The Human Body: The Nervous System
The human Body is a very complex organism. It is composed of many different organs systems, which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important, the nervous system. The nervous system functions as the control center of the body, and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb, E.N. & Hoehn, K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help …show more content…
The first one is the central nervous system which includes the brain and the spinal cord. The nerves of these two structures are in control of body movement. The second division includes the rest of the nerves and ganglia that are not included in the central nervous system, which serve as communications relay and it’s known as the peripheral nervous system (Marieb, E.N. & Hoehn, K.). The existence of both divisions is very important because their function is necessary in order to maintain a homeostasis. The peripheral nervous pick up stimuli through receptors from the external environment. Stimuli is then sent to the brain for processing via afferent sensory neurons. Once the brain receives the information and processes it, it send a response via efferent sensory neurons. The response gets to effector muscles which can now react to the situation on the external environment. If one or more nerves in either one of the two divisions is damaged, the person’s body would not respond properly to the brain’s demands, putting the person’s life in danger. For this reason, illnesses that put the nervous system at risk of getting damaged need to be taken care of as soon as they are …show more content…
Most of these drugs have been proven to be efficient when tested in animal subjects. The drugs are capable of slowing down the progression of the disorder and making the symptoms less prevalent. The two most effective drugs used are miconazole and clobetasol. These had the ability of “promoting precocious myelination in organotypic cerebellar slice cultures, and in vivo in early postnatal mouse pups” (Najm, F.J. et al). In addition, these drugs have a major effect in two different components of the disease. Miconazole allows the increment of oligodendrocytes and makes remyelination more likely to occur while clobetasol targets the immune system directly as a strong immunosuppressant. Differently from medical drugs, other methods used to alleviate symptoms are therapy treatments. Physical therapy is commonly used, as it helps stimulate muscle tissue allowing it to maintain mobility. Although long terms effects are rarely reported, there are many reports stating that exercises helps decrease the amount of limitations that multiple sclerosis present in the patients (Doring , A. et.

    SPECIAL SENSES GENERAL PRESENTATION Overview of the Nervous System • Endocrine and nervous systems maintain internal coordination – Endocrine system: communicates by means of chemical messengers (hormones) secreted into to the blood – Nervous system: employs electrical and chemical means to send messages from cell to cell 12-2 Overview of the Nervous System • Nervous system carries out its task in three basic steps • Sense organs receive information about changes in the body and external environment, and transmit coded messages to the brain and spinal cord (CNS: central nervous system) • CNS processes this information, relates it to past experiences, and determines appropriate response • CNS issues commands to muscles and gland cells to carry out such a response 12-3 Overview of the Nervous System • Two major subdivisions of nervous system – Central nervous system (CNS) • Brain and spinal cord enclosed by cranium and vertebral column – Peripheral nervous system (PNS) • All the nervous system except the brain and spinal cord; composed of nerves and ganglia • Nerve—a bundle of nerve fibers (axons) wrapped in fibrous connective tissue • Ganglion—a knot-like swelling in a nerve where neuron cell bodies are concentrated 12-4 Overview of the Nervous System • Peripheral nervous system contains sensory and motor divisions each with somatic and visceral subdivisions – Sensory (afferent) division: carries signals from receptors to CNS • Somatic sensory division: carries signals from receptors in the skin, muscles, bones, and joints • Visceral sensory division: carries signals from the viscera (heart, lungs, stomach, and urinary bladder) 12-5 Overview of the Nervous System • Motor (efferent) division—carries signals from CNS to effectors (glands and muscles that carry out the body’s response) – Somatic motor division: carries signals to skeletal muscles • Output produces muscular contraction as well as somatic reflexes—involuntary muscle contractions –…

    The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body's external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent fibers); some nerves contain only sensory nerve fibers (afferent fibers); and some nerves contain both sensory and motor nerve fibers (mixed). All spinal nerves are mixed. Cranial nerves…

    Our knowledge of the human body has grown and psychology itself has become an expanding field of knowledge, various research and studies have been carried out on the brain. The most well-known of the brain cells are the neurons, the human brain contains around 10, billion neurons. Neurons are not like every other type of cell found in the human body, they do not usually reproduce themselves, in every other organ of the human body there is a continual turnover of cells, some very rapidly replace in hours. The function of the neuron is to transmit impulses from their origin to their destination i.e. to the muscle that controls movements of the legs and cardiac function. The nerve fibres of a neuron are not actually joined together but have a minute gap called synapse and this transmit from one neuron to another and again to the central nervous system which is the main communication system of the body it receives and interpret information from both inside and outside of the body. The nervous system has two main divisions:…

    The first system of the human body is the nervous system. The nervous system is made up of two parts: the central nervous system, which includes the brain and the spinal cord, and the peripheral nervous system, which consists of neurons found all over the body. A person’s brain is like a control room. It helps regulate all the other systems of the body by sending signals down the spinal cord and through the body nerves to all the other organs. In addition, the brain has different parts which specialize in processing thoughts, memories, feelings, dreams, speech, physical coordination, balance, hunger, and sleep. The fact that the nervous system is extremely complicated, without it, your systems in your body could not communicate.…

    The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body's ability to carry out complex function. Once a disruption occurs, one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network.…

    Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…
