Physical injuries from pressure change are of two general types: (1) blast injury and (2) the effects of too-rapid changes in the atmospheric pressure in the environment. There are a number of different types of fractures, including avulsion, comminuted, and hairline fractures. Concussion. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other Ankles represent the ability to receive pleasure. If the blast injury is transmitted through water, the victim is usually floating, and only that part of the body underwater is exposed. It is characterized by blistering and often considerable edema (swelling). When the entire body is exposed to low temperatures over a long period, the result can be alarming.

You are in the right place and time to meet your ambition. There are basically two forms of radiation: particulate, composed of very fast-moving particles (alpha and beta particles, neutrons, and deuterons), and electromagnetic radiation such as gamma rays and X-rays. Because the nerve endings are destroyed in such burns, the wound is surprisingly painless in the areas of worst involvement. Radiation can result in both beneficial and dangerous biological effects. It must be emphasized that exposure to electricity can be harmful only if there is a contact point of entry and a discharge point through which the current leaves the body. Substance abuse disorders. – very hot or cold conditions. Using poorly maintained sports equipment, such as ski bindings that aren't adjusted properly Physical agents capable of causing cell injury include mechanical trauma, extremes of temperature (burns and deep cold), sudden changes in atmospheric pressure, radiation, and electric shock. Loss of fluid and electrolytes and infection associated with loss of skin provide the major causes of burn mortality. The threat of organisational restructures, mergers and redundancies can take its toll … At first blood is diverted from the skin to deeper areas of the body, resulting in anoxia (lack of oxygen) and damage to the skin and the tissues under the skin, including the walls of the small vessels. The major causes of physical injuries were from slips trips and falls and hitting objects with part of the body or against objects during the process of managing non compliant prisoners. Heat causes dehydration. Tissue A first-degree burn is the least destructive and affects the most superficial layer of skin, the epidermis.

However, as is the case in drug therapy, radiation treatment is a two-edged sword with both positive and negative aspects. Fear of life. The goal of radiation therapy of tumours is to deliver a dosage to the tumours that is sufficient to destroy the cancer cells without too severely injuring the normal cells in the pathway of the radiation. Anorexia: Denying the self life. Impact injuries are common in invasion sports. From a biological point of view, the most important attribute of radiant energy is its ability to cause ionization—to form positively or negatively charged particles in the body tissues that it encounters, thereby altering and, in some cases, damaging the chemical composition of the cells. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. When the exposure is prolonged, it leads eventually to cooling of the blood itself.

They do not necessarily have to appear immediately after occurrence of the injury. Ring in the new year with a Britannica Membership, Maintenance of the integrity of skin and mucosal linings, Interrelationship of defensive mechanisms, Immune responses in the absence of infection, radiation: Biologic effects of ionizing radiation. Physical injury of unknown cause must be reported to the local SPD office, or the local AAA, as suspected abuse, unless an immediate facility investigation reasonably concludes and documents that the physical injury is not the result of abuse.. The top three leading causes of work-related injuries – overexertion and bodily reaction, slips, trips and falls, and contact with objects and equipment – account for more than 84% of all nonfatal injuries involving days away from work.

Signs, symptoms and treatment of sports injuries, Home Economics: Food and Nutrition (CCEA). And some specific pathologies (things that can be diagnosed, and in some cases treated) A patient had sciatica-like leg pain for thirty-five years and was misdiagnosed many times until finally getting not only a definitive diagnosis but a cure.12 He had A physical injury is obvious, we can look at the broken bone or the blood. Ankle: Inflexibility and guilt. In low-voltage currents, such as are more likely to be encountered in accidental exposure to house or industrial currents, death is more often due to the stimulation of nerve pathways that cause sustained contractions of muscles and may in this way block respiration. Underwater divers, pilots of unpressurized aircraft, and persons who work underwater or below the surface of the Earth are subject to this disorder. In this category are the cells of the bone marrow, spleen, lymph nodes, sex glands, and lining of the stomach and intestines. Anxiety. Physical Agents • Physical agents capable of causing cell injury include mechanical trauma, extremes of temperature (burns and deep cold), sudden changes in atmospheric pressure, radiation, and electric shock 6. Mechanical trauma is an injury to any portion of the body from a blow, crush, cut, or penetrating wound. Burns may be divided into three categories depending on severity. the causes of injury are acts of violence against others or oneself, road trafﬁc crashes, burns, drowning, falls, and poisonings. Mood disorders. Any sudden trauma or change to our work-skills (such as a lay-off or job-transfer) can cause a sympathetic response in the form of pain, weakness or other distress to the hands. In effect the body is first violently squeezed and then suddenly overexpanded as the pressure waves move beyond the body. A third-degree burn is extremely serious; the entire thickness of the skin is destroyed, along with deeper structures such as muscles. Mechanical trauma is an injury to any portion of the body from a blow, crush, cut, or penetrating wound. A compound fracture is one that also causes injury to the overlying skin. If the body is well insulated against such passage, at the point of either entry or discharge, no current flows and no injury results. The complications of mechanical trauma are usually related to fracture, hemorrhage, and infection. A second-degree burn is a deeper and hence more severe injury. Overuse can cause the tendons to … Affected individuals suffer excruciating pain, principally in the muscles, which causes them to bend over in agony—hence the term “bends” used to describe this disorder. Cold causes hypothermia. These are the most common causes of a non-traumatic brain injury… Poor conditioning 4. What causes injury? Injuries occur in two ways: externally or internally. Traumatic brain injury usually results from a violent blow or jolt to the head or body. All the vital organs become affected, and death usually ensues. Slow internal bleeding may remain masked for days and lead to an eventual emergency. Art. Several factors predispose to frostbite, such as malnutrition leading to a loss of the fatty layer under the skin, lack of adequate clothing, and any type of insufficiency of the peripheral blood vessels, all of which increase the loss of body heat. An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury.Mild traumatic brain injury may affect your brain cells temporarily. All significant mechanical injuries must therefore be kept under observation for days or even weeks. If this occurs slowly, the gases diffuse into the bloodstream and are eventually expelled from the body; if this occurs too quickly, bubbles will form in the tissues and blood. The oxygen in these bubbles is rapidly dissolved, but the nitrogen, which is a significant component of air, is less soluble and persists as bubbles of gas that block small blood vessels.
