Musculoskeletal system

Question 1

What’s the function of the flat bones?

Answer 1

To protect vital organs

Question 2

What is a joint?

Answer 2

When two or more bones meet for the purpose of moving a body part

Question 3

What is a synovial joint?

Answer 3

The most common type of joint in the body, the joint cavity contains synovial fluid

Question 4

Function of the synovial membrane

Answer 4

Produces synovial fluid

Question 5

Function of synovial fluid

Answer 5

Lubricates the joint to reduce friction

Question 6

Function of the joint capsule

Answer 6

It holds everything in place

Question 7

Function of the bursae

Answer 7

It sits between tendon and bone to prevent friction

Question 8

Function of cartilage

Answer 8

It covers the end of the bone providing a smooth friction free surface, shock absorber

Question 9

Function of the ligaments

Answer 9

Joins bone to bone

Question 10

Function of the tendons

Answer 10

Joins muscle to bone

Question 11

Flexion

Answer 11

Bending the limbs at a joint

Question 12

Extension

Answer 12

Straightening the limbs at a joint

Question 13

Abduction

Answer 13

Moving the limbs away from the midline of your body

Question 14

Adduction

Answer 14

Moving the limbs towards the midline of your body

Question 15

Rotation

Answer 15

A circular motion around a fixed point

Question 16

Plantar flexion

Answer 16

When the foot flexes downwards

Question 17

Dorsi flexion

Answer 17

The upwards flexion of the foot

Question 18

Agonistic

Answer 18

The muscle which is contracting in an antagonistic muscle pair

Question 19

Antagonistic

Answer 19

The muscle which is relaxing in an antagonistic muscle pair

Question 20

Isotonic

Answer 20

A contraction where movement does take place, the muscle changes length

Question 21

Isometric

Answer 21

A contraction where there is no visible movement, the muscle stays the same length

Question 22

Prime mover

Answer 22

The main muscle which contracts

Question 23

6 functions of the skeleton

Answer 23

1. Production of blood cells
2. Support for muscles and organs
3. Shape such as height and build of our bodies
4. Mineral storage such as calcium and phosphorus which can be released into the blood
5. Movement- anchor for muscles to pull against
6. Protection for vital organs

Question 24

Ball and socket joint

Answer 24

• Rotation
  -Flexion and extension
  -Abduction and adduction

Question 25

Hinge joint

Answer 25

-Flexion and extension

Question 26

Antagonistic pair

Answer 26

As one muscle contracts (agonist) the other relaxes (antagonist)

Question 27

Eccentric contraction

Answer 27

When the muscle lengthens under tension

Question 28

Concentric contraction

Answer 28

When the muscles shortens under tension

Question 29

What is the structure of the skeletal system?

Answer 29

1. Movement happens at joints
2. The shape and type of bones allow for different movements.
3. Flat bones protect vital organs.
4. Different joints allow different types of movement.
5. Bones provide an attachment point for muscles.
