Temporal bone

difference!! Bones remodel themselves in a lifelong process where mature bone tissue is removed by a process called bone reabsorption. A new bone is formed during ossification, or new bone formation. This controls the shaping, and repair of the bone after a fracture or injury. If there is an imbalance in these two processes, this can result in serious bone loss. My 98 year old grandmother has osteoporosis. This is a condition in which the bones are weakened due to a decrease in bone mass. It can…

Discussion: Bridges are affected by both internal and external forces. Internal forces occur within the bridge, through tension, compression, bending, etc. External forces are applied to the outside of the bridge, and can be static or dynamic. The static load of the bridge is the bridge itself, and the weight of its members and components. This is created by the force of gravity pulling on the members of the bridge. The dynamic load moves and changes, such as traffic, people, wind. It is created…

Question 1 Biceps brachii-found in the arm with two heads, and is parallel with the body. "At the point when a parallel muscle contracts, it abbreviates and gets bigger in measurement". Extensor digitorum-a lower arm muscle that develops the finger joints is uni-pennate. Flexor carpi Muscles-Allows the wrist to flex and snatch, it is a shaft muscle shape with a long ligament. Transversus abdominis-its umbrella molded and is for stance arrangement and is situated in the stomach. Rectus femoris-Is…

Intramembranous bone formation, also known as ossification, is how flat bones develop from mesenchyme tissue. In this method of bone formation, there are four major steps in the developing process. In the first step, the ossification center forms by osteoblasts. These osteoblasts are created from stem cells within the mesenchyme that specialize. In the second step the osteoblasts from the ossification center produce proteins make up the osteoid. After the osteoid if formed it will combine with…

Osteomyelitis is an infection of bone, bone marrow, and surrounding tissue. The condition can affect any age group but in different ways. Red bone marrow of long bones is typically targeted in children because yellow bone marrow replaces red bone marrow in adults (Bires, Kerr, & George, 2015). Adults usually are introduced to foreign organisms directly through trauma or surgery. Plain radiography, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, and ultrasound all…

presentation of the lower limb (figure 1) would be the posterior cruciate ligament (PCL). The presented picture shows the tibia being pushed back posteriorly. The PCL, within the knee joint, prevents posterior translation of the tibia bone related to the femur bone (Moore et., al, 2014). If the PCL is torn, then the tibia can move backward too much leading to instability of the knee. The knee joint serves as a hinge joint that connects the femur to the tibia allowing for flexion, extension,…

Acute back pain Introduction: Low back pain is a universal human experience -- almost everyone has it at some point. The lower back, which starts below the ribcage, is called the lumbar region. Pain here can be intense and is one of the top causes of missed work. Fortunately, low back pain often gets better on its own. When it doesn't, there are effective treatments Definition: lumbosacral region accompanied by contraction of the paraspinal muscles hence the expression muscles sprain or strain .…

therapy. Estrogen helps preserve bone mass by inhibiting bone dissolving action of the osteoclast. However, Susan is also active and exercises regularly, so she is less likely to have osteoporosis. Other factors such as bone cancer could have led to the weakening of her bones. 2.) If Susan had bone cancer, the CT scan would reveal the presence of a tumor. The densitometry scan would also show a change in the density of the bone due to cancer. 3.) Vitamin D helps the bones to absorb more…

Osteoporosis is also known as the thinning of bones. The medical definition is a disease which weaken the bones overtime.Osteoporosis can happen to anyone but many women are at a higher risk than men.;Especially women who are just getting through their menopause stage.Osteoporosis affects the body in many ways. For instance the bones are weak so you need to find ways to stay healthy and take care of yourself. It can be really easy to break a bone.Spinal problems is a huge issue when it comes to…

explained to me that bone requires a good blood supply and circulation to keep it healthy. Several factors contribute. Cavitations can happen naturally. The third molars (wisdom teeth) are an example. When the tooth erupts the jawbone around it dissolves to allow the tooth to surface. If the tooth is impacted, the bone will sometimes die and become infected. Due to the design of the channel for blood flow; the infection can actually block the blood supply from getting through. Bone marrow edema…
