The Central Nervous System And Spinal Cord

19.The autonomic nervous system division of the PNS consists of nerves which control all of the involuntarymuscles, organs, glands, and sensory pathway nerves.

45.Cerebellum: the "little brain" at the rear of the brainstem; processes sensory input and coordinates movement output and balance.

Continuing on we as a class learned about the spinal cord, which is a column of nerves lining our back, as well as the central nervous system, which is the human body’s main processing unit. Chapter two focuses primarily on these two aspects of the body. The central nervous system is the brain and spinal cord, the brain, hindbrain, and midbrain are in charge of the senses. Hearing and sight for example are dealt with in the forebrain. The nervous system includes many different working pieces that control the body. Such as Dendrites; these are the hairs on the neurons. Ions have both negative and positive neurons which each has three, included with the soma in the cell body. Axon is the long tube of it, and the terminal button is the end of the tube.

The Peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.

The central nervous system is what connects the brain to the muscles of the body. When a patient has an injury to the spinal cord, movements in certain parts of the body will be affected based on the location of the injury. If the injury affects hand motion then many day to day tasks are affected. This literature review seeks to understand how an injury to the spinal cord impacts movement, and what has been done so far to help those affected by spinal cord injuries.

The Central Nervous System is the control center of the nervous system. Containing the brain and the spinal cord, the central nervous system interprets signals that are created by neurons through sensory inputs and prescribes them into motor outputs. Multiple

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.

The nervous system is associated to many neurological diseases including strokes, Alzheimer’s disease, Parkinson’s disease, sleep disorders, and spinal cord injuries. Spinal cord injuries arise to be extremely common, in fact, each year in the United States there are ten thousand new spinal cord injuries alone (Spinal Cord Injury). The spinal cord is an immensely fragile part of the body, it contains a bundle of nerve fibers that connect the brain to the rest of the body. Since the spinal cord is exceptionally fragile it has to be protected by something hard, like the vertebral column. The brain, spinal cord, and the vertebrae is considered the central nervous system, whereas, the peripheral nervous system is formed when the nerves that enter and exit the spinal cord (Boyce). When the spinal cord, brain, or vertebral column becomes damaged, the individual has a higher risk of developing paralysis. Since the nervous system contains all three parts of the nervous system, paralysis is diagnosed as a neurological injury.

The spinal cord in partnership with the brain sends information around the body by electrical signals. It informs the body exactly what it is the brain requires, the brain then interprets what the body is feeling. The spinal cord in conjunction with the brain makes up the CNS. A cylinder of nerve tissue which resembles a thick cream coloured rope about the thickness of the little finger with a length of approximately 38/45 centimetres stretches these distance to where it joins the medulla oblongata situated at the base of the brain and runs down the spinal cord to the level of the first lumbar vertebra, here it terminates into a bunch of nerves known as the cauda equina, known by this name due to its appearance of a horse tail. Here it

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 peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

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 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.

     The brain is aware of its surroundings, via input from the spinal cord and cranial nerves. Cranial nerves with sensory functions allow us to smell and see. Nerves with both motor and sensory functions are responsible for everything from tasting and chewing, to breathing and the heating of your heart. Many of the little things we take for granted are also made possible by cranial nerves.
