Skeletal Muscle
The Aging Musculoskeletal System
The human musculoskeletal system is the organ system that gives humans the ability to physically move, by using the muscles and skeletal system. It consists of the muscular system and the human skeleton. Bones are connected to each other at the joints by ligaments or cartilage and skeletal muscle is attached to bones, usually by tendons. Bones mass or density is lost as people age, especially in women after menopause. The bone loses calcium and other minerals. Bone is a constantly changing tissue that has several functions. Bones serve as rigid structures to the body and as shields to protect delicate internal organs. They provide housing for the bone marrow, where the blood cells are formed. Bones also maintain the body 's reservoir of calcium. Bones come together to form joints. The configuration of a joint determines the degree and direction of possible motion.
Osteoporosis is a disease that is defined by low bone mass and loss of bone tissue basically thinning of the bones that lead to weak and fragile bones. (Aging in the bones-muscle-joints 2012). Bones are in a state of changing where new bone tissues are replacing the old bone tissue in order to keep the strength. It affects men and women, but it is usually a disease that affects women. However, when someone is diagnosed with osteoporosis it means that the bone tissue and mass is not replaced as fast with new bone tissue, which is one factor of osteoporosis. Another factor that causes osteoporosis is a deficiency in estrogen which typically occurs in menopause, causing low bone density because of the drop of estrogen. The probable effects of osteoporosis on an everyday life of an 84- year old thin white female may be critical. Since the bones become so thin and have low bone density, a minor fall can cause a fracture.
Of all bone deficiencies osteoarthritis is the most common. It typically comes with aging and wearing of the joints. According to Hugle et al. (2012) half

    ANSWER: Bone brittleness results from a decrease in the rate of protein synthesis and in the production of human growth hormone, which diminishes the production of the collagen fibers that give bone its strength and flexibility. As a result, inorganic minerals gradually constitute a greater proportion of the bone extracellular matrix. Loss of bone mass results from demineralization and usually begins after age 30 in females, accelerates greatly around age 45 as levels of estrogens decrease, and continues until as much as 30% of the calcium in bones is lost by age 70…

    Throughout the Human Body Systems course, you will explore the many functions of the skeletal system. Bones, cartilage, ligaments and tendons are all types of connective tissue that support your frame. The human skeleton is a wonder of design and engineering. It is incredibly strong and affords us great protection, but it is also incredibly light, giving us a great range of mobility. As you go on to explore the human body, knowledge of bone names will help you navigate the world of muscles and joints as well as other body systems.…

    Great job once again on answering the question about how muscle action relates to the movement. I think maybe I took it to the extreme, I went on about agonist, synergist, and antagonist muscles. I wasn 't sure if I should add the levers too. It appears as though you explained every type of muscle movement and gave an example of each. I went into flexion at the elbow and discussed that the agonist is the main muscle mover, the antagonist does the opposite, and the synergist is the helper. However, if you think about it, we kind of still came up with the same answer. You discussed flexion and extension and how they are opposites. That is what I wrote except I said that the agonist, or the main muscle, is used for flexion, while the antagonist is used for extension. You noted that these were opposites and so did I.…

    Muscular Atrophy is a decrease in the mass of a muscle. This leads to muscle weakness. An 84-year old thin white female with this disease will be in constant discomfort and is already lacking in muscle because of her age and size and will become weak due to the decrease of muscle mass. She will be unable to perform certain tasks or worsen the risks of accidents while performing normal daily activities such as walking. This disease is common among the elderly. (Wikipedia, 2013)…

    The skeletal system can suffer from a few diseases one of the most common ones is Osteoporosis another one is Osteogenesis imperfecta. Osteoporosis affects in a progressive way that deteriorates bone mass. Making the bones weaker lacking density and causing to have the deficiency on the bones protein intake this can bring about to the one who has it more vulnerable to skeletal fractures. Osteogenesis imperfecta disturbs the connective tissue or the ability of building it making the bones brittle in way more defenseless to wounds. Both this conditions are critical and need to be treated on the notion of knowing one suffers from them.…

    The human body is amazing in so many different ways, but yet very complex. So many things are happening all at once. The human body is sustained by the skeleton which is composed of the three most important parts: bones, cartilage, and ligaments. The Skeletal System is composed of two-hundred and six bones. Each of the bones are connected to another bone by ligaments and or tendons. Ligaments are a strong, flexible, and fibrous tissue that connects two bones or cartilages or holds together a…

    The human skeleton provides support and structure to the body. As a child we are born with about 300 bones. Once we become adults, the body has 206 bones. The reason why we are born with more bones is because as we age, some bones combine together to form a solid structure. Also as we mature, the postures in our bodies change, bone density can start to vanish, and the spine vertebrae’s can compress which triggers the trunk to appear shorter. Muscles also change as we age. There are more than 600 muscles in the human body. Muscles vary from smooth to cardiac to skeletal muscles. They do everything from pump blood into the body to control movement in certain parts of the body. As we grow older, muscles may lose their density, flexibility and tone.…

    Osteoporosis is a bone disease that can get worse with time. Your bones become fragile due to losing bone mineral density and bone mass. People do not realize this disease is occurring because they cannot feel their bones becoming weaker ("What is osteoporosis," 2011). Osteoporosis is most likely caused by three imbalances in the human body. Cause number one is a low magnesium/high calcium ratio. Cause number two is your female/male hormone is low. Cause number three is a low thyroid function ("The causes of osteoporosis,").…

    Bone is constantly remodeled in response to microtrauma. This remodeling occurs discretely in the skeleton and bone resorption is always followed by bone formation, a phenomenon called coupling. Architecturally, cortical bone differs from spongy trabecular bone, but their molecular compositions are similar. They both have an extracellular matrix with mineralized and nonmineralized components. Mechanical properties of a bone are mainly directed by the constitution and architecture of the extracellular matrix. Collagen and minerals play a great role on bone strength (Rossouw et al, 2002).…
