Brainstem

exist in the subarachnoid area or in the basal cisterns (Iliescu, 2015). “The accumulation of blood can increase the intracranial pressure and compress the brain” (Craft et al., 2015, p.199). This can cause the brain forced downwards towards the brainstem and spinal cord then further form a brain herniation (Craft et al., 2015).…

Introduction Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, affecting nerve cells in the brain and the spinal cord. To better understand the breadth of this disease, it is vital to define the following terms. The word amyotrophic means “without muscle nourishment”, which refers to the loss of signals the neurons normally send to the muscles. Lateral means “to the side”, which refers to the location of the damage in the spinal cord. Sclerosis means “abnormal…

That act of dreaming itself occurs during REM sleep. According to the journal article Mental Processes and the Brain During Dreams, author Miranda Occhionero, explains “During REM sleep the level of activation results in the frequency at which brainstem reticular neurons fire . . . Moreover, the ascending activation system was hypothesized to activate other structures for dream imagery . . .” (Occhionero 55). From this passage it is…

significant signal loss in regions immediately adjacent to the oral cavity (e.g. facial structures and orbits) as well as image distortion over variable portions of the brain. These image distortions are most pronounced at the base of the brain, the brainstem, and the blood vessels that perfuse the brain. The artifacts are most severe for diffusion weighted imaging (DWI), gradient echo (GRE) imaging, MR angiography (MRA), susceptibility weighted imaging (SWI), and MR spectroscopy (MRS). Although…

The advancement in medicine has changed the world. Many people have been cured of or have found a solution to their pain for diseases that were once fatal or painful, but even with these advancements some diseases cannot be cured. In some extreme cases many have wanted to end their life either from lethal injection or denied care, but is it legal? Does a person have the right to die if he or she chooses? Who can deny or who would deny someone death if they are in pain? Is it wrong to kill them,…

chronologically. The second mode involves a far more difficult task than the first, to develop a philosophical partnership with the author. This partnership requires an investment in the material, a submersion that allows the linkage between the reader’s brainstem and the author’s arguments or ideas so that one’s breathing and temperature coincide…

Cardiovascular diseases are conditions that pertain to the heart and blood vessels that interfere with the normal functions of the body. Arteries are blood vessels that carry blood away from the heart. The heart then acts as a pump and provides blood to all parts throughout the body. Occlusion due to plaque buildup interferes with blood flow. The arteries begin to narrow and blood flow is restricted to the brain. Brain cells are deprived of oxygen and begin to die resulting in a cerebrovascular…

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

The near death experience was first defined to be a spur of consciousness leading to an altered-reality experience on random individuals who reach the state of clinical death by a lack of oxygen to the brain that implies complete unconsciousness on those individuals (Khanna & Greyson, 2014, p. 1605). Near death experience recounts highlight similarities among those who experience them. Characteristics such as out of body experiences, diving into darkness to then transport into a light-filled…

I need my brain to know when to move. When playing volleyball, I need to be able to move around in order to get to where the ball had been hit. In order to do this my brain uses neurons to transmit signals to my body that allows me to make quick motions. Sensory neurons send messages from my muscles and sensory organs, like my eyes and ears, to my brain and spinal cord. My brain then processes that message and sends a response back to my muscles via motor neurons. If, for instance, one of my…
