Exercise Physiology Skeletal System

Blood cells are formed in...

• red marrow

• blood vessels

• osteon systems

• osteocytes

Which of these is NOT a function of the skeletal system?

• protect organs

• help transmit impulses

• provide levers for movement

• maintain body shape.

What is the name for the connector that attaches muscle to bone?

• ligament
• tendon
• patella
• string

What is the name for the connector that attaches bone to bone?

• ligament
• tendon
• patella
• string

What do the bones create?

• white blood cells

• platlets

• red blood cells

• protein

Why is a reduction in the viscosity of synovial fluid is an advantage (PICK TWO)

• Pain free movement and better technique

• makes the fluid thicker

• makes the joint stiffer

• Lubricates to reduce friction

Bone cells that live within the bone are called?

• osteocytes

• osteoblasts

• osteoclasts

• osteons

State TWO responses of the skeletal system in activity

• Increased synovial fluid

• synovial membrane opens

• reduced viscosity of synovial fluid

• lower joint temperature

What is the slippery surface that cover the end of bones and helps absorb shock?

• synovial membrane

• synovial fluid

• ligament

• cartilage

What is the function of synovial fluid?

• Acts as a lubricant that reduces friction in the joint; allows for smoother movement and reduces wear and tear.

• Surrounds and protects the joint, holding the bones together.

• Strong, elastic fibres that hold bones together and keeps them in place

• Strong but flexible material found at the end of the bones that acts as a cushion and reduces friction

• Produces synovial fluid which lubricates the joint.
