Bones & Muscles
Bones in our body are living tissue. They have their own blood vessels and are made of living cells, which help them to grow and to repair themselves. Every single person has a skeleton made up of many bones. These bones give your body structure, let you move in many ways, protect your internal organs, and more.
As well, proteins, minerals and vitamins make up the bone. Bones have several parts, but are manily made out of calcium deposits. It takes around 20 years for our bones to completely harden. The building of bones happens throughtout our lives. We are born with about 300 soft bones. During childhood and adolescence, the cartilage grows and is slowly replaced by hard bone. Some of these bones later fuse together, so that the adult skeleton has 206 bones. Bones are composed of two types of tissue. 1. A hard outer layer called cortical (compact) bone, which is strong, dense and tough.
2. A spongy inner layer called trabecular (cancellous) bone. This network of trabeculae is lighter and less dense than compact bone.

Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.

Osteoporosis is a condition that causes weakening of the bones in your body. Also called "brittle bone disease," osteoporosis increases your chance of sustaining a broken bone. Broken bones can cause significant problems, especially when a spine fracture or broken hip occurs. Because of these concerns, all people should understand their chance of developing osteoporosis, and if they need steps to prevent the development or progression of osteoporosis.

Risk factors include

Getting older
Being small and thin
Having a family history of osteoporosis
Taking certain medicines
Being a white or Asian woman
Having osteopenia, which is low bone density

Osteoporosis is a silent

    They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and have a complex internal and external structure, are lightweight yet strong and hard, and serve multiple functions. One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue that gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.Compact (cortical) boneThe hard outer layer of bones is composed of compact bone tissue, so-called due to its minimal gaps and spaces. Its porosity is 5–30%.[6] This tissue gives bones their smooth, white, and solid appearance, and accounts for 80% of the total bone mass of an adult skeleton. Compact bone may also be referred to as dense bone.Trabecular (cancellous) boneFilling the interior of the bone is the trabecular bone tissue (an open cell porous network also called cancellous or spongy bone), which is composed of a network of rod- and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow. Trabecular bone accounts for the remaining 20% of total bone mass but has nearly ten…

    Your 80 year-old great aunt, Persis, was placing a canning jar on the top shelf of her pantry when she stepped awkwardly off the stool and twisted her leg at the hip. She felt a sharp pain in her hip and, after collapsing to the floor, found she could no longer stand. She was taken to the emergency room where an X ray showed that the neck of her femur was fractured. More detailed X ray images revealed reduced bone mass in the head and neck regions of the injured femur, in the ends of other long bones of the body and in the vertebrae. Surgery was necessary to repair the fractured femur and a biopsy of the bone tissue indicated that the composition of the osteoid was normal. Healing of the fractured femur is proceeding slowly.…

    There are on average 206 individual bones in an adult human skeleton, which are both metabolically active and highly vascularised. Bones have many important roles within the human body, for example they provide structure and support for the fleshy tissue, protection of vital organs eg the brain in the cranial cavity, storage for vital materials eg calcium and phosphorus and also enables movement of the body as the bones provide a surface for ligament, muscles and tendons to attach to. The bones also play a role in blood production of both white and red blood cells as bone marrow is stored in the central cavity of long bones. The 206 individual bones can be divided in to 5 subgroups of bone, these are;…

    The human body is amazing in so many different ways, but yet very complex. So many things are happening all at once. The human body is sustained by the skeleton which is composed of the three most important parts: bones, cartilage, and ligaments. The Skeletal System is composed of two-hundred and six bones. Each of the bones are connected to another bone by ligaments and or tendons. Ligaments are a strong, flexible, and fibrous tissue that connects two bones or cartilages or holds together a…

    Ossification is the process by which bones are formed and there are two types of bone formations. According to our Wiley textbook “Intramembranous ossification, one of the types of bone formations, happens when osseous tissue forms directly within mesenchyme arranged in sheet like layers that resemble membranes. In the second method, endochondral ossification, osseous tissue forms within hyaline cartilage that develops from mesenchyme.” Intramembranous being the simplest type of bone formation.…

    Osteoporosis is a bone disease that can get worse with time. Your bones become fragile due to losing bone mineral density and bone mass. People do not realize this disease is occurring because they cannot feel their bones becoming weaker ("What is osteoporosis," 2011). Osteoporosis is most likely caused by three imbalances in the human body. Cause number one is a low magnesium/high calcium ratio. Cause number two is your female/male hormone is low. Cause number three is a low thyroid function ("The causes of osteoporosis,").…

    Osteoporosis is a major cause for concern for many older aged women and is gaining prevalence as our population ages (Ong, Sahota, Tan & Marshall, 2014). Identifiable by a lower than healthy bone mass and bone tissue deterioration (Ong et al., 2014; Mehler, Cleary & Gaudiani, 2011), osteoporosis leads to an increased risk of fracture in those with the disease, which in turn leads to pain, fragile bones, high medical bills, a loss of independence, and potentially, a shortened life span (Aungst & Rainer, 2014). Thus, reducing the risk factors associated with osteoporosis is an important field of research. This being said, numerous studies are being conducted into the causes of osteoporosis and possible methods of prevention.…

    The bone breaks that happen from osteoporosis can occur from just minor falls, and in severe cases of osteoporosis, can occur from things as simple as sneezing, coughing and bumping into items such as furniture in the home (What Is Osteoporosis?). It is often hard to tell when osteoporosis first begins. Osteoporosis is often considered a “silent disease” because one cannot feel their bones getting weaker. Studies indicate common signs that are first noticed are decreasing height and the upper part of their backs beginning to curve. The decrease in their height and the curving of their backs occur when vertebrae in the back break or collapse (What Is Osteoporosis?). The longer the person lives with osteoporosis the more likely bone breaks will occur. The most common sites for fractures are in the hip, back, and wrist (Christodoulou & Cooper). Because the age range of of those with the greatest risk of developing osteoporosis are the elders, complications often arise when preforming the surgeries needed to fix the fractures. In some cases, these complications can lead to death (What Is Osteoporosis?). Progression is slow and can often go unnoticed until things go from bad to worse with one incident. Life-style changes can help diminish the frequency of fractures. Prevention, such as proper diet and regular exercise are the best options to prevent development of this crippling disease (Christodoulou & Cooper). The number one way to slow the progression of osteoporosis is to see a doctor and become familiar with the care needed to prevent…

    That means the person is born without protein or the ability to make any protein. OI then becomes the brittle bone disease that is seen in many children who have broken their bones multiple times without any real explanation. Another thing to look out for is the possibility of having a pathologic fracture (PF). That occurs when the bone is too thin. Other risk factors are smoking, excessive drinking, someone who is taking steroids, small frame, physical inactivity, and a poor diet with low calcium intake or lack of, elderly who live in institutions with little or no movement and not adequate source of calcium, and even post menopause. When it comes to ethnicity, Asians and Caucasians are more at risk and woman more than men are also at risk. When a woman is going through menopause, her estrogen levels are low. Immunosuppressive medication can trigger osteoporosis, which is a drug given to a transplant patient. This is to decrease the chance of the new transplant of being rejected by the body. The drug can be given to treat skin diseases, such as psoriasis. Other factors, thyroid medications that are taken in an excess of at least months can make someone susceptible to the body losing bone mass or density. If someone suffers from a fracture, that may require a hospital stay and for the doctors to run further…

    The Skeleton is made up of 206 bones. There are two sections in the skeleton, the axial skeleton and the appendicular skeleton. The axial skeleton supports the head, neck and torso, and the appendicular supports the limbs and attaches the limbs to the rest of the body. There are five types of bones in the body, short bones, long bones, flat bones, irregular bones, and sesamoid bones. The skeleton has many functions. It supports the body and gives the body its shape. It allows movement to occur. The skeleton protects delicate organs for example the ribs protect the heart and lungs. It allows joints to move by attaching to muscle. Bones are composed of osteoblasts and osteoclasts. There are two main types of bone tissue, compact and cancellous.…
