The vertebral column forms a stable but mobile axis for the rest of the body. It is made up of • Bones • Joints • Discs • Ligaments • Muscles • Tendons • Blood vessels The bones provide strength and are honeycombed for lightness, and ligaments , tendons and muscles provide stability. The muscles are also a source of power and provide movement and support for the spinal column, maintaining the natural curves and controlling excessive bending. Muscles are the first line in defense in protecting other structures of the back. Joints are where two or more bones meet.
THE SKELETAL SYSTEM – BONES AND JOINTS The skeleton consists of axial and appendicular components. The axial skeleton consists of the skull, vertebral column and bones of the thorax, while the appendicular skeleton consists of the pectoral girdle, pelvic girdle, and bones of the upper and lower limbs. You do not have to remember the names of all the bones of the body but you should familiarise yourself with those indicated on the diagrams below. There are different categories of bones: long bones, short bones, flat bones, sesamoid bones and irregular bones. Long bones – The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones.
The skeletal system The skeletal system is the system in our body that supplies protection to the vital organs and support for the muscles and skin. The skeletal system is the utmost important system in the body; it holds the systems together assist anting the weight of the body. This support is provided by bones, structures as strong as reinforced concrete but considerably lighter. Oppose from concrete, bones can be remodeled and reshaped to meet changing metabolic demands and patterns of activity. Bones operates with muscles to conserve body position and to construct controlled, defined movements.
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
The skeletal system provides us with many important functions, it provides us the shape and form for our bodies as well supporting, protecting, allowing our body to move freely, producing blood for the, and storing minerals. The skeletal system is the system of our body that gives our body its physical shape and with the help of the muscular system it keeps us moving and makes us able to do task that we dont think about like raising our leg to kick a football. The average adult skeleton has 206 bones that joined up with ligaments and tendons to make a protective and supportive framework muscles and the soft tissues which lie underneath it. The skeletal system has two main parts- the axial skeleton and the appendicuar skeleton. The axial skeleton contains the skull, spine, ribs, and the sternum and includes another 80 bones.
KEYWORDS: Skeletal system, Arthritis, muscles, activities of daily living. The skeletal system is one of the most unique organ systems in the human body as it compliments other organ system such as the muscles. The skeletal system consists of various sizes and shapes that add characteristics for support and mobility of the body. Our bones provide protection to our vital organs such as the heart and the brain. The skeletal system is the main foundation of the human body, without this, we cannot function as human beings.
The typical structure of a long bone consists of epiphyses, diaphysis, epiphyseal line, periosteum, endosteum and articular cartilage. Bones are formed through ossification which includes intramembranous and endochondral occification. The skeleton is divided into two parts: the axial and the appendicular limb, the pelvic girdle and the lower limb. Bone calcification is the process by which calcium is deposited into the bone
[2] The skeletal portion of the system serves as the main storage system forcalcium and phosphorus and contains critical components of the hematopoietic system. [3] This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide the stability to a body in analogy to iron rods in concrete construction. Muscles keep bones in place and also play a role in movement of the bones. To allow motion, different bones are connected by joints.
The skeleton system has two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the spine, the ribs and the sternum (breastbone) and includes 80 bones. The appendicular skeleton, consisting of 126 bones, includes two limb girdles (the shoulders and pelvis) and their attached limb bones. Bones have two main purposes which are for you to stand correct instead of lying down on the floor like puddle of skin/mud. Other bones protects the delicate and sometimes the soft parts of your body.
The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Your cranium skull protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae spine, backbones protect your spinal cord. Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons are tough inelastic bands that hold attach muscle to bone. There are many differences between the male and female human skeletons.
