x-ray absorptiometry, they found that in the trabecular sites such as the femoral metaphysis, tibial metaphysis, and the L5-6 vertebrae but not in the cortical sites. Using bone histomorphometry, microscopic changes were then looked at specifically in the tibial metaphysis. They found that there was a narrowing in new formed bones using a calcium chelating agent that fluoresces green. They also found that there was a marked loss of calcified tissue with marrow expansion in the tibial secondary…

continuity of bone. Proximal is situated close to or nearest the point or attachment or origin to the trunk of the body. Diaphysis is the shaft or central part of a long bone. 2. The humerus is a long bone located in the upper arm. It is classified as a long bone because the bone is longer than it is wide. The occipital bone is located on the posterior inferior part of the skull. This bone is classified as a flat bone due to broad, flat, and thin shape. Lastly, the lumbar vertebral bone is…

cartilage, bones, tendons and ligaments. The skeletal system also functions as a means of providing mobility and a storage unit for minerals, fats and production of blood cells. There are different components that make up the skeleton. The skeleton is firm, yet flexible from its fibrous connective tissues filled with minerals all known as the bone, cartilage, tendons, joints, and ligaments. The bone is comprised of collagen and calcium phosphate, which contributes to the firmness of the bone.…

Osteoporosis Osteoporosis can be defined as the weakening of bones in the body. This makes the bones so fragile, that something as simple as a cough or a sneeze can cause a fracture to the bone. The fractures occur most in the wrist, spine, or hip. Osteoporosis can disable a person from daily activities that they are used to doing without the troubles of osteoporosis. Osteoporosis can occur in any person, man or woman, of any race. There are no exceptions or exemptions. Osteoporosis has…

Osteoporosis, otherwise known as porous bone, is characterized by a decrease in bone density as well as depreciation of bone tissue. Due to these conditions, there is an increased risk of bone breakages and fractures of the hip, spine, and the wrist. Both men and women are susceptible to osteoporosis; however, several preventative methods and treatments are currently out there. Here in the United States, approximately 40 million people are affected by the disease or have a higher susceptibility…

regulation. The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive. Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process…

consisting of two hundred and six bones, works to provide support, protection, and movement. Many can argue that the skeletal system is the most important system due to it’s complex framework of long bones, short bones, flat bones, etc… but sometimes, the skeletal system may not be able to perform to its fullest potential. A simple bone disorder can cause a large amount of chaos externally, as well as internally. Fibrous dysplasia, for instance, can weaken bones and eventually cause a fracture.…

rate of new bone made does not match the levels of bone being broken down. The condition is caused by a range of factors in which effects the levels of new bones made. There are a range of factors that cause Osteoporosis, these are Estrogen: If the level of estrogen drops then bone loss accelerates and can lead to Osteoporosis. Having both ovaries removed in a process known as bilateral oophorectomy, results in low bone density. In the case of males, testosterone is converted to bone-preserving…

Types of Bone Fractures  Avulsion • A muscle or ligament pulls on the bone, fracturing it  Comminuted • Bone is shattered into many pieces Compression • Generally occurs in the spongy bone of the spine, for example a portion of the vertebra in the spine may collapse due to osteoporosis Fracture Dislocation • A joint becomes dislocated, and one of the bones of the joint has a fracture Bone Fractures Cont.  Greenstick Fracture • Bone partly breaks on one side, but not…

The human knee joint is a diarthrosis, or synovial joint, made up of multiple different tissues that work together to provide function. Everything from the outer layer of the skin to the core of the bone is necessary for the joint to articulate properly. The most superficial layer of the knee is the skin, which is the largest organ of the human body and is made up of the epidermis and dermis, which in turn are made up of keratinized stratified squamous epithelium as well as dense, irregular…
