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 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.
What is the function of the ligaments?
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. Acts as a stabiliser.
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.
How does a synovial joint respond to exercise (pick 3 that apply)
Synovial fluid leaves the joint
Synovial fluid viscosity is reduced for better mobility
Blood flow is increased to deliver nutrients
the joint becomes stiffer
friction is reduced for pain free movement
Which sports have high bone mineral density (click 2 that apply)
swimming
rugby
weight lifting
cycling
rowing
What do osteocytes do (pick all that apply)
maintain bone strength
cools the bone down
trapped in bone matrix ready to disperse minerals
direct osteoclast to areas needed for rebuilding
carries iron and nitrogen
Osteoclasts will work faster when ________ is detected in the blood stream
Calcium
Vitamin D
Creatine
Phosphate
Weight bearing exercise will increase the activity of which bone cells
Osteoclasts
Osteocytes
Osteoblasts
Osteoids
