Legs are an important part of human life. Humans use their legs in almost every aspect of their life. For athlete's, legs are also very important. One important muscle group of the leg includes the quadriceps muscles, otherwise known as the quadriceps femoris. The quadriceps are made out of four other different muscles, that all work towards a specific function for the body. Although it might not be one of the most important muscles, the quadriceps muscles are a very important leg muscle that…

The knee is made up of four main things: bones, cartilage, ligaments, and tendons. The knee is a ball in socket and the elbow is a relatively simple hinge joint which only allows flexion and extension. The radius is smaller of the two forearm bones and sits on the outside of the joint.As spoken about before the cruciate ligaments are made up of two types of ligaments, the anterior and the posterior. They are often referred to the ‘crucial’ ligaments because it is important that the help the knee…

available rods that are used to be implanted in the spine. Materials that are being implanted in the spine must be corrosion and fatigue resistance, and they must be compatible with the biochemical environment of each patient’s bone (Healthpointcapital, 2016). There are 270 bones in the human…

Your tibia is a very hard bone to break. Most broken tibias are caused by strong collisions, such as vehicle crashes, and sports injuries. In the majority of the cases involving a broken tibia, it is often very noticeable. Some symptoms include unbearable pain, inability to walk, deformity or instability of the leg, bone “tenting” the skin, bones protruding through the skin and the loss of feeling in the lower extremity in which the injury occurred. After the break of the tibia, you should seek…

The ACL prevents excessive twisting, straightening and bending of the knee and once these movements are beyond what the ACL can handle, tearing of the ACL ligament occurs. A ligament is a very strong band of connective tissue, which attaches the bones together. Athletes who participate in a high demanding sport such as basketball they are more than likely to injure their ACL as basketball consists of running, sudden stops, dodging and jumping. Stopping abruptly or changing direction rapidly…

Introduction The clavicle, also called the collarbone, is the long bone that connects your shoulder to your rib cage. You can feel your collarbone at the top of your shoulders and rib cage. A clavicle fracture is a broken clavicle. It is a common injury that can happen at any age. What are the causes? Common causes of a clavicle fracture include: A direct blow to your shoulder. A car accident. A fall, especially if you try to break your fall with an outstretched arm. What increases the risk? You…

will help break down the bone and release the calcium from the bones to the blood stream. While it will also activate vitamin D which will help increase the absorption of calcium from the kidneys and intestines. Therefore, the body will keep the calcium in the blood instead of throwing it out through urine or stool. If the case was the opposite and the blood calcium level was too high, then the thyroid gland will produce calcitonin a hormone that helps build the bones by releasing…

Meniscus Tear A meniscus tear is a knee injury in which a piece of the meniscus is torn. The meniscus is a thick, rubbery, wedge-shaped cartilage in the knee. Two menisci are located in each knee. They sit between the upper bone (femur) and lower bone (tibia) that make up the knee joint. Each meniscus acts as a shock absorber for the knee. A torn meniscus is one of the most common types of knee injuries. This injury can range from mild to severe. Surgery may be needed for a severe tear.…

between dentofacial complex as a whole and the position of hyoid bone in different Angle’s class malocclusion has intrigued and attracted many researchers. The hyoid bone is unique in that it has no bony articulation with any other bone but is instead suspended in the soft tissue via ligaments and muscles (Romanes et al 1983). Different muscles such as infra and suprahyoid muscles and genioglossus muscle influence the position of the hyoid bone (Gray H, 1954) (Yamaoka et al 2003). Brodie…

could occur during and after physical activities (depending on the severity). The pain associated with shin splints results from excessive amounts of force on the tissues attaching the shin bone to the muscles surrounding it. The excessive force causes the muscles to swell and increases the pressure against the bone, leading to pain and inflammation. New fitness programs can cause shin splints if you do not ease into them and do too much too soon because your muscles cannot adjust to the quick…
