Femur, the bone of thigh, also known as os femoris, is the longest and strongest bone of human body. The head of the femur articulates with the acetabulum of hip bone forming the ball and socket variety of synovial joint-the hip joint, whereas the distal part of the femur articulates with the tibia and patella forming the knee joint. The anatomy of the proximal end of the femur, in recent years had received the much deserved attention because of the importance of early treatment of congenital…

calcium absorption, which can, in turn, cause bone diseases such as rickets or osteomalacia. (Nair, 2010, para. 4) Osteomalacia refers to a softening of bones that are often caused by a vitamin D deficiency which make bones more susceptible to bowing and fracturing. Osteomalacia is not the same as osteoporosis, osteomalacia results from a defect in the bone-building process, while osteoporosis develops due to a weakening of previously constructed bone. (Mayo clinic [Mayo Clinic Staff], 2014,…

The anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are located in the knee joint. Those ligaments are being connect the thigh bone which is also known as (femur) and the big bone of the decrease leg (tibia) on the knee joint. The ACL and PCL stabilizes the knee against the front-to-lower back or again-to-front forces with an "X" shape in the knee that . ("ACL (Anterior Cruciate Ligament) Injuries Guide:…

Image 10 compact bone tissue In an image, 10 compact bone tissues give support and structure to the body and permit movement. It also stores calcium and has blood-shaping cells. 2] It consists of osteons and Haversian system. The osteons has a canal which is encompassed by concentric rings of matrix. 1] There are four main types of tissues; epithelium, connective, nervous and muscle, inside of every tissue type, there are varieties present. In image 1, 2 and 3 are of epithelium tissues that…

In mammals, longitudinal bone growth occurs at the growth plate by endochondral bone formation. The growth plate consists of three principal zones: resting, proliferative, and hypertrophic. The resting zone lies adjacent to the epiphyseal bone and contains infrequently dividing chondrocytes. The proliferative zone contains replicating chondrocytes arranged in columns parallel to the long axis of the bone. The proliferative chondrocytes located farthest from the resting zone stop replicating and…

anti-proliferative activites has been studied in vitro; however its effects on osteoclast differentiation have not been demonstrated. In this study, CTXA was found to suppress RANKL-induced osteoclastogenesis, actin ring formation, and bone resorption in RAW 264.7 cell lines and mouse bone marrow monocytes (BMMs). CTXA significantly inhibited the JNK/mitogen-activated protein kinase (MAPK) signaling pathway without affecting ERK and p38 signaling in RANKL-stimulated RAW 264.7 cells and BMMs.…

discuss bones of the pectoral and pelvic girdles as well as their attached limbs associated with skeleton models found in your text. The pectoral griddle contains: 2 clavicle bones (known as collarbones that brace the scapula and arms making up the shoulder); and 2 scapula bones (known as the shoulder blades functioning as a stabilizer and provides movement of the shoulder). The attachments of the upper extremity from the pectoral area includes: 2 humerus (these are the largest and longest bones…

birth to adulthood, the amount of bones in the human body decreases as they are amalgamated together to construct larger and sturdier bones. Adults have two hundred and six bones in the body; On the other hand, babies are born with approximately three hundred bones. The axial skeleton consists of eighty bones, which are part of the skull, hyoid bone, vertebral column and thoracic cage. Additionally, the appendicular skeleton consists of one hundred and twenty six bones that are part of the…

ossi fi cation or bone formation). Remodeling involves continuous removal of discrete packets of old bone, replacement of these packets with newly synthesized proteinaceous matrix, and subsequent mineralization of the matrix to form new bone (FernándezTresguerres-Hernández-Gil et al. 2006; Fraher 1993) . These processes also control the reshaping or replacement of bone during growth and following injuries like fractures but also microdamage (prevents accumulation of bone microdamage…

Objectives Determining the age at death of a skeleton can be complicated and possibly difficult dependant on state of preservation, bones present, or archaeological context. By using measurements of the present long bones and the data that correlates the fusion times of the distal and proximal epiphyseal unions, an age at time of death can be narrowed down to a less broad range. While this measurement method is not completely accurate, dentition ageing techniques and cross referencing of the…
