Osteochondrodysplasia is a group of unusual hereditary disorders of the bone, connective tissue, or cartilage. In this disorder growth and evolution of cartilage, bone, and connective tissue are impaired. Osteochondrodysplasias can be passed down by the parent to the offspring. This disorder causes the skeleton to flourish abnormally and the results can lead to dwarfism. The chances in someone having osteochondrodysplasia is one in every 4000 to 5000 births. This disorder is not developed as…

Limbs and girdles are rings of bones that attach each limb pair to the axial, or central, part of the skeleton. The hands are attached at the wrist joints and the feet are attached at the ankle joints. The hand contains 27 bones divided into carpals, metacarpals, and phalanges. The foot contains 26 bones divided into tarsals, metatarsals, and phalanges. Who knew a hand and a foot individually have so many bones? Unlike scaffolding, which is the regrowth of bones, bones change all the time. They…

Osteoporosis is a medical condition in which the bones become brittle and fragile from loss of tissue. All bones in your body can be affected by this disease but there are a few bones that break more easy. The bones of the spine, hip, and wrist are most likely to break. Hip fractures can be especially dangerous in elderly people because of how long it takes to heal and on top of that, they can not move while they are in the healing process which can lead to blood clots. Osteoporosis occurs when…

Bone is the main structural component of the body. Bones protect the body, they are the framework of the body, and they make it where on is just not a blob on the floor. A lot of time when one gets cancer in the bones it is an advanced form of cancer that has spread from elsewhere in the body. This is called metastatic cancer.(cancer.org) Other types include cancers that start in blood cells of the bone marrow. True bone cancers start from tumors, and are called sarcomas. (cancer.org)…

Briefly identify and discuss bones of the appendicular and axial skeletons. • The axial skeleton consists of the following bones. The skull is made of: • There are 2 parietal bones that form the superior and lateral parts of the skull. • There are 2 temporal bones that form the inferolateral parts of the skull. • The frontal bone forms what we know as the forehead (Cancer 2016). • The occipital bone is posterior making up most of the base of the skull. • The ethmoid bone forms the anterior…

Got milk? Hopefully so because osteoporosis is the most common type of bone disease, affecting over 200 million people worldwide. It involves the loss of bone mass and mineral content which causes the bones to become fragile and brittle. This leads to a higher risk of fractures, or breaks and cracks, than in normal bone. Literally, the word “osteoporosis” translates to “porous bones,” and occurs when excessive bone is lost, inadequate bone is produced, or a combination of both. Living with…

Osteoporosis is a rare disease which causes bones to become weak and brittle its very popular with people over their 50’s it causes them to become hunched up.More than 50 percent of people over 50 have it.Any bone can break but the most popular to break are the wrist,hip and the spine,if you break one of these phones you can fracture yourself really bad. Osteoporosis has been around for more than 4000 years it been found on ancient mummies it was common with all the women that lived in that era…

In mammals, longitudinal bone growth occurs at the growth plate by endochondral bone formation. The growth plate consists of three principal zones: resting, proliferative, and hypertrophic. The resting zone lies adjacent to the epiphyseal bone and contains infrequently dividing chondrocytes. The proliferative zone contains replicating chondrocytes arranged in columns parallel to the long axis of the bone. The proliferative chondrocytes located farthest from the resting zone stop replicating and…

Many people have probably heard of osteoporosis, and may understand it to be something along the lines of weaken bones, but may not understand the significance. Osteoporosis is characterized by decreased amount of bone density, and this loss of bone density allows for bones to be much weaker and even break easily. To avoid osteoporosis in the elderly, it is recommended to take calcium and vitamin D supplements, because it is much harder for the elderly to exercise, get sunlight, or even to…

Osteosarcoma is a type of cancer that starts in the bones. Osteosarcoma develops in children as well as young adults in areas where bone grows quickly. Types of osteosarcoma can be determined by what shows up on an imaging test. The cancer can be classified as High-grade, Intermediate-grade, and Low-grade. High-grade osteosarcomas are the fastest growing osteosarcoma. When studied under a microscope, many cells dividing into new cells are observed. High-grade most often is seen in children. Some…
