Bone tissue is the structural and supportive connective tissue of the body. Another name for it is the osseous tissue. The human body has 206 bones which all have different functions within the body. There are 126 bones in the appendicular skeleton which are arms, legs, and trunk. The axial skeleton has 80 bones which are the head and the vertebrate. The role of bones help moves the body and give it shape. Important functions of the bone are support, protection, movement, mineral and growth factor storage, blood cell formation, fat storage, and hormone production (Marieb, Hoehn pp. 175). Bones support the body and keep the organs in place. Without the support, we would not be able to move our limbs. Bones protect the softer parts of our body such as the skull protects the brain. With the movement of the bones, we are able to walk, carry heavy boxes, and any other activities we wish to do. The minerals that are needed are calcium and phosphate. Calcium increases blood supply and phosphate builds and repairs bones, help nerves function, and make muscles contract. Blood cell formation happens in the red marrow. The blood cell’s job is to transport oxygen becoming carbon dioxide into the lungs. …show more content…
Without enough, our body cannot shape enough of the hormone calcitriol. Additional factors are previous bone fractures after minor falls, being under or over weight, being a smoker, drinking a lot of alcohol, and other medical conditions. There are no symptoms for osteoporosis which is why it is called a “silent disease”. To diagnose osteoporosis, the person will feel severe pain described as sharp or dull. The pain usually stops after 4-6 weeks. Depending on how many times the bone has been fractured, the pain can be persistent. To check for healthy bones, there are bone mineral density tests. A bone density test determines if osteoporosis is
An osteoblast is a “baby” bone cell whose main job is to secrete osteoid which forms the hardened, or calcified, bone matrix. Osteocytes are formed from osteoblasts. Osteocytes are the mature bones cells that have been completely differentiated. They are found in the lacunae of hard bone and have a spider-like appearance due to their canaliculi. Osteoclasts are a different type of cell formed from the mesenchymal cells. These cells are not related to osteoblasts or osteocytes. Their job is to basically “eat” the bone to create cavities and other hallow spaces during bone remodeling. Finally, the cells form differentiate to form fibroblasts and fibrocytes. These fibroblasts and fibrocytes secrete and form the matrix for fibrous connective tissue which is an essential component of the
Osteoporosis is noticeable when there is a decrease in bone volume. The changes in the osteoporotic femur include:
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
But after the early stage, your bones may become weak. These signs include: back pain, shortness of breath, shrinkage in height and bad, irregular posture. Many people don’t start showing signs until they have broken a bone, such as a wrist bone or a hip bone. There are two different types of Osteoporosis. There is Juvenile Osteoporosis (which is very rare), it occurs in children that is due to medication or medical conditions. Premenopausal Osteoporosis which happens to older women before menopause. There are three different ways to check for Osteoporosis. The first one is a painless bone density scan called a dual energy X-ray absorptiometry (DXA) (Stang, 2016). The second one is a digital x-ray radiogrammetry (DXR), it is like the DXA but uses less technology. And the last one is ultrasounds. Ultrasound scans are also used to screen for osteoporosis but it is not able to get a good reading like the others, so this method isn’t used as often. If you break a bone the doctor will try these types of x-ray to see if it was caused by
Bones of the skeletal system serve as storage compartments for vital minerals like phosphorus and calcium. Excessive calcium in the blood is stored in bones. Calcium is released from the bones into the blood when there are deficient amounts of it in the blood.
Osteoporosis is a condition, in which bones are weak from deterioration, loss of bone mass, and quality bone strength. Osteoporosis usually triggers postmenopausal women (women who have not had their period for a whole year), or older men and women. Some risks both older men and women endure when experiencing osteoporosis are decreased calcium and bone fractures. These symptoms or effects can all be caused by weight loss, smoking, age, ethnicity, genetics, medications, bone structure, and certain diseases that can later on contribute to osteoporosis, such as rheumatoid arthritis. Osteoporosis may be prevented by going to drug therapy to stop alcoholism and smoking, a sufficient amount of calcium intake, and exercising such as jogging, walking, and aerobics.
More than 20 million people in the united states are affected by osteoporosis disease every year. Furthermore, Osteoporosis leads to about 1.5 million fractures in this country every year ("Celebrate World Osteoporosis Day, 2016). Osteoporosis is a common disease where people lose bone density faster than normal. This disease causes the bone to become weak and brittle which leads to fractures of the spine, hip, and wrist from a simple fall or even a sneeze or a cough. Osteoporosis usually does not have any symptoms and goes undetected until a fracture occurs. This silent disease can impact any gender, but it affects more women than men especially after menopause. Osteoporosis occurs when more
The skeletal system helps with endocrine regulation, protection, support, movement, calcium storage, and blood cell production. The skeletal system consists of 206 bones, in the adult human body, all of which are divided into two major divisions. One division, the axial skeleton made up from 80 bones, runs along the body’s midline and the other division, the appendicular skeleton which has 126 bones.
The Skeletal system performs vital functions; supports movement, protection, blood cell production, calcium storage and endocrine regulation. That enables the human body to survive.
Osteoporosis is a disease in which the bones become so weak and brittle that even a cough can cause enough stress on the bone that it will cause the bone to facture. The most commonly broken bones are the hip, wrist, and the spine. Although it affects men and women of all races, post-menopausal Caucasian and Asian women are more commonly affected than those of other ethnicities and sexes. In fact, thirty percent of all post-menopausal women in the US and Europe will be diagnosed with Osteoporosis and at least 40 percent of those will suffer from a fracture in their lifetime.
Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your
Osteoporosis comes from the latin word meaning “porous bone”. If you were to look closely at a bone you could see there are these small spaces on the bone which is good, now if you look at someone who suffers from osteoporosis you will see these spaces are much larger. As these spaces become larger it takes away from the strength and integrity of the bone making it grow weak and thin. Osteoporosis is most common in women over the age of 50 and gives them a higher risk of fractures and or breaks especially common in the hips. While we know osteoporosis comes from a number of things it can be broken down to age, the hormonal changes most commonly seen in menopause and a lower intake of Vitamin D and Calcium. Age is the unpreventable factor that doctors or you cannot change. Hormonal changes can be fixed with supplements or hormone therapy along with ones intake of Vitamin D and Calcium. Hormone therapy, estrogen alone or the combination of estrogen and progestin have been proven to prevent and aide in the treatment of osteoporosis in
The skeletal system consists of 206 bones and has other body attachments that assist in connecting them which are tendons, ligaments, and cartilage. The skeletal system provides vital functions for the human body. The functions this system provides are support, movement, protection, blood cell production, storage for calcium and endocrine regulation. Bone serves as the basic unit of the human skeletal system. Ossification is characterized as a process that produces new bone. This process is also known as bone formation. Bone formation consists of two types of development. They are intramembranous and endochondral formation. Intramembranous ossification takes place when cells within the membrane change and become osteochondral progenitor cells.
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
The Skeletal System, also known as the Skeleton make up a framework that support the body and protect the organs. The Skeleton consists of the bones and joints of the body. In the human body there is 300 bones at birth, these then fuse together to make 206 bones in a fully grown adult. The Skeleton is made up of two divisions: The axial and appendicular Skeleton.
