Cancellous bone

a disorder of bones that affects bones making them low in bone mass fragile and will lead to bone fracture. Bone fracture will easily occur as this disease cause the matrix inside the bone become weak and brittle.Bones can become so brittle due to activities such as coughing can cause fractures.According to Macgill (2015) the origin of the word osteoporosis explain the condition of ‘osteo’ is for bone and ‘porosis’ means porous that resulting in weakness. At this condition, the bone tissue is mineralized

Bone is made up of two types of structure which are the compact bone and the spongy bone. Compact bone lies over spongy bone and makes up most of a bone’s diaphysis, it consist of compactly arranged osteons which is the Harvesian system. Compact bone able to protect, supports and resist stress. Spongy bone makes up most of the mass short, flat and irregular bones and is also found at the epiphyses of long bones. It stores marrow and provides some support. The size of the bone grow throughout childhood

Endochondrial ossification is the term used for the development of new bone. Bone growth and remodelling takes place on a continual basis, ossification lengthens and thickens bone and therefore the process of ossification is used throughout life as well as during the period after bone fracture. Endochondral ossification, this type of bone development involves cartilage models, which are then replaced with bony tissue. This takes place at the embryonic stages; 8 weeks into development, condroblast

Bone Lit Review Introduction - Skeletal bone is a dynamic tissue structure that constantly undergoes changes and remodeling throughout someone’s lifespan. Skeletal bones is a mechanical support for locomotion and protecting the organs. Muscle tendons and ligaments insert onto the bone. It is only present in vertebrates. - Bone tissue is made up mainly of fibrous collagen connective tissue surrounded by a calcium phosphate-like mineral. It is hollow shaped structured that cannot swell or shrink

Bone grafts substitutes: A bone graft substitutes is a biocompatible material that used to promote a bone defects healing by providing a biologic response to the local site [45]. In orthopedic surgery, exposure to a severe injury commonly requires surgical intervention to compensate and repair the defected site. Bone grafts often need to replace the lost part principally in critical bone size defect, with which the reconstructive process will be enhanced by supporting the tissue growth. Replacement

(QCT) has also been developed to quantify bone mineral content and to assess bone loss (29). The main advantage of this technique is that cancellous bone can be exam¬ined separately from cortical bone (30). In particular, in QCT a thin transverse slice through the body is imaged: the image can be segmented to give a quantitative mea¬sure of volumetric BMD (unlike DXA) of vertebrae, as¬sessing the cancellous bone independently of surround¬ing cortical bone and possible aortic calcifications (31). QCT

Task 1 – Bones and Connective Tissue 1.1 Explain the structure and composition of bone tissue A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011). The epiphyses are the proximal and distal ends of a bone that consists mainly of spongy bone. (Tortora and Derrickson, 2011). Originally the epiphyses are separated from the diaphysis by a layer of cartilage that later fuses together

jaw or the jaw bone. (15) Sternum The sternum is a long flat bone located in the middle of the chest. (16) Intervertebral Disk An intervertebral disk is a pad of cartilage that fits between two vertebrae’s. (17) Ribs Ribs are a series of curved bones that are connected with the vertebrae and take place in pairs, humans have 12 on each side of the vertebrae body. Some of the pair are connected to the sternum and form the thoracic wall. (18) Sacrum The sacrum is a triangular bone that lies just

thin and is on the outside of the bone. It plays a vital role in growth and repair. It is divided into two sections, an outer layer and inner layer. The inner layer contains osteoblasts which helps with the increase of the width and length of other bone types. [13] Compact Bone/ Spongy Compact bones are also called cortical bone. Cortical bone is one of the two different bones found in the body. It is covered by periosteum and is lined with endosteum. These bones make up eighty percent of the human

to another bone. Those include but not limited to the legs, arms, and hands. The axial bones are located within the center of the body like the spine and ribs. Bones in these two regions are classified into different shapes including long, short, irregular, and flat. Flat bones are found in the skull and ribs. The flat bones in the human body are flat and thin often curved. Short bones are the same size length wise and width wise. Those are found in the wrist and ankle. Irregular bone does not go
