Many believe that using Marijuana for medical purposes can lead a person to an addiction, while others think that Marijuana is a wonderful medicine to help diseased patients. People are against of marijuana legalization because they don't know enough information about their benefits.…

healthy cells making it harder to or unable to function. An eye cancer, for example, may result in the loss of vision in the affected eye. Retinoblastoma is a rare cancer that forms on the retina of the eye after a genetic mutation occurs in retina nerves (National Cancer Istitute). These mutations can be spotanious or passed down through the genes given to us by our parents (KidsHealth). Twenty percent of cell mutations causing retinoblastoma are hereditary (Geneticts Home Refrence). Only one…

ABSTRACT Diabetic retinopathy (DR) remains a major complication of diabetes and the leading cause of blindness among adults worldwide. DR is a progressive disease affecting both type I and type II diabetic patients at any stage of the disease, and targets the macrovascular and microvascular systems of the retina. DR results from multiple biochemical, molecular and pathophysiological changes to the retinal vasculature which affect both microcirculatory functions and ultimately photoreceptor…

survival. In mammals, the principal regulator of the circadian clock is a group of nerve cells known as the suprachiasmatic nucleus (SCN), which is located in the hypothalamus, an area found at the base of the brain that is responsible for controlling the endocrine system. The SCN is connected to the nerve cells in the eyes that send signals to SCN cells when they sense the presence or absence of light. When optic nerve cells sense light in the daytime, SCN cells send efferents in the form of…

The Sensory System is a very complex System in the body. There are several paths in the Sensory System from places like the eye,ear,skin,nose,etc. to the brain. I am going to tell you about the pathways from the ear to the brain, the eye to the brain, and the nose to the brain. Also, I am going to write about three Geico advertisements I watched and explain the message from the advertisement and what personal factors might be affecting my perception of the advertisements. The sound wave path…

marijuana will be the next topic this country will have to face and we have to be ready and informed when that day comes. Not only has marijuana been used for medication but its also can help out on diseases. A disease called glaucoma damages the optic nerve which in over time can lead to blindness. A recent studies show that marijuana can slow down this process and or can completely cure this by…

For the Disease and Disorder Project, I choose Multiple Sclerosis as my topic. Multiple Sclerosis, or MS, affects about 400,000 people in the United States and over 2.5 million people around the world. (Adelman G, et al. 2013) It can affect any race or gender. I chose this autoimmune disorder because I already had some prior knowledge of what it is and how it affects the host. Its effects can be permanent and it is an incurable disorder. This research really opened my eyes to how Multiple…

men to complete task creatively. Suggesting that women can emphasize more with others than men because of this structural constraint. The fronto-orbital area is the part of the cephalic region that hold the eyes and is the insertion point of the optic nerve, these are also proven to be structurally larger in women than men. Explaining why women can see up to 30 more shades of colors than men. However there is proof that men have a larger fronto…

Once alcohol enters the body, affects the CNS known as the central nervous system (Nemours, 2015). According to the article entitled “The Anatomical and Cellular basis of Immune Surveillance in the central nervous system” the “brain, spinal cord, optic nerves and retina, and post-mitotic, delicate cells” (Ransohoff and Engelhardt, 2012) make up the human central nervous system. The central nervous system controls a person ability to converse, communicate, and walk, thus, basically, every sort of…

Glaucoma is an ocular disease which destroys the optic nerves in the eye due to an increase in the intraocular pressure. This disease is the second most common cause of blindness in the world and Canada (Noertjojo et al. 2006), and the most prevalent form of the disease is Primary Open Angle Glaucoma (POAG). It is estimated that by 2020, there will be almost 80 million people in the world with both primary open angle glaucoma (POAG) and angle closure glaucoma (ACG) with POAG more prevalent.…
