Diffuse Axonal Injury The tearing and shearing of axons and small vessels widespread in the white matter of the cerebral, a traumatic brain trauma of sheering forces within vessels (Park et al. 2009). The components of this injury is the acceleration or declaration of the skull followed by head injury…

Children are seen to be hyper beings that are always active and moving in some fashion; however, recent studies have shown that this may not be the case. At home, parents are responsible for providing their children with physical activities, but at school, that position belongs to the administrators. “[They] are faced with the demands of preparing children for standardized tests, [which has] reduced… physical activity programs” (Tomporowski, Davis, Miller, & Naglieri, 2007, 125-6). “The time…

individual adapts to aging depends on genetic factors as well as physical and social environments. Some of the declining health issues related to older adults include thickening of the heart muscle, stiffening of arteries, decline in lung capacity, loss of axons in the brain, decreased renal efficiency, decreased capacity of the bladder, increase in body fat, decrease in muscle mass, decrease bone mineral, and cognitive changes. (Tablaski, 2014, p.15) With healthy lifestyles, older people avoid…

Cases: 1. A 13-year-old male presents with a two-year history of progressive weaknesses in both upper and lower extremities. He finds it difficult to lift heavy objects off a shelf. When sitting on the floor he has to hold onto objects such as a chair to pull himself up. On examination, there is significant wasting of muscles in the shoulders, upper arms, and hips. There is significant weakness on muscle testing (i.e., the patient is unable to exert a normal force with muscle contraction). On…

How Does the Brain of a Dyslexic Person Function in Contrast to the Brain of a Non-Dyslexic Person? What is dyslexia? This question seems to be on repeat in my family’s conversations. Right now, my family is in the process of finding out if my seven year old sister has dyslexia. She has been to reading tutors and doctors but we cannot seem to figure out why she is struggling so much with reading. She is currently taking tests to determine if she has dyslexia. Since I am her overprotective sister…

the entire muscle but only a number of muscle fibres within a muscle. The entity motor neuron plus the power fibres it stimulates, is call a motor unit. The motor end plate (also known as the neuromuscular junction) is the seam of the motor neurons axon and the muscle fibres it stimulates. In précis the sliding thread hypothesis of power decrease can be out of order downward into four separate stage, these be; 1. Muscle commencement: The coast nerve stimulates an act potential (impulse)…

Are concussions a problem in football?

We can say that each part of the body is controlled by and connected to several many organs. Thus, many diseases and disorders in one organ can actually indicate the error in completely different organ or system. That brings us to this, The limbic system and Tinnitus. A person who has tinnitus is a person who is continuously hear noisy and annoying voices and…

Lambert-Eaton Myasthenic Syndrome (LEMS) is a rare, neuromuscular junction autoimmune disease. The immune system produces immunoglobulin G antibodies against voltage-gated calcium channels (VGCC) residing on the cell membrane of the presynaptic nerve ending.1,3,5,6 The etiology of LEMS is decreased exocytosis of the neurotransmitter acetylcholine from presynaptic neurons into the neuromuscular junction (NMJ) caused by autoantibodies attacking VGCCs.3,7.10 There are two distinct groups of LEMS…
