Malfunctions and Disorders Nervous system Disorders Stroke: a neurological dysfunction caused by a loss of blood flow to a part or parts of the brain ** May be caused by an aneurism (popped blood vessel), embolism (blocked blood vessel), or thrombus (partly blocked blood vessel Meningitis: inflammation of the meninges that may be viral or bacterial ** (the meninges are tissue that surrounds the vertebrae and brain). Nervous System Disorders II Polio: an airborne (communicable or infectious) virus that destroys the function of motor neurons when it comes in contact with the central nervous system (causes paralysis) Cerebral Palsy: a group of non-infectious disorders that cause physical disabilities in human development Endocrine System disorders Goiter: enlargement of the thyroid gland due to an insufficient amount of iodine in thyroxin Diabetes: a metabolic or autoimmune disorder in which the body does not properly manufacture or utilize the hormone insulin. **Type I (juvenile) does not properly manufacture insulin because the immune system is destroying the beta cells of the pancreas (the cells that make insulin) **Type II (adult onset) does not properly utilize the insulin that is released by the pancreas beta cells Excretory System Disorders Gout: a build up of uric acid in the joints especially in the area of the foot. Kidney Stones: a solidification of minerals and salts dissolved in water to form urine. ** May form in the kidney or ureter Skeletal System Disorders Tendonitis: inflammation of the tendons that attach 2 bones together Arthritis: degenerative disease that affects the function of your joints. ** Rheumatoid arthritis is an autoimmune disorder where the body cells are attacking the body joints Immune System Disorders (Microorganism) Any –itis (usually bacterial in nature) Ex. Tonsilitis, pharyngitis, laryngitis… May be a disorder caused by fungus (ringworm, athletes foot and dandruff) May be a disorder caused by protists or parasites (malaria and tapeworm disease) Immune system disorders (virus causing) Retrovirus (HIV and AIDS) DNA viruses (Smallpox, Chickenpox, Herpes, and Epstein-Barr) **The Epstein-Barr virus causes mononucleosis RNA viruses (measles, mumps, rubella, flu, common cold, and polio) Immune system disorders (autoimmune diseases) Type I diabetes: insulin is not properly manufactured because the immune system attacks the beta cells that produce insulin Lupus: damages the skeletal, circulatory, respiratory, excretory, and nervous systems Multiple Sclerosis: damage to the cerebellum (loss of motor functions) Immune system (other) Cancer: and overproduction of cells that does not reproduce by typically following the cell cycle
