Functions Of The Skeleton The human skeleton has 6 main functions that provide the body with good health. They are as follows: Support - our skeleton provides shape and support to our body which gives our body its shape, without this function our body would simply collapse. Movement - it aids our body to move by giving a framework to the attached muscles which then allows different movements at different joints. Movement is therefore powered by the skeletal muscles. Protection - the skeleton provides protection to many important organs. The skull protects the brain, eyes and ears. The vertebrae protects the spinal cord from any damage. The rib cage prevents any damage to the lungs, hearts and major blood vessels. The illium are there to protect the digestive system. Blood cell production – the skeleton is the place of haematopoiesis which is produced in the red bone marrow. Storage – bone tissues stores various minerals such as calcium and phosphorus, they release these minerals into the body when required. Leverage - this is the function which gives the body movement by making the bones act as levers. These levers are responsible for changing the direction of force created by the muscles in our body. Endocrine regulation¬¬¬¬¬¬ – the cells in the bones release a hormone known as osteocalcin which helps regulate glucose levels and fat deposition. On top of spiking up the production of insulin and reducing stores of fat it also increases the secretion of insulin. Skeletal System The skeletal system consists of 206 bones and is made up of the axial and appendicular skeletons. The axial skeleton is the central line of the body which consists of the cranium, vertebral column and rib cage. It is for... ... middle of paper ... ...em releases energy without the need of oxygen. It is broken down very quick and utilized to turn ADP into ATP. This energy system is very useful for quick and short bursts activities of 10 seconds such as the long jump and javelin. Creatine phosphate is limited in muscles for that reason most athletes use supplements to increase their creatine phosphate in the body. Lactic acid energy system also gives out energy without the need of oxygen. Energe is developd from the break down of glucose from glycogen and blood sugar. However the glycogen isn’t fully broken down and the process is known as anaerobic glycolysis, which leaves something known as latic acid. As lactic acid gather in the muscles, the muscles get weaker and fatigued. This energy system is use-able for about 2 minutes which makes it suitable for events such as the 100m swimming and the 400-800m run.
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
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 remarkable strength of the bones in this system provides protection for the vulnerable organs in the body.
The Skeletal system performs vital functions; supports movement, protection, blood cell production, calcium storage and endocrine regulation. That enables the human body to survive.
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).
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
When a person exercises the body uses either sugar or fatty acids as fuel to create energy. During the beginning of an exercise most of the sugar that is used as fuel comes from the bloodstream or the muscles. After about 15 minutes the fuel starts to come from the liver. When one exercises after 30 minutes the body receives energy from free fatty acids and glycogen gets stored resulting in a decrease in blood sugar levels. Glycogen is the sugar stored in the liver and muscles.
Bone Homeostasis is the bones regulation spefic process Inorder to allow the body to function properly.
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
Most people have misconception about if the bone is a living structure. Inside the bone there is a living tissue which is the cortical bone and trabecular bone. Bone cells that responsible for bone production included osteoblasts, osteocytes and osteoclasts. Meanwhile, bone can heal itself when a bone fracture happen.
The skeletal system is actually broke into two sections, One section being the axial skeleton. This is made up of the 80 bone of the skull, spine, ribs and sternum or breastbone. The other section being the appendicular skeleton. This is made up of the 126 bones of the shoulder, arms, hands,
There are three different types of muscles in the body, and the first to be talked about are skeletal muscles. The body consists of about 640 skeletal muscles and they just so happen to be the only voluntary or (controlled) muscles. Their main function is to contract and expand so that your bones are able to move. Most skeletal muscles are attached to bones or joints so that the muscle can either expand or contract to create motion. They consist of band like fibers attached and bundled together that run along the bone. These fibers are held together by connective tissue called epimysium, which also protects the muscle. Skeletal muscle is what makes the body able to walk and move, without these skeletal muscles the body could not function properly because it would have nothing to rely on for stabilization and strength. They contain what is called striated cells, which is cells that are shaped like bands and are individual, they stretch out the length of the muscle so that they are able to contract with it and these cells are also what give the muscle energy through respiration of proteins fats and glucose which is the energy supplement for all muscles. For example refer to figure 1-1 1-4 and1-5 for the cell
The cranium provides maximum protection with minimum weight, the ideal combination. The other twenty bones make up the face, jaw and other parts of the skull. Another way the brain keeps it self safe is by keeping itself in liquid. Nearly one fifth of the blood pumped by the heart is sent to the brain. The brain then sends the blood through an intricate network of blood vessels to where the blood is needed. Specialized blood vessels called choroid plexuses produce a protective cerebrospinal fluid.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
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
