activities. Our bones specifically are unique in nature; they reconstruct themselves in a process where cells called osteoblasts regulate bone formation while another pair of cells called osteoclasts regulate resorption of minerals such as calcium and vitamin D. Deterioration of the skeleton is due to enlarged bone weakening by osteoclasts and decreased bone development by osteoblasts, resulting as the diseases known as Osteoporosis. Osteoporosis affects millions of people and causes burdens to…

Many have asked, what is Osteoporosis? Who does it effect? And will it affect me? These are some questions that could be going through a lot of people's minds. But the first question a person may ask is, what is Osteoporosis? According to (HealthFinder) it is a medical condition, a bone disease that makes your bones weaker, and more likely to break. It is said, that anyone can get osteoporosis, and its a continuous disease. Its most common in older women, usually after 50. But age, is not the…

In Daniel Liberman’s book, The Story of the Human Body: Evolution, Health, and Disease, he writes about the entire history of the human body and how it has evolved from our ancestors. His main purpose in writing this books is to not only educate and inform about the history of the evolution of the human body and its possible future, but his goal is to help push society to change the way they live. The main theme of The Story of the Human Body: Evolution, Health, and Disease is the same as…

Our bones are constantly being removed and regenerated by osteoclasts and osteoblasts. (Rodan, 1998) On Earth, this process is well balanced but when we enter the space, that is a totally different story. In the weightless environment, the activity of osteoclasts increases, which means they break down the bones at a higher rate. At the meantime, osteoblasts which regenerate the bones are not consecutively active. Consequently, out bones keep diminishing without recovery…

The humerus is classed as a long bone and is located in the upper arm, connecting the shoulder to the elbow. The long bone as suggested by its name is long in structure, meaning they are considerably longer then they are wider. The structure for the humerus is typically similar to all structures of long bones, with a shaft, bone ends and membranes. Dyaphysis or the shaft of the humerus makes up the long axis of he bone and is constructed of very high density compact bone (Merieb, 2010). This…

Scott et al. compared those who suffer from spinal cord injury (SCI) and the body under microgravity. Their findings show that SCI patients and astronauts, in long term conditions, have similar physiological outcomes and those who have SCI can be good examples to study the effects of spaceflight on the human body. The importance of comparing and contrasting these two populations is to be able to see if scientists can test individuals of one group to come up with results and conclusions of how to…

The Sci-Fi story I will be writing about is going to be about space mission to a habitable extrasolar planet. It will be based centuries into the future when technology has improved to the point that our human race can visit planets light years away. Of course there are still effects of long-term space travel on the human body, but the technology and research will be more advanced during the time period of my story. The mission is going to consist of highly trained astronauts and the most…

Dancing: A World Wide Sport If you’re a dancer, you’ve had people ask you what sport you play. Obviously you respond by saying, “I’m in dance.” Or, you hear people state that dance is not a sport. That just trips your trigger. You automatically want to defend yourself, but you don’t know what to say. I’m here today to help you defend the world of dancers! There are multiple reasons why dance is a sport but here a few of my favorites, you have less of a chance to get osteoporosis, it helps…

bone more rapidly than it will break down old bone, but as you age, this process slows. Your body beings to break down bone more quickly than it produces new bone, resulting in the weakness of bones. Your osteoclasts are overactive whereas your osteoblasts are under active. It is for this reason that it is found to be more common in men and women above the age of 50 due to the slowing rate of bone production within the body. Osteoporosis is often referred to as a silent disease due to the lack…

Context Bone scans are used to detect abnormalities in the bone due to its uptake in osteoblasts (Ka kit, W. and Morand, P. 2013). Patients who have bone scans are instructed not to adjust their diet prior to having a bone scan. Patients who are already booked for bone scans can be given supplements prior to their scan date and then scanned. Normal bone scans as well as scans of patients who had been on bone supplements which are of a similar body habitus will be given to radiologists who won’t…
