Controversy on the Front Lines Women should be allowed to fight on the front lines. Women should fight on the front lines because, they have taken part in war efforts already, they fought for their own right to vote, and if they fit the position there should be no reason for them not to. From the beginning women have had some role in war. Whether it be staying at home, being a single parent, or enlisting and helping where they are told. Native Americans were able to treat men and women as…

There is much controversy that has arisen concerning the topic of causative factors associated with Alzheimer’s disease; however, according to the Mayo Clinic in their article “Alzheimer’s Disease” (2015), “scientists believe that for most people, Alzheimer's disease results from a combination of genetic, lifestyle and environmental factors that affect the brain over time.” Even though there are many controversial opinions about causative agents, one common factor that is present in many…

Humans are animals. We are one species in a complex kingdom that includes many other species with central nervous systems designed in much the same way as our own, like their immunological systems, skeletal systems, etc. That is why humans are in the animal kingdom. We share significant similarities in many ways. Why would it surprise us that other species have highly evolved cognitive (mental), learning, timing…

The human brain can be modelled as a matrix of dots. Each dot's color can be flipped to opposite colors. When a baby is born, it's brain matrix consists of a very low m x n dots. As the baby grew, the number of m and n changes (usually both increases in magnitude). The magnitude of m and n are not necessarily the same, as both number defines the capacity of an individual's brain. The larger the product of m and n, the bigger the capacity to think. Capacity of the human brain can be narrowed…

When looking at various control interfaces for power wheelchairs, the traditional joystick is one that is often first thought of. For people who have limited use of their upper extremities, a traditional joystick will not work. A multi joystick is a type of interface that is multifunctional and requires reduced force. The technology was designed for people with limited muscle power or for people who have neuromuscular diseases (“Alternative Drive Controls”, n.d.). For example, it can be used for…

Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits analgesic activity in animal models. The mechanism of action of Ketorolac, like that of other NSAIDs, is not completely understood but may be related to prostaglandin synthetase inhibition. The biological activity of Ketorolac tromethamine is associated with the S-form. Ketorolac tromethamine possesses no sedative or anxiolytic properties. The peak analgesic effect of Ketorolac tromethamine occurs within 2 to 3…

Pathophysiology of Huntington’s Disease Huntington’s disease is a genetic neurodegenerative disorder that causes both motor and cognitive dysfunction in those diagnosed. Since Huntington’s is an autosomal-dominant disorder, those expressing the gene will develop the disorder, and children of the affected individuals will have a fifty percent chance of inheritance (Walker, 2007). The effect of this disease causes deterioration in many areas of the brain, however, this deterioration occurs at a…

Introduction Frontotemporal dementia (FTD) is a rare, progressive brain disorder that causes memory loss. FTD describes a range of diseases that often start with changes in behavior, speech, and decision-making processes. As FTD progresses, it affects short-term memory. Over time, FTD causes the frontal and temporal anterior lobes of the brain to shrink. These are the parts of the brain that control behavior and speech. There are three main types of FTD: Behavioral variant FTD. This is the most…

The eye is one of the significant special sensory organs that is responsible for vision. Through observation, we handled a cow’s eye and discerned our findings to our knowledge of a human’s eye. A cow’s eye has similarities, such as the overall layers of the eye like the sclera, choroid, and retina layer, to that of a human’s eye. Also the structures and organs contained within these layers. Also, we discovered many other anatomical structures that are much the same to a human's eye during the…

EFFECTS OF POVERTY ON COGNITIVE DEVELOPMENT Abstract This paper explores the effects that poverty has on cognitive and brain development in childhood. Living in poverty places children at very high risk for problems across a variety of domains, including schooling, behavioral regulations, and health. Hanson, J.L., Hair, N., Sheen, D.G., Shi, F., Gilmore, J.H., Wolfe, B.L., Pollak, S.D. (2013). Environmental stressor of poverty results in many adverse effects on children, none of which are good.…
