Flashcards in Topic 1.2.5 Deck (28):
1

What are the 3 functions of the skeleton?

Protection, Movement and Support

2

What are the 2 different synovial joints?

Hinge and Ball and Socket

3

What are the 2 different hinge joints?

Knee and Elbow

4

What are the 2 different ball and socket joints?

Shoulder and Hip

5

What are the 2 ranges of movement at a hinge joint?

Flexion and Extension

6

What are the 5 ranges of movement at a ball and socket joint?

Flexion, Extension, Adduction, Abduction and Rotation

7

What is extension?

The term given when the angle at the joint increases.

8

What is flexion?

The term given when the angle at the joint decreases.

9

What is abduction?

The movement of the limb away from the midline of the body.

10

What is adduction?

The movement of a limb towards the midline of the body.

11

What is rotation?

When the bone at a joint moves around its own axis.

12

What is weight bearing activity?

Activities that force your body to work against gravity. For example, walking, running and tennis.

13

What is the benefit of weight bearing activities?

Weight bearing activities increase bone density; this helps to reduce the risk of osteoporosis as a person gets older.

14

What are the 2 long term effects of exercise on the skeletal system?

Increased bone density and increased strength of ligaments and tendons.

15

What are the 3 benefits of increased bone density?

Reduce the chance of osteoporosis, gives better posture and reduces the chance of fractures.

16

What are the 2 benefits of stronger ligaments and tendons?

Better support of joints (more stability) and increased production of synovial fluid lubricates the joints aiding flexibility.

17

What are the 5 different potential injuries that might occur in the skeletal system?

Fractures, Tennis and Golfer's Elbow, Dislocation, Sprains and Torn Cartilage.

18

What are the 4 different types of fracture?

Compound, Closed, Simple and Stress

19

Which fracture is a broken bone that pierces the skin?

Compound

20

What is a closed fracture?

Broken bone but skin is not broken.

21

When the bone is only partially broken, what type of fracture is this?

Simple

22

What is a stress fracture?

Injury commonly caused through over-use. A small crack forms in the bone.

23

When a bone comes out of the joint it is known as what?

A dislocation

24

What is tennis / golfer's elbow?

Pain in a joint caused by overuse.

25

A damaged ligament is known as what?

Sprain

26

What injury may be caused through pivoting?

Torn cartilage

27

How would you treat a sprain?

Rest, Ice, Compression and Elevation (REST)

28

What are the 2 components of a balanced diet that are most important to the skeletal system?

Calcium and Vitamin D
