Magnesium is needed for the metabolism of potassium and calcium and for the mobilization of calcium from bones. Phosphorus plays and important role in the development and maturation of the bone. Its chief role in bone resorption, mineralization and collagen synthesis makes it essential in calcium homeostasis (Michael's). Diseases and disorders of the skeletal system include leukemia, bursitis, osteoporosis, sprains, fractures, spina bifida, scurvy, arthritis, scoliosis, talipes equinovarus or clubfoot, tendonitis, kyphosis and poliomyelitis (Family Shock 2001). Leukemia is also called cancer of the blood where abnormally large numbers of white blood cells multiply at an uncontrolled manner so that they interfere with the body's production of red blood cells. The cause is still unknown. Bursitis is a painful condition, which most commonly affects the hips and the shoulders. The bursa is inflamed. The bursa consists of small fluid-filled bags, which lubricate surfaces so that muscles can move over bones. The inflammation usually results from over-activity of an arm or leg. Osteoporosis is a disease caused by the loss of bone tissue. The cancellous bone is drained of calcium, becomes thinner or disappears altogether. A sprain is an injury to a ligament or tissue, which covers a joint. Most sprains occur from sudden stretches or tissue tears of the ligaments. Sprains are often very painful. The injured part usually swells and becomes "black and blue." A fracture is a broken bone. Spina bifida is a spinal defect, which occurs right at birth. In this condition, the spinal cord does not form properly around the vertebrae so that the skin cannot form around it. The cause is an error in the development of the embryo, which occurs about a month from the start of pregnancy. The use of alcohol or certain medications, exposure to extreme heat, or genetic factors may be responsible for the defect. Scurvy is a disease caused by the lack of Vitamin C or Ascorbic Acid in the diet. There is poor wound healing. Bruises come easily and the mouth and gums become sore. The gums also bleed, the teeth loosen, appetite becomes poor, the...
Arthritis covers more than 100 diseases of the joints. All types involve pain, stiffness and swelling of the joints. Osteoarthritis is a degenerative joint disease, where the joint wears out. It occurs frequently in the elderly, but it can also develop when a joint is repetitiously injured. The most affected joints are those in the hands, hips, knees, lower back and neck. Scoliosis is described as a side-to-side curve of the spine, which becomes visible during adolescence. The cause is still unknown, but it affects girls more than boys. Talipes equinovarus or clubfoot is an abnormal condition of the foot, usually discovered or present at birth. The foot is bent downward and inward, so that the child or person can walk only on his toes, heels or on the outside of his feet. Tendinitis or rheumatism is the stiffness or pain in the muscles or the joints. Kyphosis or hunchback is a forward bending of the spine, caused by anything, which deforms the bones in the upper part of the spine. Diseases, which cause kyphosis, include tuberculosis, syphilis, and rheumatoid arthritis. And poliomyelitis or polio is a serious disease, caused by the polio virus. This virus usually attacks the nerve cells of the brain and the spinal cord and causes paralysis. At first, the sufferer shows only slight symptoms, such as fever, headache, sore throat, and vomiting, which disappear after a day (Family Shock).
Any brain injury is serious and Julie should not have continued the climb. Seeking immediate medical attention as soon as the injury occurred may have saved Julie's life. The severe headache and ringing in her ears is another sign that the bump on the head was not so light, but still consistent with a Grade 1 concussion. Although Julie did not lose consciousness, she still had the key signs of
Anatomy and Physiology of the Skeletal and Muscular SystemsIntroductionToday, human health is being threatened on multiple fronts and it is not surprising that there is growing interest in developing a better understanding about the human body�s various systems and the respective roles they play in maintaining good health. Some people may intuitively recognize the importance of the skeletal and muscular systems to human health, but far too few understand the
The efferent division of the peripheral nervous system carries out the motor commands that are sent from the central nervous system. These commands or signals are then sent directly through the nerve fibers of the peripheral nervous system to the target organs where they will then be signaled to perform the desired action (Martini, Nath, & Bartholomew, 380). The peripheral nervous system can be further broken down as being a
E. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying
However, all muscles are ultimately controlled by the central nervous system. Because the muscles are attached to the skeleton, all skeletal movements can be traced back to the central nervous system. The integumentary system is one of the body's primary interfaces with the outside world. Together with the sensory system, the integumentary system interact with the central nervous system by communicating its inputs. 3. Homeostasis is the body's state of
Health Care Informatics Expert Systems Expert systems are always computer applications that tend to combine computer equipment, special information and software so that they imitate reasoning and advice of expert human. Being a part of artificial intelligence they offer discipline-specific advice as well as explanation to their users. Artificial intelligence covers a broad field of several aspects of computer generated thought, on the other hand, expert systems focuses narrowly. The area where
