    Contentious Bones a Case Study on the Skeletal System Wh Cliff and Aw Wright

    Your 80 year-old great aunt, Persis, was placing a canning jar on the top shelf of her pantry when she stepped awkwardly off the stool and twisted her leg at the hip. She felt a sharp pain in her hip and, after collapsing to the floor, found she could no longer stand. She was taken to the emergency room where an X ray showed that the neck of her femur was fractured. More detailed X ray images revealed reduced bone mass in the head and neck regions of the injured femur, in the ends of other long bones of the body and in the vertebrae. Surgery was necessary to repair the fractured femur and a biopsy of the bone tissue indicated that the composition of the osteoid was normal. Healing of the fractured femur is proceeding slowly.…

    Skeletal Human Anatomy Current Event

    Some molecular and cellular geneticists at the Baylor College of Medicine have discovered that Notch1, a gene that can decide cellular fate, can cause osteoblasts (cells that lead to bone formation) to become cancerous. They determined this data using a mouse model of osteogenic sarcoma, a deadly bone malignancy. Turns out that in mice, Notch 1 intracellular domain induces bone tumors 100% penetrance, and it seems as though osteosarcoma in mice initiated by Notch activation mimics the human disease. Dr. Brendan Lee, the corresponding author of the report, says that "This is the first example of Notch1 driving this type of cancer. Our study supports the hypothesis that Notch activating mutations can act as a common triggering mechanism in cells of mesenchymal origin such as committed osteoblasts. This is an unusual cancer that affects mainly the young and adults over 40. Treatment, once the disease has metastasized is only about 50 percent successful.” The results of the study showed that expression of the NICD in immature osteoblasts was sufficient to drive the formation of bone tumors, including osteogenic sarcoma, with complete penetrance. These tumors were shown to display features of human osteogenic sarcoma, specifically histopathology, cytogenetic complexity, and metastatic potential. Their studies in the mouse found that osteoblasts, the predecessor to the formation of bone and other bone-related cells, can be cells in which osteogenic sarcoma begins. Most importantly, this mouse model reveals osteoblasts as the potential sources of osteogenic sarcoma. This clinical trial opens many doors to anyone that has a form of osteogenic sarcoma, because knowledge of what accelerates the cancer at the molecular level can assist in the identification of other targets that could augment…

    Analysis Of Ray Bradbury's Skeleton In My Body

    Skeleton in My Body by Ray Bradbury & Leaping Poetry by Robert Bly is about people being bones and brains or rather mind and body. This is the cycle of life: spirit and body. Conception, birth, toddler, childhood, adolescence, coming of age and adulthood is what makes us who we are. Humans have 3 types of brains: reptilian, mammalian, and nonmammalian. Each one has a special job and some parts will be stronger than others, depending who you are.…
