The death of Kaakutja: a case of perimortem weapon trauma in an Aboriginal man from north-western New South Wales, Australia, published by Cambridge University Press, delves into how biological anthropology was used to date the remains of an Aboriginal man and discover how he may of have died. The article first introduces the problem by explaining that a skeleton has been found in New South Wales that exhibits fatal trauma evidence. At first glance it would seem the fatal trauma is indicative…

Cardiovascular System Have you ever felt your heart racing before a big exam? How about after running a marathon? That fast, steady pace, making you breathe heavily. This is part of your cardiovascular system. A larger system made up of your heart system and circulatory system. The heart works to push out about 5 liters, on average, of blood every minute, to the organs, tissues and cells of the human body. This hard working organ, fully matured is only about the size of your clenched fist. Each…

human body contains of partially long bones, short bones, flat bones, irregular bones and sesamoid bones. Long bones, like their name, are the longest bones in the human body. Examples of some human bones that belong in this division are the femur, humerus and the tibia. In order for a bone to specifically be classified as a long bone, they must have a body that is longer than its width. Furthermore these bones must also have growth plates on either of the ends of the bone. As well as those…

This shows Onychonycteris finneyi, a bat fossil. The image shows its wing digits widely spread out with small claws on tip of each finger. It also shows the long tail found in earlier bat fossils (Moskowitz, 2008). Molecular Mechanisms The origins of bats wing muscles, molecular and cellular mechanisms are unknown but this research shows that the wing muscles of bats come from “a multiple myogenic source of different embryonic origins” (Tokita, Abe, && Suzuki, 2012). The results conclude that…

1. The hypothalamus is the processing centre that controls the body temperature in the brain, through temperature receptors the skin is able to realize changes to external temperatures which send the information to the brain (hypothalamus). There are also temperature receptors that identify the temperature changes in the blood. The Processing centre triggers for the effectors (these are the sweat glands and muscles) to adapt in order the make sure our body temperature stays at 37°C. If we…

Introduction The idea of the popular and continuously growing game of volleyball was thought of in 1895. The rules and skills started to evolve as the game grew more popular until it was an official Olympic sport in 1924. It started off with passing the ball back and forth until the three hit rule was developed. The game always started with a serve and as time went on, the serve became more and more complex. Different varieties and techniques of the serve started to emerge as the game grew.…

Introduction The repetitive nature of playing a musical instrument may cause a musician to experience discomfort, pain, or injury during the course of their life. This pain is often the result of repetitive movement or overuse of the tendons, nerves, and/or muscles referred to as a repetitive strain injury. One common repetitive strain injury is carpal tunnel syndrome, which occurs due to constant pressure and irritation of the carpal tunnel. For a serious musician, the occurrence of repetitive…

The patient was a 19 year old sophomore outside hitter in volleyball who sustained a right shoulder impingement her freshman year. Since this injury tends to have a gradual onset of symptoms, there was no specific mechanism of injury. However, the constant overhead movement of the arm during her hitting probably greatly contributed to her impingement. She saw the team physician last fall, but did not have any diagnostic imaging test completed such as X-ray or MRI. Although she did receive some…
