Skeletal Flashcards
What is used in bone remodelling
-osteoblasts
-osteoclasts
What is a defect u can have of the spine
Scoliosis
2 bones in the leg
-femur
-tibia
-fibula
-patella
2 arm bones
-humerus
-radius
-ulna
What do osteoblasts do
Form bone
What do osteoclasts do
Remove bone
3 functions of the skeleton
-movement
-leverage
-protection
What is the function of red blood cells
Carry oxygen to muscles
Give me all bone types
-flat
-long
-short
-irregular
Give me the 2 main joints
-hinge
-ball and socket
What is the function of the synovial fluid
Lubricates the joint to reduce friction
Function of the ligament
Connects bone to bone
Function of the bursa
Acts like a cushion and reduces friction
Function of articular cartilage
Reduce friction and absorb shock
Describe flexion and extension
Reducing or increasing the angle at a joint
Describe planter and Dorsi flexion
Only occurs at the ankle where toes pint to the sky or downwards
Describe abduction and adduction
Abduction-moving away from the midline of the body
Adduction-moving towards the midline of the body
Describe circumduction
Like rotation but not full 360 degrees example=butterfly stroke
3 short term responses to exercise
-increase mineral uptake
-increase pliability of ligaments
-bone remodelling
3 long term responses to exercise
-increase ligament strength
-increase bone density and strength
-increased thickness of cartilage
Explain what happens when you have arthritis
Your cartilage will thin so much that your bones will rub causing pain typically seen in older people
