Question 14

Name three types of muscles

Answer 14

There are 3 types of muscles, Cardiac (Heart), Skeletal (attaches to our bones), and smooth (digestive).

Question 15

What are Slow twitch fibres

Answer 15

Slow twitch fibres are used for muscular endurance – they contract slowly but do not fatigue (get tired) easily
Slow twitch fibres are typically red in colour due to the dense supply of capillaries
Slow twitch fibres are prevalent in endurance athletes, such as marathon runners

Question 16

What are Fast twitch fibres

Answer 16

Fast twitch fibres are used for muscular strength – they contract rapidly but fatigue easily
Fast twitch fibres are typically lighter in colour (white)
Fast twitch fibres are prevalent in strength athletes, such as sprinters

Question 17

What are the 4 functions of the Skeleton

Answer 17

1. Shape and Support
2. Movement
3. Protection
4. Blood Production

Question 18

What is protection in the skeleton

Answer 18

Internal organs are soft, delicate and easily damaged. These vital organs are protected by the skeleton. An example of this is the cranium protects the heart and the ribs help protect the heart and lungs.

Question 19

What is movement in the skeleton

Answer 19

Muscles are attached to the skeleton. Movement occurs when muscles contract and pull on bones making them move about joints. For example, the biceps muscle connects the shoulder and the elbow and helps with lifting.

Question 20

What is shape and support in the skeleton

Answer 20

The skeleton provides shape and support for the body. It forms the frame to which our muscles can attach and in which our organs can sit. An example is the backbone enables us to stay upright.

Question 21

What is blood production in the skeleton

Answer 21

The centre of some large bones contains red bone marrow, which creates red blood cells. The pelvis and femur are both important in blood production.

Question 22

What are all the Long bones in the body

Answer 22

Humerus, Ulna, Radius, Femur, Tibia, Fibula, Clavicle, Metacarpals, Phalanges, Metatarsals

Question 23

What are all the Short bones in the body

Answer 23

Carpals, Patella, Tarsals, Talus

Question 24

What is the purpose of Long bones

Answer 24

Allow a lot a of movement in the body as well as blood production

Question 25

What is the purpose of Short bones

Answer 25

Short bones are there for stability and small movements

Question 26

What are all the Irregular bones in the body

Answer 26

Vertebrate, Pelvis

Question 27

What is the purpose of Irregular bones

Answer 27

Irregular bones serve as protection for example several vertebrae protect the spinal cord also has a large surface area so muscles can attach

Question 28

What are all the flat bones in the body

Answer 28

Cranium, Scapula, Ribs

Question 29

What is the purpose of flat bones

Answer 29

Flat bones unlike irregular bones only provide protection for internal organs such as the cranium protecting the brain

Question 30

When a joint angle increase

Answer 30

Extension

Question 31

When a joint angle decreases

Answer 31

Flexion

Question 32

Pointing the toes downwards

Answer 32

Plantarflexion

Question 33

Lifting the toes upwards

Answer 33

Dorsiflexion

Question 34

Moving limbs away from the body centre

Answer 34

Abduction

Question 35

Moving limbs towards the body centre

Answer 35

Adduction

Question 36

Movement of a limb circular motion along a single axis

Answer 36

Rotation

Question 37

Limb tracing a cone shape

Answer 37

Circumduction

Question 38

Where a muscle joins a moving bone

Answer 38

Insertion

Question 39

Where muscles change length as they contract

Answer 39

Isotonic contraction

Question 40

Where a muscle joins a stationary bone

Answer 40

Origin

Question 41

Where the muscles contract but stays the same length

Answer 41

Isometric contraction

Question 42

The muscle that CONTRACTs to create movement

Answer 42

Agonist

Question 43

The muscle that RELAXES during movement

Answer 43

Antagonist

Question 44

Muscles that work in opposition. The create movement when one contracts and the other lengthens.

Answer 44

Antagonistic pair

Question 45

Muscle contraction but the muscle lengthens

Answer 45

Eccentric contraction

Question 46

What are the two different types of joints

Answer 46

Hinge joint
Ball and Socket joint

Question 47

What is ACL

Answer 47

The ACL is one of the most common ligaments to be injured. The ACL is often stretched or torn during a sudden twisting motion. This is when the feet stay planted one way, but the knees turn the other way.
