Skeletal System Research Paper

1275 Words6 Pages

The skeletal system gives the body its basic framework, providing structure, protection, and movement. The 206 bones in the body also produce blood cells, store important minerals, and release hormones necessary to life. Aging is the process of growing old, especially by failure of replacement of cells in sufficient number to maintain full functional capacity. Aging greatly contributes to the degrading of our body structure and its functions.
As individual ages some cells do not replicate or divide to form new cells. We are born with just a finite amount of the cells which die gradually as we age. These cells are called G[ο] cells. The rate of the process of reproduction of other cells may also decrease. Aging cells function less well and …show more content…

The pupils react slower to changes in light intensity and the eyes produce less fluid causing them to become dry. The nerve cells also decrease number. These all contribute to the vision of the eyes getting bad. The sensitivity of the taste buds on the tongue decreases. The lining of the nose gets thinner and drier. The nerve endings in the nose deteriorate and the mouth begins to produce less saliva. These reduce the ability to taste and smell, which are linked. As you age, high pitched sounds become more difficult to hear and this is known as …show more content…

Older people become more prone to diseases such as pneumonia and influenza. Fewer blood cells are also produced due to a decrease in the amount of active bone marrow. The bone marrow is unable to increase blood production what the body is in need of it. The heart does not speed up as quickly and it along with blood vessels gets stiffer. Blood flow to the heart is slower, but, blood pressure increases due to less expansion of stiffer arteries when blood is pumped through them. Clots in the lumen of vessels tend to occur due to the gradual build up of fats which can lead to arteriosclerosis. Cholesterol level increases, which may contribute to coronary heart disease. The lungs absorb less oxygen due to a decrease in the number of alveoli. The chest along with present alveoli, become rigid. It loses some of its elasticity and the muscles which assist in breathing, such as the diaphragm,

    Cartoon Character Skeletal System Project Essay! The human skeletal system consists of 206 bones and associative tissue such as joints, cartilage, ligaments, and tendons. Each bone is a complex living organ that is made up of cells, minerals, and protein fibers. When joined together, the skeletal system provides the base framework, giving shape to the unique human body and provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachments points for muscles enabling movements at the joints.

    In Aging Backwards, author Miranda Esmonde-White describes how aging is more of a lifestyle choice than a length of time growing old. Esmonde-White’s main goal in writing this book is to expand knowledge to individuals that the reason why we age is because of neglecting certain areas on our bodies. Every muscle in our body is the key to living a long life. According to Esmonde-White (2014), “An organelle called mitochondria, is the powerhouses of cells.

    1.Telomerase Telomeres play a crucial role in cellular replication, with the loss of telomeres cell is unable to divide. Replicative senescence which is cell incapability to divide was first defined by Hayflick (Hayflick,2000). Hayflick observed that after a several number of cell divisions cells in culture ceased to propagate. 1.1 Telomerase maintenance Cells can attain immortality by two telomere maintenance mechanisms, the first pathway includes an action of ribonucleoprotein enzyme complex telomerase. Telomerase helps in the elongation of telomeres through nucleotide addition by catalyzing the de novo synthesis of TTAGGG repeats, thereby counteract shortening, of telomeres and allow indefinite cell proliferation.

    The bones do not work properly when not in good condition, and when they have aged, they start not working as properly. They can get worn down from overuse or when you have used your bones your whole life since your bones never change or re replaced. "Some are programmed to die naturally, but conditions like osteoarthritis and osteoporosis are linked with an increased level of cell death. In other words, when a higher number of osteocytes die, the bones become weaker" (World of Anatomy and Physiology). Aging can start at different ages for every person, but for most women it starts in their thirties and for men it usually starts in their fifties.

    Telomeres and ageing Ageing is a natural process and it is relevant in both scientific and social aspects of life; understanding why and how ageing occurs is vital to gaining a greater insight into how organisms work. Looking at telomeres is one of the main ways to learn about ageing. What are telomeres? DNA is arranged into chromosomes which are found in the nucleus of all eukaryotic cells. The genes that are found on chromosomes code for proteins that are essential for organisms to survive, for example enzymes needed for metabolic processes such as respiration.

    The wear and tear theory of aging believes that through time, the body begins to fall apart due to wear and tear caused by damage done to cells and body systems. It suggests that if people do not take care of their health through the aging process there may be some conflict or problems that may affect a person’s ability to cope in old age. For example, when you purchase a new vehicle, basic car maintenance is recommended to ensure that you do not experience or encounter any form of car trouble or failures. In consideration to the wear and tear theory of aging, in order to prevent a conflict to adult development that may affect a person’s ability

    Although the term "aging  might conjure up only a few wrinkles in one's mental imagery, there is much more to aging than the physical aspects. There are four different types of aging discussed in the text: chronological, biological, psychological, and social aging. There is a necessary distinction between these categories of aging. They are unique in the description (i.e. 70 years of age, wrinkled skin, Alzheimer's disease, a senior citizen, etc.), but related because these descriptions determine the "age  of an individual. Chronological age describes the years that have passed since the individual was born.

    Effects of Aging on the Human Body Aging is an intrinsic part of life and as of now there is no way to bypass it. There are many theories as to what specifically causes aging, most notably damage based theories, such as Orgel’s Hypothesis, energy metabolism, free radical theory of aging, and DNA damage theory which includes the theory of the unraveling of telomeres. There are ways to prevent the negative effects that may accompany aging through lifestyle choices such as diet and exercise. Sadly, many diseases or syndromes that present themselves later on in life are linked to heredity or wear and tear of the body. Aging effects the entire body and there are many diseases and problems that arise from it.
