Because of its liquid nature, it is able to seep through spaces once a vascular injury occurs. We usually see it as bruising of the skin, when trauma causes breakage in the thin-walled capillaries in the dermis. The bruising then recedes with time, and the skin goes back to its previous appearance as if nothing happened. The same may not be applicable to other organs, more notably the brain. Although there is no obvious bruising similar to that seen on the skin, brain hemorrhages present with more serious signs of paralysis or changes in the sensorium, as caused by the ischemia and neuronal death of the area in the brain that should have been perfused by the injured vessel. Soon, ischemia of some brain tissue results to irreversible neurologic dysfunction. Prompt management is thus needed before neurologic defects become permanent (Kumar et al., 2010).
The age of hemorrhage is important because it determines the management of intracranial hemorrhage, as will be discussed later. The stages of hematoma are based on the form of hemoglobin in RBCs. Initially, during the hyper-acute phase or hours after the development of the lesion, hematoma is made up of a liquid suspension of intact RBCs containing oxy- or deoxy-hemoglobin. If the blood came from an arterial source, which is the case in most non-traumatic etiologies such as aneurysm, approximately 95% of hemoglobin molecules are oxygenated. Later, water is resorbed by the brain tissue, resulting to a solidified aggregation of RBCs. As the blood ages further, the hemoglobin denatures from oxy- or deoxy- to met-hemoglobin. This transformation is dependent on the oxidation of ferrous (Fe+2) heme iron contained by oxy- and deoxyhemoglobin to ferric (Fe+3) state, turning the protein into ...Download file to see next pagesRead More

Lumbar spine

...The Lumbar Spine and Radiology June 22, The lumbar spine is the long part of the spinal column which allows the human body to bear weight as well as absorbing shocks (Bogduk, 2005, p. 5). This column is known as the vertebra, or vertebral body (Bogduk, 2005, p. 2). The vertebral body is made up of 24 vertebrae, which in turn are made up of cortical bone, pedicles, and laminae. The rest of the vertebral body consists of intervertebral discs, facet joints, and the ligamentum flavum (Bogduk, 2005, p. 5-10).

...of surgeries due to spinal curvature was the most memorable. I had to go through two major surgeries, a brain and spine surgery to address the chronic dilemma. My greatest fear then, aside from recovering from all the pain is the thought that I could no longer participate in any strenuous physical activities because I could become paralyzed if too much pressure was exerted inside my head. The doctor could not explain why I was still able to walk. The support from family, friends, and the spiritual strength due to my immense faith in God helped me through these adversities.

Brain vs Left Brain Learning

...Right Brain vs. Left Brain Learning Introduction: The brain is the most complex organ in a human body and various aspects of its function are still a topic of research and constant debate. However, many authorities agree that two hemispheres of the brain are capable of thinking in separate directions. The recent work of Roger Sperry in his research of “Split Brain Theory” has fascinated many researchers around the world. He received a Noble prize for his work in 1981. In his Nobel speech, he mentioned that the same individual is capable of exhibiting two distinct forms of mental approach and strategy, just like two different people depending on whether...

Brain

...Psychology What are two kinds of evidence that consciousness depends on a functioning brain? To start with, damage to the alerting areas of the brain, the brain stem and the midbrain, most likely can result to loss of consciousness. The first evidence is that consciousness cannot exist without the cortex working accordingly. Without this part, it would not be possible to comprehend speech, plan, move, solve problems, or express emotions. All these are aspects of consciousness. Second evidence is the brain stem. The hypothalamus is responsible for the sleep cycle; therefore, the suprachiasmatic nucleus controls the preoptic nucleus that induces sleep. By inhibiting the...
