The system is what makes up our body, it's the foremost sophisticated of the various systems within the body, and it's conjointly a network of nerve cells and fibres that transmits nerve impulses between components of the body. This essay will explore the structure and functions of the system similarly as well as looking in depth at the neurons and how they communicate The system is split into two components, the central nervous system- which incorporates the brain and also the spinal cord. The…

Write an essay describing the neuron function. The nervous system is made of the central nervous system which includes: - The brain - Spinal cord It is also made up of the peripheral nervous system which is consisted of the sensory and motor neurons and lastly the autonomic nervous system which helps in modifying the body processes such as the digestion and heart rate for the body to function properly. [1] Neurons are excitable cells that help in processing and transmitting information. Even…

The brain is one if not the most important organ in our body. It controls the vital functions of the body including speech, thoughts, memory, vision, breathing, movement and more. Since the brain is such an important organ, any little change or imbalance in the brain can lead to a serious problems. Any amount of swelling, bacteria, or abnormal growth in the brain could lead to a life threatening illness. An abnormal growth, such as a tumor impedes on different functions depending on where that…

injected through the vein to help cure strokes. Also, this organ has a helmet like structure called the skull or the cranium, this is the outer layer that protects the organ from any damage or injury. The structure of the brain is made up of cerebellum, cortex, cranium, basal ganglia, brain stem, spinal cord.[www.m.webmd.com] The…

but also, hearing improved. For the mice placed in darkness, the tested neurons fired faster in response to auditory stimuli and could discriminate sounds better. These mice also developed more synapses between the thalamus and the auditory cortex. The cortex is an advanced sensory processing centre. The fact that neural connections developed in this area suggests that it might…

Primarily, Cerebral Palsy was called “Little disease” because the first medical description of this disorder was written by an English surgeon, William John Little (1810-1894) in late 1830s. Little described it as a brain injury, caused by asphyxia (Oxygen deficiency). He approached that this incidence happened during complicated processes of delivery that suffocated the child, and the child couldn’t get enough oxygen. The lack of oxygen damage the nervous system of the brain and cause spastic…

This is a concise description of the changes that may occur in a person who has suffered damage in a region of their brain. The arear of the brain to be discussed is the Corpus Callosum, with references to Sperry’s split Brain research. The brain is the control centre for the body at the top of the spinal cord. The brain has three main parts, the cerebellum, and the cerebrum which has two parts, the left and right hemispheres and the brain stem. The corpus callosum is a thick band of nerve…

There are many studies which suggest that cortical connection mostly occurs through feedback connections. However, feedback connections are not clearly understood. In these research papers, the experimenters focus on the role of feedback in the visual cortex. Although research has been done on this topic, it is difficult to study cortical feedback signals. I will use research by researchers Nassi, Lomber & Born (2013) for the first article. For the second article I will use the work of Bastos,…

The frontal lobe is often the area of the brain that is damaged in motor vehicle accidents as well as sports accidents as it is placed in the front of the skull, an area that could be damaged due to its location. For example, in a motor vehicle accident if the head were to hit the windshield it would be the frontal lobe that hit first. The frontal lobe is responsible for multiple functions of the body such as emotions, motor capabilities and cognitive impairments meaning that if it is injured…

An anatomical change that Addison's disease can have on the nervous system is hyperpigmentation. With the insufficient levels of glucocorticoids, found in the blood, causes the pituitary gland to release more adrenocorticotropic hormone, or ACTH. In some cases, parts of this hormone are converted into melanocytes, which initiates production of melanin. This leads to darkening of skin cells in areas, such as 'Palmar creases, flexural areas, sites of friction, recent scars, vermilion border of the…
