Bone marrow

using two different high-speed cameras, each using 2,000 frames per second. Pecking force was measured using a force/torque sensor that was implanted in the cages of these birds. Researchers specifically traced the bird’s abdomen, eyelid, cranial bone, and the tip of the beak using micro-CT scanning (Wang et al.,…

joint space narrowing. Grade III applies when there is significant arthrosis and architectural changes, with a variable degree of joint space narrowing. Finally, grade IV is reserved for gross articular destruction with extensive loss of subchondral bone. No such radiographic classification systems exist for primary OA or posttraumatic arthritis. However, there are typical radiographic findings for each disease. The radiographic characteristics of osteoarthritis include ulnotrochlear…

Human bones are crucial to aid body movement and stabilize joints. However, the ossification of bones where it shouldn’t be present can cause many difficulties in the body’s ability to perform natural movements. Fibrodysplasia Ossification Progressiva (FOP) is an extremely rare autosomal dominant disease in which the muscles, ligaments, and tendons progressively transform into bone (Kaplan, Nassau, & Shore, 2014). This formation of new bone forms outside the natural skeleton structure (See…

Open wound is a soft tissue injury in which skin is torn, cut or punctured caused by mechanical factor that damages the skin. It involve external or internal of the body tissue. Most open wounds are minor and can be treated at home. Firstly, there are many sign and symptom of open would which are bleeding excessively, inflammation on the skin, redness, tenderness, swelling, the skin become rough or decreasing the range of motion of the body parts. Secondly, open would is caused by several…

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…

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 .…
