1
Q

What are the 5 functions of the skeletal system ?

A
  • protection of vital organs - keeps organs safe
  • muscle attachment - they need strong points to attach bones providing framework
  • joints for movement - allow the body to move , small movement or large movement
  • storing calcium and phosphorus - 2 vital minerals for healthy bones
  • red and white blood cell production - when oxygen content drops/red blood cells they produce more.

Q

What is a flat bone ?

A

Flat bones usually protect organs or offer a good surface for muscles to attach to. For example, the ribs protect the heart and lungs, while the broad scapula has three muscles attached to it. Other flat bones are; scapula, cranium and clavicle.

17
Q

What is an irregular bone ?

A

Irregular bones have odd shapes and vary in function. An example is the vertebrae which help protects the spinal column and the sacrum which has lots of attachment points.

18
Q

Why is long bones important in sport ?

A

These bones are vital to generate movement, strength and speed. They usually act as levers. When they are pulled by different muscles, they enable the body to move.

19
Q

Why are short bones important in sport ?

A

Short bones are usually associated with weight baring, shock absorption and spreading loads. They play a key role in activities like jogging, playing tennis or dancing

20
Q

Why are flat bones important in sport ?

A

Flat bones protect your organs in contact sports and provide attachment for muscles to help movement.

21
Q

Why are irregualr bones important in sport ?

A

Irregular bones offer protection when playing sport, they tend to form specific functions for example the first and second vertebrae allow the head to turn and nod.

22
Q

What are the 4 types of joints

A
  • condyloid
  • pivot
  • ball-and-socket
  • hinge
23
Q

What is a pivot joint ?

A

Pivot joints allow bones to rotate . In a pivot joint , one bone shaped like a cylnder rotates inside another bone or ligament that makes a ring around it . E.g the atlis and axis in our upper neck

24
Q

What is a ball-and-socket joint ?

A

In a ball and socket joint its the rounded head of your femur or humerous for example entering your hip which acts as a socket being the pelvis or scapula which allows alot of ranges in motion

25
Q

What is a hinge joint ?

A

A hinge joint is a joint that allows forward and backward motion - just like the hinge on a door . There are three hinge joints : knee ankle and elbow .

26
Q

What is a condyloid joint ?

A

A condyloid joint is similar to a ball and socket joint but the ball rests against the end of a bone , rather than inside a socket . This allows a circular motion

27
Q

What type of movement is flextion ? Where is it found ? Give a sporting example .

A
  • bending movement that decreases the angle between body parts
  • Shoulder, hip, elbow
  • Someone working out in the gym bends their arm up when doing a bicep curl
28
Q

What type of movement is extension ? Where is it found ? Give a sporting example .

A
  • straightening movement that increases the angle between body parts
  • shoulder , hip
  • Aswimmer swings the arm backwards in preparation for a racing dive
29
Q

What type of movement is Dorsi-flexion ? Where is it found ? Give a sporting example .

A
  • bending or flexing the toes up, closer to the shin
  • Ankle
  • Asprinter positions their feet in the starting blocks
30
Q

What type of movement is plantar flexion ? Where is it ? Give a sporting example .

A
  • extending or pointing the toes down, away from the shin
  • Ankle
  • A floor gymnast points their toes
31
Q

What type of movement is adduction ? Where is it ? Give a sporting example .

A
  • movement that pulls towards the midline of the body
  • Shoulder, hip
  • A golfer on the tee swings the club down towards the ball
32
Q

What type of movement is abduction ? Where is it ? Give a sporting example .

A
  • movement that pulls away from the midline of the body
  • Shoulder, hip
  • A gymnast moves their arms out sideways at the shoulder when performing ‘the crucifixno the rings
33
Q

What type of movement is circumduction ? Where is it found ? Give a sporting example .

A
  • moving in a circular or conical shape
  • Shoulder, hip
  • A cricketer bowls a ball
34
Q

What type of movement is rotation ? Where is it ? Give a sporting example .

  • Shoulder, hip
  • A tennis player serves
35
Q

What is a tendon ? Why are they important in sport ?

A

Tendons are non elastic fibres that attach muscle to bone and allows them to move . Tendons grow in strength the more you use them
