Transcript of Musculoskeletal System
The changes that occur as we age
From about age 30, the density of bones begins to diminish
Bones become more fragile and are more likely to break
The cartilage inside a joint becomes thinner
Joints become stiffer because the connective tissue within ligaments and tendons becomes more rigid and brittle
What we can do to help slow this aging changes
Exercise can make bones stronger and help slow the rate of bone loss.
Balance and coordination exercises, such as tai chi, can help reduce the risk of falls.
Stretching is another excellent way to help maintain joint flexibility.
Weight-bearing exercise, such as walking or weight training
Exercise in water may still experience increases in bone
Helps to support the weight of the body
The bones work together with muscles to maintain body position and produce controlled, precise movements.
The skeleton pulls against, contracting muscle fibers that allow us to sit, stand, walk, or run.
What Makes up the Musculoskeletal System?
The skeletal system includes the bones of the skeleton and
Other connective tissue that stabilize or connect the bones
Effects of normal aging changes
Loss of muscle that starts around age 30 and progresses throughout life
The amount of muscle tissue and the number and size of muscle fibers gradually decrease
The result is a gradual loss of muscle mass and muscle strength
This mild loss of muscle strength places increased stress on certain joints and may lead a person to arthritis or falling
What we might see with our patients in our care experiencing with these changes
Reduced tolerance to exercise
Muscle fibres reduce in number and shrink in size.
Interaction with other body systems
Protects internal organs and produces blood cells.
Bones provide calcium that is essential for the proper functioning of the nervous system.
The skull protects the brain from injury.
The vertebrae protect the spinal cord from injury.
Ribs protect heart and lungs
The brain regulates the position of bones by controlling muscles.

Keeping the Musculostal System healthy
Don't overextend your joints
Eat smart; such as calcium-rich foods and foods with vitamin D
Be fit; 30 minutes of weight-bearing exercise at least twice a week
Avoid smoking and drinking
