The Lovely Bones

that surrounds and deepens the cavity of the Glenoid. The labrum allows for full range of motion, stability, and cushioning in the shoulder. It is attached to the edge of the shoulder socket and supports the ball of the joint -or the head of the arm bone, known as the humerus- in order to stay in place. When the fibrocartilage of the labrum is torn, it is considered a labral tear. There are three common labral tears; Posterior labral tears, Superior labral tear from anterior to posterior (SLAP…

development. During development, the fetal bones are made up of cartilaginous tissue, which is like osseous tissue, except it is more flexible. The absence of calcium salts in its intercellular spaces makes it less dense. As development continues, the process of the depositing of calcium salts into the cartilaginous tissue occurs, and continues throughout their life. Ossification is the gradual replacement of cartilage and its intercellular substance by bone cells that are immature, and calcium…

“What is it?” In response to the question, Henry Morris thoroughly looked over the new discovery of his ten year old son, Jacob Morris. After Henry’s close examination, he set down the object on the wooden table and answered. “It is a buffalo’s jaw bone.” Jacob Morris lived in a quaint log cabin with his pa, Henry, and his ma, Katherine, in eastern Montana. Though not yet admitted into the Union, Montana saw many settlers, who made the treacherous journey across the rugged plains of the…

1. INTRODUCTION OSHA defines musculoskeletal disorders as “Injuries and disorders of the muscles, nerves, tendons, ligaments, joints, cartilage, and spinal disk”. According to OSHA, the MSDs listed as: Carpel tunnel, Rotator cuff syndrome, De Quervain, Trigger finder, tarsal syndrome, Sciatica, Epicondylites, and Tendonitis. Most of the work related MSD’s are developed over time and are caused by the work itself or the working environment of the employees. These are also possible to occur from…

Introduction: In 1951, Miller HM et al, first reported dental autotransplantation or autogenous tooth transplantation (1). Autogenous Tooth Transplant is defined as the transplantation of teeth from one site to another in the same person (2). The recipient site is either immediate extracted tooth socket or a surgically prepared alveolus. When there is an available donor tooth, ATT is a viable treatment option for replacement of a traumatized tooth (3). According to Mejare B et al, Molar…

Abstract: Dens evaginatus is an uncommon developmental anomaly of human dentition characterized by the presence of tubercle on the occlusal surface of mandibular premolars and lingual surface of anterior teeth. Due to occlusal trauma this tubercle tends to fracture thus exposing the pathway to the pulp chamber of teeth. This case report is about the presentation of dens evaginatus in mandibular premolars bilaterally, among them tooth 44 was associated with chronic apical periodontitis. Fractured…

is not a single joint but a complex arrangement of bones, ligaments and musculotendinous units that called the shoulder girdle. The primary role of the shoulder girdle is to provide a tremendous range of motion for positioning the upper extremity in space. The shoulder girdle also provides power and support for the upper extremity throughout and at the extremes of the range of motion. (19) The shoulder girdle includes three bones (scapula, clavicle, and proximal humerus), three…

The Process of the Skeletal System The human body consists of around 300 bones at birth, but as the body grows, the bones shrivel up and decrease to 206 bones. Those 206 bones form the skeletal system. Each bone varies in shape and size. The skeletal system is much more than framework for the body. The skeletal system has many functions. The skeletal system is composed of dynamic living tissues and it interacts with all of the other organ systems. The skeletal system even remodels its self.…

After going back to the doctor with a same complain, X-ray and some blood work was done to fine the cause of the hip pain. The doctor found that Bill’s X-ray is sowing abnormality in his right thighbone which shows osteonecrosis, which means that the bone tissue has stopped working (is dead) due to lack of blood supply. Bill was asked if he had experienced any trauma in the…

The first phase is the growth of a rib primordium that turns into a rib bone during its embryotic development. The second phase, which differs from most land vertebrates, is the development of a “shelf of bone” above the shaft of the rib bone to form the unique T-shape. The final phase is the development of its teardrop-like shape, which is caused by the widening of the lower ridge of the ribs, which also…
