The nervous system is made up of two systems that work together to help the body function. One of the systems is the Central Nervous System (CNS) which consists of the spinal cord and the brain. The other system is the Peripheral Nervous System (PNS) which is made up the nerves that connect to the rest of the body. Working together they both contribute to the wonder known as the nervous system, but how? (Better Health Channel, 2014).

As said before, the Nervous system is made up of two systems, CNS and PNS. However, Neurons are microscopic cells that play a massive part in the workings of the Nervous system. What sets apart Neurons form other cells is that they can transmit electrochemical signals when stimulated. Neurons naturally have a small negative charge but when stimulated they produce enough electrical energy to create a reaction in these systems (Better Health Channel, 2014).

If you have ever hurt a part of your body, say your leg, you would know that sometimes it feels like the pain is shooting up the entire leg. This is due to the Neurons being stimulated when the leg is hurt which causes a reaction in the nerves. I bet your wondering how the pain travels all the way up you leg. This is due to synapses (Better Health Channel, 2014).

The Neurons travel through your body through carrying the electrochemical signals in them when they reach a synapse the neurotransmitters project the said electrochemical energy into another Neuron that travels through another part of the body. Once the signals have travelled all the way to the brain the effector cells and organs (the cells/organs the carry out the instructions of the Nervous system) try and pull the body away from the stimulus (Better Health Channel,

Foundations of Psychology

...intertwined and attempt to answer basic questions of how the body and mind work together. The Four Major Psychological Perspectives The Psychodynamic Perspective The psychodynamic perspective was developed in the late nineteenth century by Sigmund Freud. He concluded that psychodynamic perspective has three key premises: 1. “People’s actions are determined by the way thoughts, feelings, and wishes are connected in their minds. 2. Many of these mental events occur outside of conscious awareness. 3. These mental processes may conflict with one another, leading to compromises among competing motives.” (Kowalski & Westen, 2011) The Psychological Perspective remains to this day heavily debated with physiologist supporting its study and other calling for its abandonment. The Behaviorist Perspective The Behaviorist Perspective was developed by accident, early in the twentieth century by Ivan Pavlov. McLeod  (2007) “Behaviorism is primarily concerned with observable behavior, as opposed to internal events like thinking and emotion.” This perspective is that people have no free will and environment determines their behavior. New behaviors and reactions are learned through our interaction with our environment. We learn new behavior through traditional or operant conditioning over time (McLeod, 2007). Behaviorism was the dominant perspective in psychology...

Regulatory Behavior

...we behave the way we do, why we express emotion, have feelings, or experience hunger? How does it all work? The human body is comprised of systems all working together to complete an action or a coordinated set of chemical reactions initiated by the nervous system. The nervous system is part of a human’s body that controls voluntary and involuntary behaviors by transmitting information throughout different parts of the brain and the body via neurons and axons. The nervous system consists of two main parts, the central nervous system (CNS) which contains the brain and spinal cord and the peripheral nervous system (PNS) connects the brain and the spinal cord to the rest of the body. Within the peripheral nervous system you have the somatic nervous system. The somatic nervous system consists mostly of axons that transport messages from sense organs to the central nervous system and from the central nervous system to the muscles (Kalat, 2013). Also within the PNS is the autonomic nervous system, which controls the heart and other organs. The autonomic nervous system consists of two parts, the sympathetic and parasympathetic nervous systems. The sympathetic nervous system prepares organs for fight-or-flight activity such as increase heart rate, while the parasympathetic nervous system does the opposite decreasing heart rate. Both systems work together to regulate involuntary bodily functions and behaviors. One example of regulatory behavior is human reproduction and......

Forms of Psychology

...what have made the foundations and history of psychology. The field of psychology started in the late nineteenth when researchers became to experiment and explore what they believed caused the mind to function. The two earliest ideas and thoughts were structuralism and functionalism. Structuralism came about by Edward Titchener, he basically studied the basic thoughts and ideas of consciousness or the mind (Kowalski & Westen, 2009). He thought that if he studied everything that came through the mind, it would give a good insight as to how the mind functioned. Functionalism on the hand studied the functions or processes that came about in helping people adapt to environments. William James, one of the founders, believed that the actual study and observation of people and animals could help discover why they behaved the way they did. It emphasized that people were different (Calkins, 1906). From these two theories and ideas came many other perspectives or schools of thoughts. These are the ones that are better known in today’s society. The first is the psychodynamic perspective, which was brought about by Sigmund Freud. This perspective is based on three main ideas. Those are that people’s actions are...

...Biopsychology The brain is the control centre for the body and it sits in the skull at the top of the spinal chord. The brain is so complex that doctors and scientists still don’t know what some parts do. The brain is made up of different sections consisting of the frontal, parietal, occipital and temporal lobes. Memory Part of the brain that is responsible for memory is also known as the hippocampus, it is located within the temporal lobes, adjacent to the amygdale. The hippocampus is involved in memory forming, organizing and storing information. It is particularly important in storing new memories and connecting emotions and senses, such as smell and sound to, memories. A case study of H.M. (1953) highlights how important the function of the hippocampus is. H.M. was a man who suffered from epilepsy who had surgery to remove the hippocampus to prevent his severe symptoms. After his operation he suffered from major memory loss, which then went on to cause an inability to transfer new information into his long term memory. This resulted in the realisation that the removal of the hippocampus can have detrimental effects on the brains memory. Language and speech The Boca’s area is one of the main areas of the brain which is responsible for producing language. It is located in the lower portion of the left frontal lobe and was discovered by French neurosurgeon Paul Broca .He realised that people who had language difficulties often had damage to this area of the brain.......

Human Brain

...process by which viruses cause disease. Viral disease is a sum of the effects on the host of virus replication and of the immune response. Interest in viral pathogenesis stems from the desire to treat or eliminate viral diseases that affect humans. This goal is achieved in part by identifying the viral and host genes that influence the production of disease. Progress in understanding the molecular basis of viral pathogenesis comes largely from studies of animal models. The mouse has become a particularly fruitful host for studying viral pathogenesis because the genome of this animal can be manipulated readily. In some cases, non-human hosts can be infected with the same viruses that infect humans, but close relatives of human viruses must often be used. Viral Entry Three requirements must be satisfied to ensure successful infection in an individual host: • Sufficient virus must be available to initiate infection • Cells at the site of infection must be accessible, susceptible, and permissive for the virus • Local host anti-viral defense systems must be absent or initially ineffective. To infect its host, a virus must first enter cells at a body surface. Common sites of entry include the mucosal linings of the respiratory, alimentary, and urogenital tracts, the outer surface of the eye (conjunctival membranes or cornea), and the skin (Fig. 1).

Opium Research Paper

...Opium, a highly addictive narcotic consumes a reddish-brown color to the eye and is very heavily scented; prepared from the opium poppy. It has been used as an analgesic and an antispasmodic. While opium is made up of a “cocktail” of drugs, the most active is morphine. In recent years, other derivatives for example heroin have been widely used.(IC) Studies have shown that as many or up to 50 alkaloids can be derived from opium and further processed. It distinctively originates from two groups, phenanthrones and morphine, in which I morphine is the most prevalent alkaloid, formulating up 10-16% of the entire drug(IC). Opioids are primarily used to treat pain, but if often abused for a euphoric feeling it causes. Opium can be consumed several different ways, the most common and traditional way is by ingestion. Smoking opium allows for the effects to be more controlled, as it is not really smoked, but vaporized. Another common method of administration requires making opium in the form of a tea and drinking it. This method is more dangerous than inhalation...

Malnutrition and Academic Performance

...quantity or quality of nutrients to maintain the body system at some definable level of functioning. It has been estimated that 37-80 percent of all pre-school children in the developing countries like Philippines suffer from protein calorie malnutrition as assessed by the manifestation of syndromes, nutritional indexes, and weight deviations (Bengoa, 1974). Mild to moderate malnutrition, also called chronic under nutrition, is much more common than severe forms, and is often difficult to recognize. The severe forms are either due to insufficient protein and calories (marasmus) or to an acute protein loss or deprivation (kwashiorkor). At present, when increasing investment in our educational programs is being made to improve the performance of the schoolchildren however, to some extent this are being wasted. Children are not reaching their full intellectual potential consequently, predispose to school failure. In public elementary schools particularly the Kalibo Elementary School I, where malnutrition is prevalent among schoolchildren, it is observed that children has low attention-span, lack interest and decreased ability to focus on tasks, and restlessness. These likely to interfere with their learning ability and in this way resulted to their poor school performance. However, this has yet be proven, whether malnutrition impair the learning ability and school performance of schoolchildren. It is for this reason, necessary to study the effects of malnutrition on the learning......

In order to understand a person, his or her biology, psychological experiences, and cultural context must be deciphered (Kowalski & Westen, 2011). This paper will include a discussion of the major schools of thought in psychology and the major underlying assumptions of these schools of thoughts, or perspectives. In addition, the primary biological foundations of psychology that are linked to behavior are identified. Major schools of thought in psychology According to Kowalski and Westen (2011), psychology has several schools of thought “that can be used to understand psychological events” (p. 13). The earliest schools of thought were structuralism and functionalism. Structuralism used introspection to reveal the structure of consciousness and functionalism searched for reasons for the psychological processes that helped people adapt to their environment. Other perspectives in psychology are psychodynamic, behaviorist, cognitive, and evolutionary. These perspectives were developed independently of one another; however, they have all made considerable contributions to the psychology arena. There are phenomena at the center of each of these perspectives that the other perspectives do not...

...part of the brain that play. Vital role is the parietal lobe and the central nervous system, sensory neurons sending messages to the central nervous system which gives sensations to the missing limb. There are three characteristics in phantom limb  and there are currently three different types of treatments to reduce pain. Phantom limb is reaction to the rewiring of the brain due to an adulation of limb and reaction of the central nervous system. There are currently three types of treatment; immerse virtual reality, prosthetic usage and mirror box to help reduce or remove phantom limb. Introduction Phantom limb is a temporary or long term effect on the brain and body that occurs only post amputation of a limb for an intermittent period of time. Phantom brain can be categorized as a mental disorder, and is assumed to originate from the stem of the region of amputation. There are three types of characteristic in the phantom complex. The first is phantom limb pain (PLP) which emphasis on a painful sensation in the spatial area of the missing limb. Phantom limb sensation(PLS) which is anytype of sensation in relation to the absent limb without any pain. Lastly is the description known as stump pain where the amputees pain is focused on the stump, (Anaseth,2001). The central nervous system plays an important role in generating and maintaining sensations and pain.

Substance Abuse and Disability

...several different categories of substances and they all have different effects on the body. Stimulants such as cocaine, amphetamines, and methamphetamines effect the central nervous system and often have behavioral effects such as mood elevations and euphoria. Hallucinogens such as MDMA, LSD, and psilocybin can have hallucinogenic effects on a person’s perception, mood, and state of mind. Marijuana is described as a drug that effects the central nervous system and can cause a euphoric high, heightened sensory perceptions, and hallucinations in higher doses. Depressants consist of psychoactive drugs such as barbituaties, sleeping pills, and alcohol. These substances depress the central nervous system and can result in decreased motor activity and a sedating effect (Marini & Stebnick, 2012, pgs. 295-99). Opiates include substances such as heroin, morphine, hydrocodone, oxycodone, and codeine. These drugs have an effect on the brain with feelings of a euphoric high and can be psychologically and physiologically addicting. Inhalants are another class of abused substances which can be solvents, glue, paint, gasoline, and other chemicals that are sniffed, huffed, or inhaled into the lungs. Benzodiazepines and sedative hypnotics have a tranquilizing effect or anxiety reducing effect on the central nervous system (Marini &...
