The skeletal provides functions such as support, protection, and movement. The skeletal system provides a framework that supports the body with muscles attached to them acting as levers allowing for movement. As bones are very rigid they provide support for vital organs such as the heart, lungs and brain. A physiological function of the skeletal system is the production of stem cells through red bone marrow found in the proximal epiphysis (the ends) which can become lymphocytes (white blood cells), erythrocytes (red blood cells) and thrombocytes (platelets).
Cartilage serves as protection against bone on bone contact to prevent wear in bones an example of this is the lateral and medial meniscal cartilage (articular cartilage). But the lateral and medial meniscal cartilage can be quite easily torn although a common injury in fully grown adults torn cartilage cannot be healed as cartilage receives little blood flow making it hard for it to heal compared to children with

Thus, the recommended treatment for a patient with osteoporosis would receive supplementary calcium (1,000 to 1,500 mg of calcium daily) as confirmed in the National Institutes of Health Consensus Development Conference on osteoporosis in 1984. But studies have shown that as humans age their ability to absorb calcium starts to diminish making this treatment almost ineffective in some elderly patients. Patients of this time, with little treatment options were forced to endure many fracture related injuries; most commonly fractures of the hip which is a very complicated fracture requiring hospitalisation and a surgical practice would be required. Even if the surgery had been successful the patient would not be able to return to the previous levels of activity they were once at; forcing the patient from self-care to supervised living situations/nursing
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 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.
Now, when considering one wants to prevent or treat Osteoporosis, it does not mean to cut yourself off of foods with small portions or extreme dieting. It is a common misconception that when a person wants to be healthy they must eat in smaller portions, and while this does have some truth, one must consider when it comes to eating healthy, it means to eat healthy by adding nutritious portions of fruits, vegetables, protein, carbs, and of course, calcium intake for the bones in one’s diet. Also, one must not deprive themselves of having a “cheat day” once a week with chips and candy. But it is a good start to begin adding calcium fortified foods and supplements, such as milk. People should at least aim for 1,000 to 1,200 milligrams a day of calcium. Low-fat cheese, milk, yogurt, orange juice, graham crackers, and calcium supplements are a beneficial contribution in accessing calcium to the body (Vander, 2003). Of course, Osteoporosis develops during old age, due to the gradual decline in exercising, calcium in bones, and weight loss. However, Osteoporosis is also genetically found in some people with a long history of family members who have had bone fractures. Also, many factors affect and can cause Osteoporosis and one of them is smoking. Because smokers have poor lungs, it can be difficult to exercise. Another is not going out too much,
Two groups of Lister strain of black and white hooded Norwegian rats were used. Young rats, six to eighteen month old, were used due to their rapid and vigorous cellular response. They each had incisions made through the pericranium, skull and dura mater to study bone repair with reduced blood supply to the fracture site. The fracture was created in the cranial vault as cartilage is rare in this site and there minimal mechanical factors are involved. By examining the rats at different intervals during the repair phase Girigs & Pritchard (1958) were able to support the study of Pritchard (1948) that in a healing fracture cartilage is produced due to reduced blood supply. They found that since cartilage is less demanding of oxygen it acts as a temporary bridge between the fracture gap until blood supply is restored Thiymidine was used on forty two, five week old female rats to conduct an autradiographic study the cellular response in fracture repair. Observations of the periosteal index were conducted at several intervals between the period of one hour and fourteen days. The results show cellular proliferation in the periosteum and the adjacent soft tissue as being the initial...
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.
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.
In order to understand how the menisci can be injured, you must understand the basic anatomy of the menisci and why they are important. The menisci are two oval (semilunar) fibrocartilages that deepen the articular facets of the tibia and cushion any stresses placed on the knee joint. They enhance the total stability of the knee, assist in the control of normal knee motion, and provide shock absorption against compression forces between the tibia and the femur (Booher, 2000). Articular cartilage covers the ends of the bones that make up the joint. The articular cartilage surface is a tough, very slick material that allows the surfaces to slide against one another without damage to either surface. This ability of the meniscus to spread out the force on the joint surfaces as we walk is important because it protects the articular cartilage from excessive forces occurring in any one area on the joint surface, leading to degeneration over time (Sutton, 1999).
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 is made of all the bones, connective tissues and joints in the body. Bones, cartilage are some of the bones that make up the Skeletal system. The Skeletal system helps perform important everyday functions, for example; support, movement and protection, etc. The skeletal system helps form blood cells. The skeletal system helps store calcium and phosphorus, which is important and beneficial to the other functions in the body.

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.
Homeostasis is responsible for keeping biological conditions intact, such as our PH levels and blood pressure. As stated in Chapter 1.1 Overview of Anatomy and Physiology, it is “the state of steady internal conditions maintained by living things.” It also serves as the process that maintains and regulates our natural functioning, in other words. The importance of homeostasis in the body is to make sure that each internal role is functioning correctly. Throughout this paper, we will discuss how homeostasis affects the skeletal system. To understand homeostasis and its effects on the skeletal system, we must first learn the skeletal system itself. The skeletal system is made up of bones and cartilage and functions to support the body, produce blood cells, and store and release minerals and fat.
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
