Substantia nigra

Parkinson’s disease, is the disorder of the brain which causes shaking and unsmooth movements. Parkinson’s disease is a very horrible fate for multiple people. Muhammed Ali was a boxing legend and Parkinson’s disease ended his career, and probably ruined his life. Right now more than one million american’s have Parkinson’s Disease, and these are the only American’s know how horrendous and difficult it is to have Parkinson’s. Parkinson’s shaking is caused by tremors, a tremor is a non rhythmic shaking

INTRODUCTION This case study focuses on Richard who is 80-year-old and lives with his daughter Cathy and son in-law Bronco in a city metropolitan suburb. His other daughter, her twins, and his son who is ill live within two streets. It takes for Cathy and Bronco two hours to get to work, so they are not home from 6 a.m. to 6 p.m. Richard usually gets up after Cathy and Bronco have gone to work and spends most of his time watching the television. Meals on Wheels are delivered everyday for lunch.

what happens neurologically. Nolden, Tartavoulle, and Porche (2014) explain that the brain structures affected by the disease are known as the substantia nigra and the basal ganglia. The role of the basal ganglia is to provide control of fine motor movements. What happens with PD, is there is a loss of dopamine-producing neurons from the substantia nigra which causes a deficiency in dopamine levels. Without a sufficient amount of dopamine, there are not enough chemical messages being transmitted

muscles. The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. First, I will explain what part of the brain is responsible for dopamine. Dopamine is located in the substantia

lobes send a signal through the glutamate neurotransmitters which end up in the striatum. The excitatory signal ends up in those neurons which converts the signal from excitatory to inhibitory and leads to the globus pallidus internus and the substantia nigra pars reticulata. The GPi and the SNr to do not inhibit the thalamus; the thalamus is where the function rests. Instead, it sends messages to the cortex allowing for the movement that is desired to occur. The motor cortex finally sends that processed

Neurotransmitters are chemicals from the brain that send messages to the rest of the body to initiate an action or response. Dopamine is a neurotransmitter secreted from three areas in the body: 1) dopanergic neurons in the VTA of the midbrain, 2) substantia nigra pars compacta, and 3) arcuate nucleus of the hypothalamus. It is different from most neurotransmitters in that it is both inhibitory and excitatory. It also has five different receptors that it can bind to, making up only a small part of what

The biological basis of behavior has become apparent throughout this semester. The mind and brain are connected in ways that are still amazing scientists today. However, there are three important topics discussed in this psychology class that have influenced me into thinking that the mind is located in the brain. The science behind Parkinson’s disease, the inaccuracy of memory, and biology of circadian rhythms have convinced me that the brain and the nervous system do impact the mind and behavior

Parkinson’s disease (PD) is the second most common neurodegenerative disease in the country. It is characterized by tremor, rigidity, bradykinesia, and impaired muscular coordination (Wei et al., 2014). It affects approximately 50/100,000 people over the age of fifty. PD can occur sporadically, but affects one third of people with two or more first-degree relatives with the disease (Duffy, 2005, p. 190). Several systems are affected in the population of Parkinson’s disease. These systems include

disorder; it rises from an unknown cause and increases in severity over time (Ronken). The disease was named after English physician James Parkinson, who first described it in 1817 (Weiner). PD can be defined as the degeneration of neurons in the substantia nigra, which is the area of the brain that contains dopamine cells and regulates movement. As the degeneration of neurons occurs, the brain loses the ability to generate body movement, which leads to the characteristic symptoms of PD (Weiner). The

Parkinson’s disease is a disease that is associated with disorders of the basal ganglia. Parkinson’s disease is a disease where the muscles cannot be still and the person shakes a lot. The shaking is caused by disorders inside the brain and the basal ganglia. When the person with Parkinson’s disease is not using their muscles, or moving, this is when the uncontrolled movement or tremors start happening. Parkinson’s disease also causes a person to be slow in movements. They may understand and know
