Peripheral nervous system

My eighty-four-year-old neighbor, Colette, has come to me to talk about how she is having eye complications after a recent fall to the head. After reviewing the symptoms, I think Colette has damaged her oculomotor nerve, cranial nerve IV. Furthermore, the inferior rectus is in charge of depressing, adducting, and laterally rotating the eye (Schuenke, Schulte, & Schumacher 2016). Similarly, the inferior rectus muscle positions the eye infraversion, dextrodepression, levodepression,…

The Critical Noncarcinogenic effect of acrylamide is classified as “Degenerative Nerve Changes”. This means that chronic ingestion of acrylamide resulted in an observable damaging of the central and peripheral nervous system, thus classifying it as a neurotoxin. This conclusion was determined after the results of two separate chronic (2year) drinking water studies performed on lab rats. (Friedman et al., 1995, 224307; Johnson et 14 al., 1986, 061340). The doseresponse data for acrylamide was…

The nervous system in the body is divided into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and…

The cranial nerves are made up of twelve categories with different functions. These categories are numbered with Roman numerals. The first cranial nerve is the Olfactory nerve which is involved in the sense of smell. The function of sense of smell works when the receptors in the epithelium of inside the nose sends signals to the brain (World of anatomy and physiology, 2007). The second cranial nerve is the optic nerve which is involved with the ability to see. The third cranial nerve is the…

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…

protein in the brain creating Lewy bodies [5]. When -synuclein misfolds it is insoluble and will aggregate, leading to inclusions within the cell bodies and its intracellular processes [6]. Furthermore, Lewy pathology (LP) can be found in the peripheral nervous system and spinal cord in PD [7]. Alpha-synuclein becomes present…

Pathogenic Mechanism of Alzheimer’s disease The pathophysiology of Alzheimer’s disease is complex, involving several neurotransmitter systems and pathophysiologic process. The three hall marks of Alzheimer’s disease are the presence of neuritic (senile) plaques, neurofibrillary tangles, and amyloid angiopathy (Grossman & Porth, 2014). The neuritic plaques are patches or flat areas composed of clusters of degenerating nerve terminals arranged around a central amyloid core. The amyloid core has…

contains different parts like the central nervous system, peripheral nervous system, somatic nervous system, autonomic nervous system, sympathetic nervous system, and parasympathetic nervous system. The central nervous system is the largest part of the nervous system, it includes the spinal cord and the brain. Peripheral nervous system is the nervous system that serves the limbs and organs. Somatic nervous system is the part of the peripheral system that picks up stimuli from the outside…

that affects their ability to think, but it also causes people to learn at rapid speed. “The human brain is one of the most complex organs in the human body. It is protected by our skull and tissue” (Webmd). The brain is the center of our nervous system and it sends signals all throughout our body. As advanced as science is today, doctors and scientist still have many questions about the human brain, only having limited answers. “The brain made up of specialized functions that work…

Glial Cells are supporting cells in the nervous system (central nervous system [CNS] and peripheral nervous system [PNS]) which aid in the efficiency of neural operations in the nervous system, (Carlson, 2013). Carlson (2013, p.36) indicates the general functions of the glial cells as: keeping neurons in place; supplying neurons with nutrients and the chemicals needed to communicate with each other; protecting neurons from each other to promote coherent messages; and “destroying and removing the…
