This paper explores the human skeletal system including its purpose, structure, and the common diseases and disorders that affect it. The human skeleton has a unique design meant to provide structural support and act as a reservoir for minerals in the body. The paper also expounds on the components of the skeletal system such as the axial and appendicular skeletal systems. The axial skeletal system is tasked with supporting the head, neck, and trunk. It is composed of the cranium, vertebral column, the rib cage, and the thoracic cage. The appendicular skeletal system, on the other hand, is composed of the limbs, upper and lower parts of the body like the femur, carpals, tarsals, and humerus. The body’s hardest parts are components of the skeletal …show more content…
system, and as outlined in the paper, movement of these rigid regions is aided by the presence of joints. Joints are essential parts of the skeletal system for they allow varying mobility designs at different locations and angles. The Skeletal System The Role of the Skeletal System Functions of the human skeleton are essential for survival for it gives the body its shape, strength and support. The frame prevents the buildup of pressure on the organs thus creating an environment where they can function properly (Kenney, 2016). Also, it protects delicate organs like the heart, lungs, kidneys, and liver in areas like the rib cage and skull from external shocks. Furthermore, bones act as leverage for movement since they are held together by ligaments and tendons which anchor the muscles to the bones of the skeleton. The larger bones of the skeleton are also involved in the production of blood cells in the red and yellow bone marrow. Organs in the Skeletal System The skeletal system is a connective tissue comprising of organs like bones, cartilage, tendons, and ligaments. Functioning of the Skeletal System Together with Other Body Systems The skeletal system functions with the central nervous system by surrounding its organs like the brain thus safeguarding the delicate nerve tissues from trauma.
It also functions with the muscular system in that contraction of the skeletal muscles requires that they are attached to something at each end so as to have support which in this case is a bone. Thirdly, the skeletal system functions with the hematological system during manufacture of new blood cells in the bone marrow (Pietschmann, 2016). Any defect in the skeletal system has a direct effect on the hematological system. Lastly, the skeletal system acts to maintain a balance of calcium in the body. It acts as a storage unit where excess calcium in the blood is stored and also from where the body can get extra calcium when its level falls in the blood.
Common Diseases and Disorders of the Skeletal System
Disorders of the skeletal system cause bone deformities and in the long run affect mobility. Among the disorders is arthritis which is the inflammation of movable joints and characterized by pain, swelling, and joint stiffness. The condition can also lead to the destruction of the capsule surrounding tissues and the bones (Tamparo, 2016). Another type of anomaly is osteoporosis which is a condition that occurs in older adults due to their bones becoming weak. It is as a result of lack of synthesis of sufficient bone tissue with calcium deficit being a precursor from primary cancer to the bones as in leukemia.
Facts about the Skeletal
System Observing the skeletal system, it is evident that the only bone lacking a joint is the hyoid bone in the throat. It is also a fact that the smallest bones in the body are found in the ear. Besides, adults tend to have 206 bones while infants have 300 which reduce as they grow (to the condition. Bone cancer is also a disorder of the skeletal system occurring as a result of metastasis Brett, 2015). Lastly, the female pelvis is more rounded, flatter and larger than a man’s pelvis. Effects of Social and Environment Factors on the Skeletal System Environmental factors that could be injurious to the skeletal system include doing heavy work like manually loading and offloading trucks. This strenuous activity could affect the bones by exerting too much stress on them thus weakening them. Social factors on the other hand like working out in a gym has an effect more so on the spine if the activity involves lifting heavy weights.
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
The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections
There are many different diseases that can affect our skeletal system and Osteoporosis is one of them. Osteoporosis lessens bone strength and bone density (amount of bone mineral in bone tissue), which will lead to fragile bones. It mainly affect the hips, ribs, spine, and wrists. Male or female, at any age, can get this but it is mostly occurs in older women (Team, 2016). Osteoporosis is very common, there are more than 3 million cases a year. There are many causes/risk factors, symptoms, and some treatment cases. About 54 million Americans have Osteoporosis and low bone mass (Foundation, 2016).
The skeletal system assists the muscular system to provide movement for the body. Certain muscles that are attached to bones contract and pull on the bones resulting in movement.
Osteoporosis is a condition, which advances with age, resulting in fragile, weak bones due to a decrease in bone mass. Externally osteoporotic bone is shaped like normal bone, however it’s internal appearance differs. Internally the bone becomes porous due to a loss in essential minerals, including phosphate and calcium. The minerals are loss more quickly than they can be replaced and in turn cause the bones to become less dense and weak. The bones become prone to fracture, due to their weakness. Therefore the awareness of the disease tends to occur after a fracture has been sustained. The bones most commonly affected are the ribs, wrist, pelvis and the vertebrae.
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 decrease of 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,
Like most systems in the body, the muscular system does work in isolation. The most obvious systems that interact the muscular system are the skeletal system, the nervous system and the circulatory system. Muscles are also involved in the digestive system, the respiratory system and the immune system. Let's discuss the relationship with the digestive system that the skeletal system has together. The skeletal system cannot produce it’s own calcium to strengthen itself. It depends on the digestive system. For example, when a person eats food that contains calcium and phosphorus, the body breaks the food down into smaller molecules that can be absorbed by the body bloodstream. Also with the aid of the circulatory system, the smaller molecules of calcium and phosphorus are then delivered into the bones tissues that need them for repair and to strengthen themselves. Bottom- line, the digestive system is a great help for the musculoskeletal system.
Osteoporosis is a serious disease that leads to a faster than normal loss of the bone density, which puts the bone at a higher risk for fractures. In order to understand the causes of Osteoporosis, it is important to understand how bones are formed. Bone is a living tissue that is made mainly of collagen, calcium phosphate, and calcium carbonate. The mixture of collagen and calcium gives the bone strength and flexibility. The body deposits new bones and removes old ones; moreover, there are two types of bone cells that control the reproduction of bones. Cells called osteoclasts breakdown bone tissues thus, damaging the bone. Once the damaged bone is removed, cells called osteoblasts, use minerals including calcium and phosphate from the blood stream to make new healthy bone tissues. In order for osteoblasts and osteoclasts to work properly, hormones such us thyroid, estrogen, testosterone, and growth hormones are
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
Other metabolic bone diseases are osteoporosis, gout, OSTEOARTHRITIS, and PAGET'S DISEASE. Nutritional Disorders Nutritional deficiencies that result in bone damage include RICKETS in children and osteomalacia in adults, caused by a lack of vitamin D. In children, calcium and phosphate are poorly distributed on bones during development, resulting especially in deformity of the legs and arms. In adults, bones of the spine, pelvis, and legs become demineralized and the bones weaken.
However some of the basic bone functions include storing of crucial nutrients, minerals and lipids, producing red blood cells for the body, protect the organs such as heart, ribs and the brain, aide in movement and also to act as a buffer for pH. With the differences in all of the bones there are four things that remain the same in each bone, their cells. Bones are made up of four different cells; osteoblasts, osteoclasts, osteocytes and bone lining cells. Osteoblasts produce and secrete matrix proteins and then transport the minerals into the matrix. Osteoclasts are responsible for the breaking down of tissue. The osteoblasts and osteoclasts are both responsible for remodeling and rebuilding of bones as we grow and age. The production of osteoclasts for resorption is initiated by the hormone, the parathyroid hormone. Osteocytes are the mature versions of osteoblasts because they are trapped in the bone matrix they produced. The osteocytes that are trapped continue making bone to help with strength and the health of the bone matrix. The bone lining cells are found in the inactive bone surfaces which are typically found in

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.
Support is a very important fuction as without the skeleton the body would have no means of staying upright as almost all of the body tissues are soft this helps gives the body structure. The Skeleton plays an important role in the protection of the organs for example the skull protects the brain and the ribcage protect the lungs.The skeleton assists in the movement of the body as the ligaments in the body attach bone to bone and the tendons attach muscle to bone. To create movement the muscular system and the skeletal system work together creating the musculoskeletal. The skeleton can begin to move once the muscles contract. The fifth function of the skeleton is the formation of joints, these are essential to create movement within the body. Muscle attachment allows the bones to move. This is done by the muscles attaching to the bones by tendons. Minerals such as calcium salts and phosphorus are stored in the bones. The final function of the skeletal system is the formation of blood cells; most of the blood cells for the body are produced by red bone
