Flashcards in The Skeletal System Deck (34):
1

The skeleton has 5 main functions what are they

Support/Shape,Protection,Movement,Making Blood cells/platelets and mineral storage

2

The skeleton has what type of frame

Has a rigid bone frame

3

What does the skeleton support

The skeleton supports soft tissue like skin and muscle

4

Bones are very tough what do they protect

It protects vital organs like the brain,heart and lungs

5

What does protection allow you to do in terms of performance and give an example

It’s allows you to perform well without the fear of injury. For e.g. skull protects the brain so you can header a ball or taking punches in boxing without injury

6

In movement, what can the muscles do

Muscles can move bones at joints

7

There are different types of movement at various joints what are they important for

They are important in different sports

8

Some bones contain what

Some bones contain bone marrow

9

Why are red blood cells important for exercise

Red blood cells are important for exercise because they transport oxygen that muscles need to move

10

Athletes with more red blood cells perform better why is that

They perform better because more oxygen can be delivered to their muscles

11

What do bones store

Bones store minerals like calcium and phosphorus

12

When bones store minerals what do they help

They help with bone strength- unlikely to break a bone

13

What are mineral storage needed for

They are also needed for muscle contraction so the body can move

14

What do long bones do

Long bones are strong and used by muscles to assist movement

15

Give an example of a long bones

Humerus in the arm

16

What do short bones support

Short bones support the weight of the body

17

Give an example of short bones

Tarsals in the foot

18

What are irregular bones suited for

They are suited for protection and muscle attachment

19

Give an example of a irregular bones

Vertebrae of the spine

20

What do flat bones do

Flat bones protect internal organs. Their broad surface allows muscle attachments

21

Name 5 flat bones

Cranium,sternum,ribs,scapula,pelvis

22

Name two short bones

Carpals and Tarsals

23

Name 4 long bones

Clavicle,humerus,phalanges and metatarsals

24

What is a joint

Joints is any points where 2 or more bones meet

25

What are the 8 joint movements

Flexion
Extension
Adduction
Abduction
Rotation
Circumdation
Plantar flexion
Dorsi flexion

26

What is flexion and give an example

Flexion is closing a joint example wrist movement during a basketball throw

27

What is extension and give an example

Extension is opening a joint example kicking a football

28

What is adduction and give an example

Adduction is moving towards an imaginary centre line example swinging a golf club

29

What is abduction and give an example

Abduction is moving away from the imaginary centre line example bringing back a tennis racket

30

What is rotation in p.e and give an example

Rotation is the clockwise and anti-clockwise movement example leg movement during a turnout in ballet

31

What is circumdation and give an example

Circumdation is the movement of a limb,hand or foot in a circular motion. Example bowling a cricket ball

32

What is plantar flexion and give an example

Plantar flexion is the extension at the ankle. Example would be pointing toes during gymnastics

33

What is dorsi flexion and give an example

Dorsi flexion is flexion at the ankle. Example would be lifting toes during gymnastics

34

What are the 4 joint type

Ball and socket
Pivot
Hinge
Condyloid
