motor neurons.

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 somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin. In the nervous system, nerve cells send messages electrochemically: this means that chemicals cause an electrical impulse from one cell to another.The central nervous system or the CNS contains the brain and the spinal cord. All together, the brain and the spinal cord serve the nervous system's command station. When the sensory input reaches the CNS, the spinal cord and the brain figure outs what it exactly means. Everything else but the CNS it is known as the peripheral nervous system. The peripheral nervous system or PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. The peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the CNS as quickly as possible. The pathway that the communication within the nervous system would follow from a receptor to an effector would start with a stimulus and then the receptors that are located all over the body, but there are some types of receptors that are in specific areas of the body, like taste receptors in the mouth.From there, sensory neurons then transmit information from the sensory receptors to the central nervous system (CNS), like the brain and spinal cord. This is happens because peripheral nerves connect to the spinal cord via the network of nerves within the nervous system. Information so received by the CNS is further transmitted by relay neurones within the CNS. Following either simple reflex arc response, or processing by the brain, neural 'instructions' may be sent via a motor neuron to an effector (usually a muscle or gland). In this way, the effector is instructed to take action. Whatever the consequent action, this has occurred due to

The anatomy of the nervous system is called neuroanatomy. Which consist of two areas having special construction and abilities. This is basic formation of the nervous system which controls the way we think and act as a source of inside instructions on direction to our surroundings as human beings. The primary nervous system is developed from a basic hollow stem and that stem grows in size and disburses into other areas which would be your head with backbone and the nerves with sensors throughout the body. The head is made up of two cerebral hemispheres protected by a hard shell which is surrounded with a fluid that keeps your blood stream separated from it. The head and backbone is the

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 nerves system by definition is the system of nerves and nerve centers in an animal or human, including the brain, spinal cord, nerves, and ganglia. The nervous system is an intricate collection of nerves that sends signals between parts of the body, basically the body’s version of electrical wiring. Structurally, the nervous system is split into two components: the central nervous system and the peripheral nervous system. The Central Nervous System consists of the brain and spinal cord while the Peripheral is made up of the cranial nerves, spinal nerves, plexuses and peripheral nerves. Functionally, the nervous system has two main subdivisions: the somatic(voluntary); and the autonomic(involuntary). The autonomic nervous system regulates

The central nervous system, or CNS, consists of the brain and spinal cord. The CNS is responsible for accepting information from the rest of the body through the peripheral nervous system, and responding by sending signals back out into the body. It is essential that the CNS work properly for one to function properly in day to day life. However, there are circumstances in which it is necessary for the CNS to be suppressed or excited for the wellbeing of a patient. The CNS is affected by varying types of medications including but not limited to: anesthetics, anticonvulsants,

The nervous system is figuratively a command center of various organisms, including humans, in which its primary role is to receive and send messages. These messages are carried by nerve cells, known as neurons. The two major components of the system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) (Eunice Kenedy Shiver National Institute of Child Health and Human Development 2013). Previous educational research demonstrate that the CNS contains the brain and the spinal cord. The brain, one of the most important organ, is also made up of many parts, where each part has its own roles, such as the control over awareness, movements, sensations, thoughts, speech, and memory. For instance, the occipital lobe, which is

The nervous system is an especially complex and highly specialized network of cells that are responsible for controlling all voluntary and involuntary actions in the human body. It is also responsible for the communication between the many different parts of the body. The nervous system is divided into many subsystems, but structurally, it is comprised of the central nervous system (CNS), and the peripheral nervous system (PNS). Other functional subsystems include the enteric nervous system (ENS), the somatic nervous system (SNS), and the autonomic nervous system (ANS), which can be further divided into two components; the sympathetic and parasympathetic nervous systems.

The organs of the nervous system can be divided into two groups. One group consisting of the brain and spinal cord, forms the central nervous system. The other, composed of the nerves ( bundles and axons) that connect the central nervous system to other body parts, is called the peripheral nervous system. Together, these systems provide three general function: sensory, integrative, and motor. The sensory function of the nervous system derives from sensory receptors at the ends of peripheral neurons. These receptors gather information by detecting changes inside and outside the body. Sensory receptors monitor external environmental factors, such as light and sound intensities, and conditions of the body’s internal environment, such as

Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the

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.
