Blood-brain barrier

The nervous system houses the almighty brain. The brain controls what happens throughout the body. But what happens when genetic abnormalities cause the powerful brain to be altered? One result can be the diagnosis of autism spectrum disorder. Another strong system in the body is the skeletal system, which is comprised of the strong, structural bones. When these bones are not so strong, they may begin to lack specific vitamins necessary for proper bone health. Rickets can be a result of improper…

Sensory adaptation is also known as neural adaptation. A process in which changes in the sensitivity of sensory receptors arise in relation to the stimulus called Sensory adaptation. All senses are supposed to involve in the sensory adaptation. We get used to things. This goes for lots of things in life including smells, sights, sounds, people, games, and conditions. Looks like after a while we get used to everything. Sensory systems continually adapt their responses to match the existing…

(AD), was founded by a German medical specialist DR. Alois Alzheimer in 1906, DR. Alzheimer observed Physiological changes in brain tissue of a female who recently passed away with an unusual mental illness. Her indications were unpredictable behaviour, memory loss and language problems (Duthey 2013). Alzheimer's disease is a neurological disorder where the death of brain cells causes cognitive state and psychological feature decline. A neurodegenerative kind of dementedness, is when the illness…

As a student, and a millenial living in a world that seems to demand more and more energy by the day I have come to understand the importance of replenishing ones energy. When you are constantly moving, studying, or running through a campus in pursuit of education at a moments notice you find yourself exhausted unable to think. In my personal experience, I have known the sudden sluggishness of sleep deprivation. Suddenly unable to think, or perform basic tasks such as, recalling a lecture from…

its role as an ergogenic aid (Olsen et al 2017). Caffeine is taken up by the body in a variety of steps and has a range of physiological effects. Caffeine is metabolised by the liver, and rapidly absorbed through the gastrointestinal tract. The blood concentration of caffeine peaks 15-45 minutes after ingestion, however its metabolic effects often last for over an hour (O’ Roberts 2016). It is lipophobic,…

Multiple Sclerosis is a very common disease in people around the world. For instance my beloved grandmother got diagnosed with it in 1958. She had primary progressive MS and it is known to be the worst type of MS out of the four different types. Right off, she started having symptoms such as double vision, problems driving, problems walking, tingling, and weakness in her legs along with getting infections easily. She lived at home and my grandfather hired a special nurse to stay with her all day…

A myloidosis (am-uh-loi-doh-sis) results from mutational folds of the immunoglobulin protein, forming a fibril. A fibril is a product of protein aggregation. It is still unknown what causes these fibrils to form, however scientists know that the folds are found in the light chains, also known as the Lambda chains. This specific immunoglobulinic amyloidosis is also referred to as AL or “primary” amyloidosis. AL amyloidosis is considered to be the most common type of systemic amyloidosis in…

The Brain and Spinal cord are two major components of the Central Nervous System (CNS), which controls all movement we make. Parkinson's Disease is a disorder of the Central Nervous System. People suffering from Parkinson's disease lack the ability to control motor function which cause them to lack balance and have shaky hands. By identifying the cause, symptoms and treatments of Parkinson’s, a conclusion on how Parkinson’s Disease effects the Central Nervous System can be made. The basal…

The human brain has many functions, but one of its most significant attributes is its capacity to store information, which is referred to as memory. In a paper written by Schacter, he describes the two forms of memory, “Explicit memory is reflected by conscious recall and recognition of recent information and events. Implicit memory is reflected by non-conscious effects of past experience on subsequent behavior, as expressed by such phenomena as priming, skill learning, and habit formation”…

watched the video “Do Scientist Understand the Human Brain”. In the video Bahar Gholipour, from Science Journalist interviews Dr. Gary Marcus, a neuroscientist and professor at New York University. To summarize the video content people have been studying the brain for over 200 years. Our text defines neuroscience as “the study of the nervous system, especially the brain” (Hockenbury 10). Dr. Marcus asserts that scientist don’t know how the brain works and that it is an exciting time in the…
