disorder is neurofibromatosis type one (NF1) (Reynolds, Browning, Nawroz, & Campbell, 2003). NF1 is estimated to affect approximately one in every 3,000 people (Reynolds, Browning, Nawroz, & Campbell, 2003). Since the mid 1900s, medical researchers, genetic scientists, and neuroscientists have been working to learn as much as possible about this disease. Etiology The etiology of NF1 has been thoroughly investigated and there is substantial knowledge on the topic. Neurofibromatosis type one is an
Neurofibromatosis My disorder research paper is about neurofibromatosis, which is a genetically-inherited disorder in which the nerve tissue grows tumors that may cause serious damage by compressing nerves and other tissues. The disorder affects all neural cells such as the Schwann cells and melanocytes. The melanocytes function abnormally in this disease, resulting to disordered skin pigmentation. The tumors would be able to cause bumps under the skin, colored spots, skeletal problems, and other
Neurofibromatosis Introduction Neurofibromatosis is a genetic disorder that causes tumors to form in the brain, spinal cord, and nerves. There are 3 types of this disorder. Type 1 usually appears in childhood, while type 2 and 3 appear in early adulthood. Type 3 can cause chronic pain throughout the body. Some cases may not require treatment other than careful observation. Other cases may require chemotherapy, radiation therapy, or surgery. In this essay i will explain the causes of the disorder
Marlene Cabanillas Duke Schoonmaker Biology 201 October 11, 2014 Schwannomatosis: A Newly Recognized Condition At an almost ironically small 1500 grams (3.3 pounds) the human brain is considered the “command center” of the human intelligence. With the help of the branching nerves, the brain has ability to interpret senses, to achieve the movement of the body and act as regulator of all behaviors; and that’s just a small fraction of the nervous systems responsibilities. As the Nervous System, the
about, but for me it’s always been a part of my life. By my first year in college I had already had seven different surgeries and already new that I would have more throughout my college career. My most memorable surgeries are the ones that I had on my lower back, two in total. One of them was when I was in high school and caused me to miss an entire year of gym class. Around the time of my second back surgery, I had started experiencing pain in my lower back again. This was nothing new to me since
spring was busy. We took a family vacation to Florida, and both of Kevin’s sisters were married. I went to a part-time status at the church because our lives were becoming increasingly busy, and my pastors agreed it was the best situation for all. Miranda and Micah were both in the weddings. Due to the diet and continued weight loss, Miranda was able to wear regular little girl dresses in the weddings. I was pleased. (Insert photo #15) Right after the last wedding, Micah had an appointment
parenchyma cells stimulate the formation of an abundant collagenous stroma, referred to as desmoplasia. Some tumours e.g. some cancers of breast are stony hard or scirrhous. Sarcomas have little connective tissue stroma and so are fleshy. Pseudo tumours: i) An ectopic rest of normal tissue is sometimes called a choristoma e.g a rest of adrenal cells under the kidney capsule or a pancreatic nodular rest in the mucosa of the small intestine may mimic neoplasm.
