“The Black Walnut Tree” “The Black Walnut Tree” by Mary Oliver begins with the line “My mother and I debate”. There are two characters introduced: the narrator and her mother. In a typical family, there is a mother, daughter, and father. The lack of a father in this introduction stands out. This is furthered by the line “two women trying / in a difficult time to be wise”. The author highlights the lack of the father once again by saying “two women”, in order to clearly demonstrate the lack of male

The Past is Rooted Change is inevitable; as the years go on, everything is always either improving or weakening, but still changing. Nothing can prevent change, but there are still those who ignore it and refuse it. Individuals refused to accept their past because they do not want to change, they want to focus on the present. In Mary Oliver’s free verse poem, The Black Walnut Tree, the daughter discusses the argument with her mother regarding the selling of their Black Walnut Tree, commenting on

Provide a summary of the structures of the basal ganglia and related subcortical nuclei. Describe 2-3 disorders which occur as a result of damage to this area of the brain. The basal ganglia are a collection of deep nuclei situated outside the central nervous system, located within the white matter of the cerebral cortex (Grants.hhp.uh.edu, 2018). Gilman and Newman (2003) explain that the basal ganglia are comprised of subcortical nuclei belonging to the telencephalon, midbrain, and sub-thalamus

ganglia is composed of interconnected nuclei located in the telencephalon, diencephalon, and midbrain which include the striatum, globus pallidus (GP), entopeduncular nucleus (globus pallidus internal in humans), subthalamic nucleus, and the substantia nigra (figure1) (6,8). Although there are multiple structures that partake in the modulation of movement, the basal ganglia serves to integrate information deriving from the parietal, frontal, and temporal cortex. In particular, electrical stimulation

Care Plan of Patient with Signs and Symptoms of Parkinson’s Disease Sarah A. Bird Ivy Tech Community College Introduction J.N., a 65-year-old Caucasian female with a history of anxiety and depression, presents for diagnostic testing at Saint Mary Medical Center in Hobart, Indiana to confirm or deny a diagnosis of Parkinson’s Disease, after presenting with recent onset of upper extremity tremor affecting both sides and facial masking. Patient history also includes bradykinesia, restlessness

For example, particular neural cells in the substantia nigra pars compacta start to progressively degenerate or breakdown. The substantia nigra pars compacta is found in the midbrain. The neurons use the neurotransmitter dopamine. The neural pathway go to the caudate nucleus and putamen of the basal ganglia which is also known as the striatum. The receptors can have an excitatory or inhibitory effect depending on dopamine release by the substantia nigra. Typically, the dopamine has excitatory effects

incapacity and death over one or two decades. Clinical diagnosis of PD is currently solely dependent on the presentation of the symptoms by the patient which reflect a deficiency of striatal dopamine caused by the destruction of the cells in the substantia nigra. Imaging and other laboratory techniques can be used to

attitude towards the aging process in the medical community and American culture. The primary symptoms of Parkinson's Disease stem from the deterioration of the part of the brain that controls motor functioning (NHGRI, 1998). This region is the substantia nigra which is found deep within the brain stem and contains neuronomelanin, pigment cells, which synapse to cells of the striatum. The striatum is responsible for balance, control of movements, and

neurons indicates that in PD the defining feature is a substantial decrease in the neurotransmitter dopamine (which occurs in the nirgrostriatal brain tract; (Dauer & Przedborski, 2003). Dopamine is produced in the brain in an area known as the substantia nigra and is transported along the neurons in the brain
