Central nervous system disease that cause vertigo include disease of the brainstem. vascular nervous system causes malformations, tumor of the brainstem and cerebellum ,multiple sclerosis, , vertebrobasilar migraine. Vertigo of central origin often becomes disabling. The associated nystagmus is often non fatigable, the orientation of this type of vertigo is vertical rather than horizontal, without latency, and unsuppressed by visual fixation. ENG is useful in documenting these characteristics.…

Multiple Sclerosis is a disease where the immune system eats away at the protective, myelin or layer covering nerves. This disease is also known as MS, which is Multiple Sclerosis abbreviated. MS has a very big effect on a person and their family, knowing this because my aunt was diagnosed with MS before she passed away. Currently there is not a known cause from Multiple Sclerosis, but science have theories. Some believe that it is a result of combination of genetics, and some believe it is…

birth. When being diagnosed with Cerebral Palsy mostly only the child’s brain is affected. This disorder results in several issues with the developing nervous system. These exact issues in the nervous system have yet to be found in clinical findings. The part of the nervous system that is affected is the Central nervous system. The central nervous system is damaged before, during, or shortly after birth. If the brain is damaged before birth this is called prenatal. Prenatal disturbances of…

their mouth. Human have 5 different types of receptor cells that responds to five primary taste: salty, sweet, sour, bitter, and umami. Human are able to interacts with the world through the peripheral nervous systems which uses nerves to connect the body’s sensory organ to the central nervous system. The receptors of taste are found on specialized taste receptor cells. These cells are on the 2,000 to 10,000 taste buds that a normal human has. Two third of the taste buds are located on the…

properly. …. Function: The astrocyte cell is a type of glial cell, very common in the Central nervous system, and present for the purpose of providing structure and insulation for neurons. The astrocyte itself has the function of keeping nerve cells in place and protecting them, as…

Have you ever wondered what is happening in your brain? Or how your nervous system really works? Well then you would want to learn about neuroscience. Neuroscience is the study of the structure or function of the nervous system and brain. Neuroscience also focuses on the behavioral and cognitive functions of the brain. One of the current scientists, whom is considered an expert, in the field of neuroscience is Dr. Ben Carson. Dr. Ben Carson was born in Detroit, Michigan, and was raised by a…

It was a blustery and gloomy morning as I trudged along the weathered pavement to the entrance of the church. My Sympathetic Nervous System was revved up as I anticipated what lie behind the faded and chipped paint door. Upon entering the room I was jovially greeted by a man with a melodious “Welcome!” There were about thirty people from all different lifestyles, huddled in the room around three long wooden tables. Men and women, some appeared jovial and others exhibited a flat effect. The…

Neurons are the cells specialized to receive, conduct, and transmit signal to the nervous system. The development of neurons starts early during the embryogenesis. After the fusion of sperm and egg, zygote is formed which is further divided to form blastula eventually leading to gastrula stage of development. Gastrulation begins as invagination of cells in the embryo leading to the formation of three germ layers. Formation of notochord from the mesodermal layer marks the beginning of neurulation…

Human and animals are biologically similar having the same set of organs, blood stream, and central nervous system, which is why they’re affected with the same diseases and health conditions. DNA of chimpanzees are 99% similar to humans. The HPV vaccine shot we all get, the vaccine came from experimentation on chimpanzees. Animal experimentation is has it’s…

This disorder is when someone cannot and never has had the ability to perceive or feel any sort of pain done to their body. People with Congenital Insensitivity to Pain although unable to feel pain, can feel the difference between hot, cold, and dull and sharp, but cannot feel if something is burning them. People with this disorder also have very overt autonomic symptoms, so they tend to show a lot of their actions that are supposed to be involuntary. Congenital Insensitivity is a genetically…
