Q

Spongy Bone

A

-Found inside & at the ends of bones

-Red blood cells are produced within red bone marrow located in the cavities between the trabeculae
-Red bone marrow forms the structural foundation of spongy bone
-20% of skeletal mass
-Predominant type of bone tissue in the axial skeleton

Q

Why do women have more bone related issues?

Q

Aging Joints: Water

A

-Total body water decreases
-Pulls water out of the cartilage pads found between vertebrae (vertebral discs)
-Decreases flexibility & eventually stiffens the spine

Q

Aging Joints: Collagen

A

-Structural component of cartilage, tendons, & ligaments
-Produce less collagen so articular cartilage begins to thin & wear away
-Joints lose cushioning & lubrication and become stiff & achy
-Ligaments & tendons become stiffer & more brittle decreasing flexibility & movement

Q

Aging Joints: Blood Supply

A

-Capillary supply to the synovial membrane drops resulting in less synovial fluid produced
-Causes joint stiffness and immobility
-Allows debris & microbes to accumulate in the synovial cavity, further impairing mobility
-Though collagen production begins to slow around age 25, age-related changes in the joints usually aren’t apparent until age 40

25
What is the rheumatoid arthritis major mechanism?
Synovial Membrane
26
When do symptoms of rheumatoid arthritis usually appear?
Between the ages 30 & 40
27
Rheumatoid Arthritis Active & Inactive Phase
-Active Phase: relapse resulting in inflammation, pain, limited ROM, & fatigue -Inactive Phase: remission
28
Rheumatoid Arthritis Traits
-Bilateral in nature -Generalized fatigue -Auto-immune disease -No cure
29
Age Related Injuries & Conditions: Sprains
-Active seniors & tend to sprain wrists & ankles more frequently than younger people -Due to impaired balance, diminished muscle mass, weakened joints & shorter/tighter ligaments -Ligaments are overstretched resulting in swelling, pain, & reduced range of motion -Once a joint is sprained it is more susceptible to future injury -Most sprains respond well to RICE though more serious sprains require medical attention
30
Exercise Precautions of Skeletal Disorders
-Be aware of comorbidities -Avoid heavy weight-lifting -Avoid high-impact activities -Avoid explosive or twisting machines -Balancing issues (avoid free weights)
31
How often is recommended for someone to stretch with skeletal disorders?
5-7 days per week
