Opening: Every day, our elbows are used a lot in many ways. Although elbows pain are not really serious, it can make you frustrating and make your activities more inconvenient. Body: How is the elbow designed? - The elbow, in essence, is a joint which is formed by the union of three major bones is supported by ligaments. Connected to the bones by tendons, muscles move those bones in several ways. The bones that create the elbow are included:  Humerus: This long bone extends from the shoulder…

Myositis Ossificans Myositis ossificans is a condition in which an area of bruised muscle turns into bone (calcifies). This can happen when a deep bruise (contusion) is not treated. A contusion is caused by bleeding under the skin. When this blood seeps into soft tissues, it can form a clot (hematoma) and the clot it may go through a process called calcification. This turns the clot into bone. Myositis ossificans is relatively common in the arm or thigh. CAUSES The cause of this condition…

movement to occur, because this causes the contraction in it. This contraction pulls on the corresponding bone at its insertion point. Stationary bone is called the point of origin for the skeletal muscle, while the one which moves is known as the point of insertion. This together movement in skeletal and muscular systems cause the body movements and actions. When the signal to relax is received, muscle moves back to its original position and so do the bones. Section C 1. Outline the…

tissue Comparing skeletal muscle and cardiac muscle tissue Common things between the structures of cardiac muscle and skeletal muscle The skeletal tissue and cardiac muscle tissue both are part of muscle tissue. The cells in cardiac muscle and skeletal muscle are made up of fibres. The fibres in both of these muscles are striated. The fibres in both of these tissue have a similar kind of shape and appearance. Differences between the structures of cardiac muscle and skeletal muscle The…

believe that we have only one type of muscle in our bodies that help us with all different types of tasks, however; not only do our bodies have different muscle types, they also contain different muscle fibers that are used for different activities. Skeletal muscle contain three types of muscle fibers: slow twitch, fast twitch oxidative, and fast twitch glycolytic. Most muscles in our bodies have different combinations of these muscle fibers, although our body recruits different muscle fibers…

Who is the Real Winner? The question of whether athletes are born or made has become the leading topic of athletic debate in the recent decade. Were esteemed athletes such as Michael Phelps, Usain Bolt, Lionel Messi, and Rory McIlroy born with gifted talent, or were they made elite athletes through hard work and the right nurturing?. Through the development of the human genome and the increasing research into genetics, many scientists and athletes have wondered if nature or nurture has more of…

Movements propagated by skeletal muscle both simple and complex also require interaction with nerve. The nerves and muscle work together to help us do out conscious task with ease. The purpose of this lab is to identify how changes in such variables will affect the properties of the muscle in a human flexor digitorium superficialis (FDS) and to extrapolate the nerve changes from a sciatic nerve of a frog. Neurons are excitable cells structural features such as dendrites, cell body and axon.…

between 12-30m/s which shows that it is associated with cold, fast pain and mechanical stimuli, this also shows that the fibre is small and myelinated. Fast pain is sharp and localized sensory information which is then transmitted to the central nervous system…

Alexandra Banales X explains Y The purpose of this experiment was to measure the tension, or force, produced by interacting filaments in a muscle fiber. In order to test this, a subject had three electrode disks located on their forearm. These disks were connected to a computer monitor which traced the EMG records and the Force trace of their muscle contraction. Data was observed while the subject changed their hand movement in different ways including wrist positions such as fully flexed,…
