UNIT 6 - NERVOUS SYSTEM / SPECIAL SENSES
ACTIVITY – Diseases of the Central Nervous System A. This is the most common cause of crippling in children and results form prenatal, prenatal, or postnatal CNS damage due to anoxia. Motor impairment may me minimal or severely disabling. Associated defects, such as seizures, speech impairment, and mental retardation are common. This disorder cannot be cured but proper treatment can help the child reach his/her ful potential. The disorder is: _______________________________________________________ B. This is a condition of the brain that is marked by susceptibility to recurrent seizures that are associated with abnormal electrical discharges in the neurons of the brain. The causes are unknown, but may include birth trauma, infection, anoxia, and brain tumors. Treatment includes medication such as dilantin, Phenobarbital, and tegretol to control seizures. The disorder is: _______________________________________________________ C. In this disease, the covering(s) of the brain and spinal cord (usual y the pia mater) become inflamed, usual y the result of bacterial infection. Treatment includes early recognition and antibiotic therapy. Symptoms include a sore neck when the patient is lying down and the practitioner pul s the head forward and the patient flexes his hips and knees in response, fever, chil s, malaise, anorexia, and changes in the cerebrospinal fluid. The disease is: _______________________________________________________ D. This disease is sometimes referred to as the shaking palsy as involuntary tremors are one of the cardinal signs. It is one of the most crippling diseases in the United States, striking 1 in every 100 people. There is a dopamine (neurotransmitter) deficiency, which prevents brain cel s from performing their normal inhibition or stopping of nerve impulses within the CNS. Muscle rigidity may occur. The cause is unknown. Death usual y occurs 10 years after the disease is diagnosed. There is no cure for this disease. The primary aim of treatment is to relieve symptoms and keep the patient functional for as long as possible with the use of drugs and physical therapy. Stem cel research may be a promising venue for future medical care. Michael J. Fox, Janet Reno, Pope John Paul and Mohammed Ali both are afflicted with this disorder. The disorder is: _______________________________________________________ E. The cause of this disorder is unknown. There are progressive changes in the neurons of the brain due to a lack of neurotransmitters in the brain, trauma, and genetics. The onset is slow. In the beginning, the patient wil have very mild changes such as memory loss, forgetfulness, and difficulty learning new information, deterioration in personal hygiene and appearance, and an inability to concentrate. As the disorder progresses, personality changes may be seen. Physical disability progresses and death usual y results from infection. Stem cel research may be promising. Former President Ronal Reagan was afflicted with this disorder.
Unit Six- Nervous System / Special Senses
The disorder is: _______________________________________________________ F. This disease is the most common motor neuron disease of muscular atrophy. Onset occurs between the ages of 40 and 70. The causes of this disease include autoimmune disorders, disturbance in motor neuron enzyme metabolism, difficulty producing nucleic acids, severe stress, trauma, and physical exhaustion. The symptoms include muscle weakness, muscle atrophy, dysphasia, dysphagia, and dyspnea. Mental deterioration usual y does not occur, but depression is a common response to the disease process. Death usual y occurs within 2 to 5 years after diagnosis as there is no effective treatment available. The disease is: _______________________________________________________

Insect-Resist Treatments 0f Wool Carpets Larvae of some insects may eat wool and other animal fibres (mohair, cashmere etc) and they may cause damage to stored textiles and carpets. These insects (Clothes Moth, House Moth, and Carpet Beetle) are unique in their ability to live on wool, but are not restricted to this diet. They may feed on a wide variety of dry materials with a high protein
