Btec sport - Skeletal system Exam Questions
And Answers 100% Pass
What is an osteoblast? - answer✔- growth & repair = bone remodelling
- Bring calcium to the bone
- osteoblast activity inc when exercising (heavy resistance)
= bones will become more dense + stronger
- reduces osteoporosis
What is an osteoclast? - answer✔- unnecessary Ca+ is removed from certain parts of bone
- dissolve bone
= while new layers of bone tissue are created
- come from bone marrow
Long bone - answer✔- Enables large ROM such as a bowl swing in cricket using the humerus long bone
- Found in limbs + muscular attachment
- e.g. femur & phalanges
Short bone - answer✔- Shock absorption
- weight bearing +
- Small, light & strong at joints
- e.g. tarsals when running
(Wide + short = short bone) (wide + long = long bone)
Flat bone - answer✔- E.g Sternum
- larger SA = Attachment for muscles
- protection (e.g. vital organs)
- Thinner

Irregular bones - answer✔- Complex shape E.g vertebrae protects Spinal Column
- provides mechanical support
- support of muscle attachment e.g. erector spinae attaching to sacrum
- other e.g. = patella
Sesamoid bones - answer✔- Usually found in a tendon or muscle = protection
- provide smooth surface for tendons to slide over
= inc movement at joint
- E.g Patella + phalanges
List the type of joints used at the elbow and wrist + articulating bones + movement produced -
answer✔- Elbow -> Hinge -> Humerus + Radius + ulna -> flexion + extension
- Wrist -> Gliding -> Humerus, radius, carpals (ulna not a part of wrist) -> flexion, extension, adduction,
abduction
Anterior - answer✔To the front
Posterior - answer✔To the behind
Medial - answer✔Towards the midline
Lateral - answer✔Away from the midline
Proximal - answer✔Near to root (origin) of body e.g Proximal of the arm is the shoulder
Distal - answer✔Away from the root E.g Hand
Superior - answer✔Above
Inferior - answer✔Below
Axial Skeleton - answer✔Skull, Thoracic cage, Vertebrae
What are the names, how many discs each of them have, and order of how the vertebrae run? -
answer✔- Cervical (7)
- Thoracic (12)
- Lumbar (5)
- Sacrum (5)
- Coccyx (4)
