  • Parkinson Disease

    The Parkinson is a disease that make Causes damage to the brain For lack of a neurotransmitter that is called dopamine and they are asked to be dopamine, dopamine is a neurotransmitter for the brain to send impulses to the motor nerves of the human body so that the body's bodies can work better and is important in all nerve responses that are related to the expression of emotions; Can be administered dopamine in the treatment of various types of shock like the Such as Parkinson's tremor Which…

  • Dopamine Essay

    that sends messages from the brain and different nerve cells in the body. Dopamine is considered a chemical that is produced in three different areas of the brain. The areas of the brain that are affected by Dopamine are the hypothalamus, substantia nigra pars compacta and ventral tegmental area. Dopamine is linked to movement, memory, attention, inhibition of prolactin production, learning, sleep, mood, pleasurable reward, behavior, pain processing and cognition in the body. Symptoms of…

  • The Human Body: The Peripheral Nervous System

    The human body is a unique formation that represents how every component, whether it’s a chemical, cell, or organ all have an important role to have a healthy physiological and anatomical system. Dividing into which part of the body they control most, they create the organ systems that are the nervous, respiratory, articulatory, digestive, endocrine, and the cardiovascular system. The neurological, or the nervous, system is our control system that regulates impulses, chemicals, and commands to…

  • Cocaine Addiction

    Cocaine is a psychoactive drug affects the limbic system of the body, which controls pleasure and motivation. In 1859 Albert Niemann, German Chemist, isolated cocaine from the leaves of the Coca plant which is located in the Andes Mountains of South America. It is the second oldest psychoactive drug and in the Medical field it is classified as a Schedule II Drug; meaning it can be used in a controlled medical setting but it is highly addictive. When cocaine is used as a recreational drug it…

  • Parkinson´s Disease: A Case Study Of Parkinson's Diseases

    Imagine a seed of an apple tree planted inside of ones’ brain- it starts off tiny until its growth encompasses the nerves of the entire body. The branches start to intertwine with the muscles and halt simple movements that one could once do. Their growth creates stiffness in the limbs while the trunk and the leaves soak up all of the dopamine in the brain. The apples are the lewy bodies (clumps in the brain). One never knew how this seed got planted or how it was attracted to their brain but it…

  • Cerebellum And Basal Ganglia Case Study

    In the past it was believed that the cerebellum received information from various areas of the cortex and projected information to the primary motor cortex via thalamus, thus fine-tuning a movement (19). It was also believed that the Basal ganglia was involved with the inhibition and selection of action commands (19). These views suggest the involvement of both cerebellum and Basal ganglia(BG) in purely motor function. But that is not the case, recent studies have found a connection between the…

  • What Is Dysarthria?

    DYSARTHRIA WHAT IS DYSARTHRIA? Speech production is a complex process involving the co-ordinated contraction of a large number of muscles controlled by the nerve impulses originating in the motor areas of cerebral cortex. The organs that are involved in speech production are the lips, the tongue, the vocal folds and the diaphragm. When these organs don’t function efficiently, the speech tends to be unclear. One such condition which results owing to the malfunctioning of the speech organs is…

  • Functional Magnetic Tolerance Imaging Device Analysis

    Like any other cells in the body, when neurons are activated they consume glucose and oxygen to fuel their activity and they produce metabolic waste. According to Sadock, Sadock, and Ruiz (2015), a functional magnetic resonance imaging (fMRI) device works from this principal by using high magnetic fields and radio frequencies to indicate activity. The fMRI helps the medical professional to peer into brain activity, not by measuring brain activity directly, but by observing the flux of oxygen…

  • Synaptic Dysfunction

    Synaptic dysfunction: Studies in a number of the PARK2 knockout lines suggest the presynaptic dopamine transmission is perturbed. In the Park2tm1Shn knockout line, the evoked dopamine signal of neurons was reduced and could not be restored with DAT inhibition (Goldberg et al., 2003). The normal function of Parkin in dopaminergic synaptic transmission is been explored and found that the signal is lower in parkin-/- mice relative to the control, indicating that loss of Parkin indeed decreased DA…

  • Parkinson's Disease Case Study

    paraquat herbicide and traumatic brain injury in the development of Parkinson’s disease. There seems to be a common connection between pesticides and other common farming poisons and the development of Parkinson’s disease due to the death of the substantia nigra pars compacta dopamine neurons. There also seems to be a correlation between PD (Parkinson’s disease) and traumatic brain injury that left the victim unconscious for over five minutes. The reason for this controlled case study was to…
