The Nervous System ( Cns ) Essay - 2025 Words

The systems inside our body interact with each other in order for us to adapt to the changes inside and outside of our body. The human body is able to adjust and control the different organs, cells, and tissues by contacting the brain with electrical impulses which then goes onto adjust and reply to the signals to maintain the proper function of the body. Similarly, The nervous system arranges and monitors the actions that occur throughout the entire human body. The nervous system consists of the spinal cord and a range of neurons working together. It sends, receives, and processes information from all over our body. The nervous system itself divides into two sections: The Peripheral Nervous System (PNS) and The Central Nervous System (CNS). The Central nervous system includes the nerves of two main organs: the Brain and the Spinal cord. The Central nervous system and the Peripheral nervous system cooperate with each other even though they are two different parts of the nervous system assigned with different jobs. The Peripheral Nervous System sends information to the Central nervous system with the help of neurons known as the relay, motor and sensory neurons which then arranges the information and sends it back to the Peripheral Nervous System which then takes action on the problem. However, TheShow MoreRelatedThe Nervous System ( Cns )2228 Words   |  9 PagesIntroduction The nervous system coordinates voluntary and involuntary actions of animal bodies and is in charge of transmitting signal from one part of the body to another part. It is divided into two main systems, the Central Nervous System (CNS) that contains the brain and the spinal cord, and the Peripheral Nervous System (PNS) that includes mostly all nerves connecting the CNS to every part of the body (Martini et al., 2005). The entire nervous system relies on the good functioning of specializedRead MoreThe Nervous System ( Cns )2196 Words   |  9 Pages)The nervous system is a complex system our body uses to make decisions and perform actions. It is made up of cells called neurons and special cells called glial cells (or neuroglia). Neurons produce responses by generating action potentials. Action potentials are formed when graded potentials are summated at the initial segment (integrating center) of a neuron cell body. The action potential then propogates through the axon. The nervous sy stem has two main branches: the Central Nervous System, andRead MoreThe Nervous Systems ( Cns ) And The Peripheral Nervous System1784 Words   |  8 PagesThe nervous system is the part of the human body in charge of coordinating the reception of external stimuli and the response the body gives to them. It is equipped with sense organs called receptors, which are in charge of transforming the stimuli’s energy into nerve impulses [1]. To emit an external response, the nervous system uses effectors that can be either muscles or glands. We can divide the nervous system into two separate systems: the central nervous system (CNS) and the peripheral nervousRead MoreThe Central Nervous System Cns802 Words   |  4 Pagesmembrane potential is excited, the arrival of an action potential at the synaptic knob allows the neurotransmitters released into synaptic cleft to trigger an action potential in the postsynaptic neuron (McCance Huether, 2014). The central nervous system CNS is the main control center of the body that receives sensory input, organizes and synthesizes it then provides instructions for motor output to the rest of the body. It constitute of the brain and spinal cord. The brain consist of the cerebrumRead MoreThe Central Nervous System ( Cns ) Development1575 Words   |  7 PagesIntroduction Central nervous system (CNS) development is complex, as genetic and environmental factors influence rapidly occurring processes throughout prenatal life. During CNS development, phylogenetically primordial regions of the brain develop first, followed by more complex structures. When this procedure is disrupted, teratogenic outcomes are often observed, leading to serious mental or motor dysfunctions if not fetal death (Martin and Dombrowski, 2008). Thus the prenatal CNS is vulnerable to environmentalRead MoreMy Central Nervous System ( Cns )2557 Words   |  11 Pagesmake up the central nervous system (CNS), with the brain coordinating higher-level functions and the spinal cord relaying information from and to the peripheral nervous system (PNS). The CNS is contained within the dorsal cavity, with the brain protected by the skull and the spinal cord protected by the vertebrae. Despite this, injuries to the CNS are a global health problem because of the inability of central neurons to regenerate, unlike peripheral neurons. Injury to the CNS is initiated by mechanicalRead MoreEpilepsy Is A Central Nervous System Disorder ( Cns )1112 Words   |  5 PagesIntroduction Epilepsy is a central nervous system disorder(CNS) causing recurrent seizures and can only be defined when there is at least one epileptic seizure.[1][2] John Hughlings Jackson, a notable British neurologist proposed that epilepsy is an occasional, an excessive and a disorderly discharge of nervous tissue. About 65 million people(1% of the human population) in the world have epilepsy and the cases account for 80% in developing countries.

Glioma tumors are a type of brain and spine tumor that grow rapidly, and usually cause death within a year. Methods of treating glioma tumors with surgery, radiation, and chemotherapy have been generally unsuccessful (Ellert-Miklaszewska et al. 2003). Thus, the pursuit for a more effective treatment is required for gliomas. This experiment examined two main pathways involvedRead MoreCaffeine Is A Central Nervous System ( Cns ) Stimulant828 Words   |  4 PagesWhat is caffeine? Caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks and energy drinks enjoy great popularity: caffeine is the world’s most widely consumed psychoactive substance. In North America, 90% of adults consume caffeine daily. [1] Many natural sources of caffeine also contain widely varying mixtures of other xanthine alkaloids, including theRead MoreParkinson s Disease ( Cns ) And The Peripheral Nervous System999 Words   |  4 Pagesareas that produce the neurotransmitter dopamine† (Fischer, 1999). It affects the nervous system, more specifically it affects the nerve cells in your brain that secrete dopamine. Dopamine is a chemical that is responsible for the movement and coordination of the musculoskeletal system. The nervous system is composed of two separate systems: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord while the PNS consists of the nerves that are
