Osteoporosis Vs Spongy

Our bone tissues are made of a much harder substance than the cartilage, but they can be worn away by friction. They are tough on the outside, but on the inside they have a sponge-like design that helps to reduce the weight while retaining strength. They are designed to maintain the body’s structure and support the body’s movement and are used to protect weaker tissues, such as the brain, lungs and heart.

Osteoporosis is marked by a decreased bone volume. Loss of spongy ("cancellous") bone is greater than

Compact bone forms the outer layer of the bone and spongy bone is surrounded by the compact bone. On close examination, the compact bone had thin lines of closely packed materials making it hard to compress, while the spongy bone appeared like a network and was soft to touch. This is because spongy bone are made up of thin cells (trabeculae) separated by spaces (lacunae). For color difference, compact bone is cream colored while spongy bone is reddish in color.

Osteoporosis, also known as porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue which leads to bone fragility and an increased risks of the hip, spine, and wrist. Both men and women are affected by this (although it affects women more) but it can be prevented and treated. In the United States, more than 40 million people either already have osteoporosis or at a high risk because of low bone mass.

Generally, bone can be classified into two categories according to its structure, cortical (compact) and trabecular (cancellous or spongy) bone. Cortical bone is stiff, with 5–10% porosity, and it makes up approximately 80% of skeletal bone, including cuboidal bones, flat bones, and the ends of long bones. Cortical bone is much denser, stiffer, and stronger than trabecular bone. The average strength of a compact human bone was 105 MPa in a longitudinal compression test, and was 131 MPa in a transversal compression test. In the same experiment, the average longitudinal strength in tension was 53 MPa [39]. In contrast, the porosity of trabecular bone is approximately 50–95%, which is higher than that of cortical bones. The surface area of the

The condition of osteoporosis is when the bone tissue of a human being weakens over time, which makes the bones thinner and more porous than a healthy bone. While the bones is getting thinner it is also becoming weaker that will lead to a reduced ability for the bone to endure the weight. The more it increases to get thinner it also sets a person to a high risk of a fracture resulting from falls and they are worst in the wrist, hip and the vertebrae. 2.

     Osteoporosis is a health ailment which causes bones to become so porous that they can break easily. Osteoporosis literally means 'porous bones'. The bones in our skeleton are made of a thick outer shell and a strong inner mesh filled with collagen [protein], calcium salts and other minerals. The inside looks like honeycomb, with blood vessels and bone marrow in the spaces between bone. Osteoporosis occurs when the holes between bone become bigger, making it fragile and liable to break easily. Osteoporosis usually affects the whole skeleton but it most commonly causes breaks or fractures to bone in the wrist, spine and hip.

The literal meaning of the word osteoporosis is “porous bone.” Osteoporosis is a type of disease of the bones, which is caused by the bones becoming weak from either losing bone or making too much bone (NOF, 2016). The holes that are already in the bone become larger creating porous bone. This means the bones are now less dense thus making them weaker (NOF, 2016). Bones are made up of the three components collagen, living bone cells, and calcium-phosphate mineral complexes. The peak of bone mass happens around age of 18-25 (Bones, 2016). According to the national osteoporosis fund, the more bone that a person has at the time of the bone peak then the less likely you are to get osteoporosis later in life (Bones, 2016). Healthy, strong bones are like the foundation for your body. If they are weak then your body suffers. Bone mass decreases as we get older causing osteoporosis, which can lead to breaking bones (Bones, 2016). Women are more susceptible to forming osteoporosis than men are. However, osteoporosis can be prevented or slowed down by exercise and taking care of the body early on.

Osteoporosis is a chronic condition which bones become weak and brittle. Decreased mass is what makes the bones weak. Hormonal changes, lack of calcium, or vitamin D can cause this disorder. This disorder is commonly defined as “porous bone.” When the bone is affected by Osteoporosis, the holes in the honeycomb structure becomes larger and the overall density is lower than usual, which is why the bone is more likely to break. Some of the signs and symptoms are back pain that is caused by a fractured or collapsed vertebra, loss of height over time, an incline posture, and a bone fracture that happens much more easily than expected. This disorder cannot be cured. Treatments for this are to get enough calcium and vitamin D. Medications can also

A condition in which bones become weak and brittle is called Osteoporosis. Osteoporosis means “porous bone.” Healthy bone looks like honeycomb, while osteoporosis has much larger holes or spacing. It can’t be cured but treatment might help. When there is an imbalance of new bone and old bone resorption. Osteoclasts dissolve the damaged or unwanted bone leaving tiny holes for the osteoblasts to fill with new bone. The body sometimes fails to grow enough new bone to replace the old bone. Poor nutrients and smoking are some risk factors. Also, not enough exercise may play a key role as well. Many people have no symptoms until they have a bone fracture or shrink in height. There are treatments like medications, healthy diets, weight- bearing exercises,

The University of Cambridge indicates that there are two types of bone in the human body: cortical, or compact, bone and cancellous bone, which is also known as spongy or trabecular bone. Cortical bone accounts for 80 percent of the body's bone mass. This type of bone forms a cylindrical shaft around the marrow in the central part of the bone. Cancellous bone makes up only 20 percent of the body's bone mass, but it has a much higher surface area because of its higher porosity and honeycomb structure, according to the University of

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 skeleton. The remainder is cancellous bone (spongy bone) it has a spongy appearance and is shaped like a cylinder. It is so hard that surgeons would have to use a saw to cut

Figure 2. Intramembranous Ossification. The mesenchymal cells give rise to a centre of ossification. The bone cells in the ossification centres proliferate rapidly and move outward until the whole structure slowly progresses into spongy and compact bones. This structure of spongy bone doesn’t arrange the cells into

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Bone tissue is a connective tissue with an abundant matrix of intercellular substances that encloses widely separated cells. The bone matrix is made up of an inorganic component known as mineral salts that hardens the bone, and an inorganic component – collagen fibres and an amorphous mixture called ground substance, which gives the bone its strength (Tortora, Grabowski 2001). There are three types of cells that can be found in the bone, they are osteoblasts, osteoclasts and osteocytes. Osteoblasts are the cells that synthesizes a specialized organic material called osteoid which is important in the build-up of mineralized bone, osteoclasts are relatively larger multi nucleate cells made up of mitochondria and lysosomes that are responsible for the continuous erosion of bones. Lastly the last cells found in the bone are osteocytes, these are adult osteoblast cells found in the lacunae that have been surrounded by mineralized matrix. (Thibodeau, Patton 2003).Osteocytes are responsible for maintaining metabolism within the bone such as the exchange of nutrients with the blood.
