Skull and Bones

During the fetal development the first stage of the “bones” is cartilage which resembles bones but is more flexible due to the lack of calcium salts as it develops calcium salts are deposit into it all through until after it is born to life. As a result, the process of gradual replacement of immature bone cells and calcium deposits is called Ossification. 2. What are the roles of Osteoclasts in bone formation? The roles of Osteoclasts in bone formation are as follows, the suffix –clast is from…

is the breakdown of bone in an abnormal fashion, which then leads to bone forming abnormally. Bones naturally break down and new tissue is formed, this is called renewal. The disease disrupts the renewal process, and creates abnormalities. The abnormalities usually include enlargement and weakening of bones. The symptoms of this disease include many things, and the most reported symptom is bone pain. Other symptoms include joint stiffness, visible deformities of the bones, bones easily fracture,…

Intramembranous bone formation, also known as ossification, is how flat bones develop from mesenchyme tissue. In this method of bone formation, there are four major steps in the developing process. In the first step, the ossification center forms by osteoblasts. These osteoblasts are created from stem cells within the mesenchyme that specialize. In the second step the osteoblasts from the ossification center produce proteins make up the osteoid. After the osteoid if formed it will combine with…

Achondroplasia Achondroplasia, also known as dwarfism, is a condition that causes abnormal bone growth and development. The condition is present at birth, and most people with achondroplasia will not grow to an average adult height. Achondroplasia affects the skull, spine, and bones in the arms and legs. Soft parts of bone, called cartilage, that would normally develop into hard bone do not change. This causes bones to be short and poorly shaped. Achondroplasia affects boys and girls equally.…

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…

therapy. Estrogen helps preserve bone mass by inhibiting bone dissolving action of the osteoclast. However, Susan is also active and exercises regularly, so she is less likely to have osteoporosis. Other factors such as bone cancer could have led to the weakening of her bones. 2.) If Susan had bone cancer, the CT scan would reveal the presence of a tumor. The densitometry scan would also show a change in the density of the bone due to cancer. 3.) Vitamin D helps the bones to absorb more…

cavities of the skull is an important part of the head and its function is essential to perform different activities. The ears are one of the structures responsible for the senses also located in the head. The head has various anatomical components. The skull is the structure which main function is to protect the brain; it is made up of the bones of the cranium and the face. Muscles and skin cover these bones, and this cover is called the scalp. Fourteen bones in the anterior region of the skull…

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…

Types of Bones According to the shapes of the bones and their structure, bones can be classified accordingly. The main 5 types of bones (in terms of their shape) are listed together with brief descriptions and examples of each. 1. Long Bones 2. Short Bones 3. Flat Bones 4. Irregular Bones 5. Sesamoid Bones Bone types (Classified by shape) Description Example(s) 1. Long Bones "Long bones" are longer than they are wide. They consist of a shaft and are generally curved. • Femur (leg bone) •…
