Endochondral ossification and long bone growth in humans Endochondral ossification is the process in which the embryonic cartilaginous model of most bones, which supplies the longitudinal growth and is slowly replaced by bone. Endochondral ossification allows a growing bone to bare weight during its development. The endochondral process of ossification provides a framework for a more rigid skeletal material. Long bones of the limbs and ribs develop by endochondral ossification. Characteristics of
Pathophysiology: Increased bone resorption or decreased bone, aging because of decreasing supply of osteoblasts, estrogen deficiency, Calcium deficiency, Vitamin D deficiency, Bone fractures, Etiology: Low peak bone mass, being a women, smaller body frame size, lowered sex hormones, excess thyroid, low calcium intake, eating disorders, sedentary lifestyle, excessive alcohol consumption, tobacco use. Manifestations: Back pain, loss of height, stooped posture, bone fractures occur easily. Possible
bone markings. Bones are categorized as sutural, irregular, short, flat, long, and sesamoid bones based on their shape (Martini et al. 180). The long bones contain a diaphysis, epiphysis and metaphysis. The diaphysis in the long bone is made of compact bone which has a medullary cavity where marrow is kept. The epiphysis of a long bone is made of spongy bone is an open region of trabecula which
The forearm is a complex anatomical structure between the elbow and the wrist that serves an important function of the upper extremity. The forearm consists of two parallel bones, the radius and the ulna. It forms a functional unit that can be considered both as an axis and a non synovial joint (). This “joint” can be best understood in term of two “condyles”, the distal radio-ulnar joint (DRUJ) and the proximal radioulnar joint (PRUJ) (). The capsule of the elbow joint and the annular ligament stabilize
INTRODUCTION Chondroblastoma is an uncommon benign tumor accounting for less than 1% of bone tumors. It mainly involves the epiphysis or epimetaphysis of long bones.(1) Chondroblastoma with secondary aneurysmal bone cyst is a rare entity and only 13 cases have been reported in the literature reviewed. Ours is a case of calcaneal chondroblastoma with secondary aneurysmal bone cyst. Only two cases of calcaneal chondroblastoma associated with secondary aneurysmal bone cyst (ABC) has been reported till
I am doing an assignment on anatomy and physiology. Specifically related to the musculoskeletal system. I am going to investigate the structure and function of different bones and a synovial joint in the body. I will show the relationship between the nervous and musculoskeletal systems. I intend to explore one disease of the musculoskeletal system and find out what it is like to live with said disease and found out how much people really know about it. What is anatomy and physiology? Anatomy:
The radiograph depicts Legg-Calvé-Perthes disease (LCPD) of the left hip. The right hip is not affected. This childhood hip disorder is a result of idiopathic avascular necrosis of the growing bony epiphysis of the femoral head, with boys affected four times more that girls (Texas Scottish Rite Hospital for Children, n.d.). This interruption in blood supply to the bone results in necrosis, and the femoral head become flattened due to weight and pressure placed on the bone during normal physical

Erlenmeyer flask deformity is an abnormality of the distal femur. Although rare, Erlenmeyer’s flask deformity can also be observed in other long bones, such as, the proximal ends of the humeri and tibiae and in the distal ends of the ulnae and radii. The deformity can occur on both sides of the body or on one side. The name “erlenmeyer flask” is gleaned from German chemist Richard Erlenmeyer’s laboratory flask that has a base shaped like a cone and a narrow, cylindrical neck joined by uncurved edges
A human’s body may appear to be a simple form, but nonetheless it is complex with trillions of living organisms working together to keep the individual alive and moving. Many of the composites that keep the individual movements are the cartilages, bones, and joints. Cartilage is divided into three classifications with the same function, but with their own specific functions as well. Bones, which protect the internal organs, are in many different categories based on the appearance of the bones.
There is a big international controversy if child labor is good or bad. Dating back to the late 1700’s, child labor has become a huge problem for the safety of children around the world. Children are missing out on the opportunity to learn and be educated because of forced child labor. Furthermore, the conditions that children work in are not safe and are very hazardous to their health and well being. Child labor is not as much of a problem in the United States however, it is a big problem in countries
Shinbone also called as tibia. Tibia is named for the Greek ‘’aulos’’ a flute that also know as tibia. Tibia is the most common fractured bone in our body and it is the second largest bone next to femur and commonly known as the strongest weight bearing bone of the body. Tibia is classified as a long bone and made out of diaphysis and epiphyses. The diaphysis is the midsection of the tibia while the epiphyses are the 2 rounded edge of the bone. The tibia gather its arterial blood supply from two
Explain the function of the heart and the structure of arteries, veins and capillaries. Referring to Louise Tucker 5th edition, the heart is an organ that pumps blood through the body via the circulatory system, supplying nutrients and oxygen to the tissues and removing carbon dioxide and other waste products. According to Louise Tucker arteries are thick walled, hollow tubes with a fibrous outer covering, a middle layer of muscle and elastic tissue. The functions of arteries are: • Carry oxygenated
Grave Site One DNA basics o DNA was extracted from powdered bone of each skeleton. Handled with extreme care since it could easily be contaminated. o Standard techniques for recovering DNA yielded only small amounts of DNA It was sufficient enough to try to do nucDNA testing using STR • Used to determine the sex of the skeleton o Showed that the three adolescent remains were female • Used to determine if the skeletons were related o Five of the nine were part of the same family group Nuclear
INTRODUCTION Fracture is defined as discontinuation of bone meaning the two bones is separated. The range of broken bones can be from a thin crack to a complete break. A crack (not only a break) in the bones is also known as fracture. It can be fracture of crosswise, lengthwise, in several places or into many pieces. Typically, it happens when the bone was subjected to impact of more force or pressure than it can withstand. Commonly, broken bone can happen in childhood and mature and late adulthood
Historical aspects of bone marrow study- A concise history The oldest known procedure carried out on mankind is that of trepanning. Skulls 8000–10,000 years old showing evidence of medical intervention have been found in Europe, Northern Africa, Asia and New Zealand (Fig 1). This extensive distribution has been attributed to Asiatic origins. Many of these ‘patients’ survived as shown by evidence of healing of their bones (Fig 1). In Peru, from where a large amount of information comes, the procedure
SCOLIODON The Chondrichthyes are also known as elasmobranchs. They are almost exclusively marine and include sharks, rays, and chimaeras. Scoliodon is an elasmobranch which is marine and is an active swimmer. Scoliodon is widely studied shark all over the world. The genus is represented by nine species, of which four are very common in Indian seas.It is commonly known as the Dog fish. Scoliodon was first discovered and described by Muller and Henle (1837). The genus Scoliodon is characterized by
