The musculoskeletal system The musculoskeletal systems functions are to support the body's shape, to protect important organs, to help the body's movement, to produce blood cells and to store Calcium and phosphorus. The musculoskeletal system is made up of bones, cartilage, tendons and ligaments. There are around 213 bone sin the human body and they are all linked through tendons and ligaments. These form the protective and supportive framework for muscles. Men's bones are usually larger and heavier than the bones that are in women. Also women's pelvises are wider than the ones that are in men's, this is so women can have and support their babies more. There are 3 types of joints that connect bones; these are fixed joints, mobile joints and ball and socket joints. Fixed joints are the joints that are between the bones in the skull. Mobile joints are like hinge joints of the elbow or pivotal joint like the joint between the first and second vertebrae. This allows the head to turn from side to side. Ball and socket joints allow the widest range of movement like the shoulder and hip joints. ...read more.


Smooth muscle fibres are usually involuntary which means they aren't under conscious control and they are smooth. Certain smooth muscle fibres like the ones in the uterus, keep their shape and size. � skeletal muscles (striped or voluntary muscles) - Skeletal muscles areattached to bones and it is striated. Skeletal muscle tissue can be made to contract or relax by conscious control so this means it is voluntary. The skeletal muscles are around 40-45% of a persons total body weight. They are called skeletal because they are attached to the bones of the skeleton and are also called voluntary muscles because a persons body can control their movement and actions. Each muscle is can contract and relax to make the body move. There are around 600 muscles in a human body and each are organized into categorise to what action they perform, these are; � extensors - these open a joint and flexors close a joint. � Adductors - these draw part of the body inwards � abductors - move the body outwards � levators raise a part of the body depressors lower part of it. ...read more.


A fractured bone in an older person can be serious depending on where it happens in the body. It may lead to long-term disability, an example of this would be a hip fracture may lead to long-term problems with mobility. Bones are at their strongest in adult life and are constantly repaired through a process called bone turnover. As the body ages, this process is no longer balanced and bone loss happens a lot more. This means that bone is very slowly broken down over time, leading to a decrease in bone density as the body gets older. This can cause the bone to become weaker and increase the risk of breaking a bone. The Department of Health (DH) published a National service framework (NSF) for old people. This givesdoctors, nurses and all healthcare staff guidance on how to provide care to patients. It sets basic standards for the care of older people, including: � stopping age discrimination � giving person-centred care � increasing older people's health and independence � fitting services around people's needs The NSF also says that every area in England should have integrated services aimed at preventing falls and fractures. ?? ?? ?? ??
