Fibrodysplasia ossificans progressiva (FOP) or the stone man syndrome is a disorder in which the muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone. The extra skeletal bone formation causes the person loss of mobility as the joint become affected. Overtime the person affected with FOP has difficulty difficulties breathing, speaking, and eating. Due to their eating problem they may experience malnutrition. Signs and symptoms of FOP can be observed as…

A disease is an illness or sickness with specific, well-defined symptoms that affects a person, plant or animal. One disease in particular that affects at least 25,000 people every year in the United States is osteogenesis imperfecta. Osteogenesis imperfecta, or more commonly known as “brittle bone disease” is a rare genetic disorder characterized by bones that break easily generally from little or no apparent cause. Although some cases of osteogenesis imperfecta (OI) are not as severe as…

There are measures that can be taken to reduce the chances of tearing an ACL. Proper training techniques can help change how quickly your muscles contract. This then keeps the ACL from being strained (Benedetti). It is especially important for women to perform these exercises as women are eight times more likely than men to tear an ACL (Lee, Yun, and Marty Munson.). Many medical professionals believe this to be due to women having less muscles surrounding their knees than men and because women…

of the Kaibab Plateau for the dear at the beginning was about 45,000. ‘ Once the population passed K it would not be able to sustain itself. This is due to an imbalance in the ecosystem. An increase in deer population would cause a decrease in the grasses, shrubs, and trees. This would cause the deer to eventually die out because there will not be enough food to sustain the high deer population. The deer population had the highest reproductive growth rate between 1920 and 1923. In 1905 the…

Expanding-Early Expanding Pyramids have high birth rates, but also have high death rates. The entire population represented doesn’t seem like they have long life expectancies. Stable- Stable Pyramids represent developed countries. This pyramid has moderate or stable population increases, but has declining birth and death rates. The population has higher life expectancies, which has more of an older population. Contracting- Contracting Pyramids represents developed countries. This Pyramid is…

biologists define evolution? Biologists define evolution as the cumulative genetic changes that occur in a population of organisms over time. 2. What are Darwin’s four premises of evolution by natural selection? 1. High Productive Capacity- Each species produce more offspring than will survive to maturity. 2. Heritable Variation- Individuals vary in traits that may impact survival. 3. Limits on Population Growth, or a Struggle For Existence- Outside pressure on which individuals will survive.…

1. What is FOP? Fibrodysplasia Ossificans Progressiva is a rare genetic disease in which a person’s bones will begin to form into the muscles, tendons, ligaments, joints and connective tissues. Overtime the development will restrict a person’s movement. It has been described as turning a person into stone because their body is essentially encased by a second skeleton. 2. What are the initial symptoms? Symptoms of Fibrodysplasia Ossificans Progressiva, include: an infant being born with short,…

loss (Taylor, 2009). “Over time, the risk of osteoporosis and fracture increases as older women lose more one than they replace” (Taylor, 2009). The removal of both ovaries, called bilateral oophorectomy, may also cause osteoporosis and low bone density in women. “In one study, this surgery caused a 54% increase in hip, spine, and wrist fractures in postmenopausal women” (Taylor, 2009). Another possible cause of osteoporosis is low testosterone in men. “Men need both testosterone and estrogen…

Osteomyelitis Anoimalo S. Matagi Alaska Career College Abstract Osteomyelitis affects about two out of every 10,000 people (Cleveland Clinic, 2016). A possible reason as to why two of 10,000 people are affected is their lack of understanding to how to treat and prevent osteomyelitis. For example, those who are not aware of how osteomyelitis and how it effects the bone, as many organisms (most commonly staphylococcus) travel through the blood stream and can cause a bone…

There are many different forms of dwarfism found all over the world. The most common one however; is called Achondroplasia. Achondroplasia actually means “without cartilage formation”. This does not mean that the body cannot make cartilage. It means that the cartilage is not able to convert into bone. This process is called ossification. Achondroplasia is very similar to another type of dwarfism called hypochondroplasia. The biggest difference between the two is that your features are…
