The Nervous System And Peripheral Nervous Systems

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 nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

In the nervous system there are two main parts that it can be broken down into. The central nervous system (CNS) and peripheral nervous system (PNS). The CNS controls the brain and spinal cord. The PNS’s main job is to connect the CNS to the brain and spinal cord to the rest of the body e.g. the organs so that they can communicate/ relay information to each other. How does this work?

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

The nervous system is made up of 2 main parts - the spinal cord and the brain. These two parts combine to make the central nervous system and the sensory and motor nerves which form the peripheral nervous system. Neurons process information in the form of electrical signals, namely nerve impulses, which travel along the axon. Charged ions are not able to enter plasma membranes which make neurons have a difference in ion concentration between the inside and the outside of a neuron. This prevents the passive diffusion of Potassium and Sodium ions from areas of high concentration to areas of low concentration. Proteins which act as ion channels and ion pumps are attached to plasma membranes. This allows the ions to be transported across

The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose

Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it works.

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 comprise of the CNS and peripheral nervous system. The brain and spinal cord make up the CNS, while the autonomic nervous system and somatic nervous system makes up the peripheral nervous system illustrated in figure 1 below.

Brain stem- initial portion of the brain that contains the medulla oblongata, pons, and midbrain

The central nervous system is composed of our spinal cord and brain which consistently controls our mind and behavior. The complexity of our brain is not entirely deciphered, but with extensive scientific research it can be concluded that each specific section has its own specialized function. In reference to eating pizza, socializing, and playing a game of cards, it can be deduced that our central nervous system is always critically analyzing data using our Broca’s area for speech, hippocampus for memories, hypothalamus controlling internal body, and occipital lobe organizing visual stimuli.

The central nervous system (CNS) is one of the two major parts of the nervous system. The CNS includes the brain, brain stem, and spinal cord, which together include the body's main control and data centre. Together with the peripheral nervous system (PNS), the CNS performs important functions.

The nervous system is a complex network of nerves and cells that transmit signals and carry messages between different parts of the body (Zimmermann, 2018). It is the body’s electrical wiring. The nervous system has two components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is the part of the nervous system that consists of the brain and spinal cord (Myers & Dewall, 2014). The PNS is the sensory and motor neurons that connect the CNS to the rest of the body (Myers & Dewall, 2014). Essentially the CNS makes the decisions and the PNS gathers information from the rest of the body, it then transmits the CNS

The peripheral nervous systemcontrols all voluntary amd involutary muscles and glands. Peripheral nervous system contains all your nerves amd nerve bundles excluding the brain and spinal cord. The Central spinal cord. The CNS receives sensory infpormation from the nervous system and controls the body's responses. The diffrence between peripheral and central nervous system are th CNS, collections of neurons are called nuclei. In the PNS, collection of neurons are called ganglia. another diffrence would be the CNS, collections of axons are called tracts. In the PNS, collections of axons are called nerves.

-The CNS is composed of the brain and the spinal cord. This system is responsible for the sensory information and responding accordingly. The spinal cord sends signals between the brain and the rest of the body and controls simple musculoskeletal reflexes. This isn’t using input from the brain. The brain is responsible for most sensory information and coordinating body function, both consciously and unconsciously. Also one portion of the CNS we may forget at times is the retina. The retina is formed as an out pocketing of the diencephalon during development. This is known as the optic vesicle.
