Flashcards in The Muscular System Deck (27):
1

There are two different types of muscles what are they

Voluntary and involuntary

2

What do voluntary muscles do

They are under your control and help the body move

3

Give an example of a involuntary muscle

Cardiac muscle which forms the heart

4

When exercising, what do voluntary muscles need

They need oxygen to move the body

5

The heart pumps blood and carries what and where to

Carries oxygen to the muscles

6

What the function of the biceps and give an example

Flexion at the elbow e.g. curling weights

7

What is the function of the triceps and give an example

Extension at the elbow e.g jump shot in netball

8

What is the function of the hamstrings and give an example

Flexion at the knee e.g bringing your foot back to kick a football

9

What is the function of the quadriceps

Extension at the knee e.g. performing a drop kick in rugby

10

What is the function of the pectorals major

Adduction and flexion of the shoulder e.g a forehand hit in tennis

11

What is the function of the gastrocnemius and give an example

Plantar flexion at the ankle e.g standing on your toes in ballet

12

What is the function of the hip flexors and give an example

Flexion of the leg at the hip e.g. lifting your knee when sprinting in running

13

What is the function of the deltoid and give an example

Flexion,extension,abduction or circumdation of the shoulder for e.g doing a front crawl in swing

14

What is the function of the tibalis anterior and give an example

Dorsi flexion at the ankle e.g. a heel side turn in snowboarding

15

What is the function of the latissimus dorsi and give an example

Extension,adduction or rotation at the shoulder e.g. during a butterfly stroke in swimming

16

What are antagonist muscles

Antagonistic muscles are pair of muscles that work against each other

17

What is the agonist

The agonist is the muscle that is contracting to produce movement

18

What is the antagonist

The antagonist is the muscle that is relaxing

19

When the knee-hamstrings & quadriceps shows flexion which is the agonist and the antagonist

Agonist-hamstrings
Antagonist- Quadriceps

20

When the knee-hamstrings & quadriceps shows extension which is the agonist and the antagonist

Agonist- quadriceps
Antagonist-hamstrings

21

In the elbow there’s the biceps and triceps when is shows flexion which one is the agonist and which is the antagonist

Agonist-Biceps
Antagonist-Triceps

22

In the elbow there’s the biceps and triceps when it shows to be extensions which one is the agonist and which is the antagonist

Agonist-Triceps
Antagonist-Biceps

23

All muscles are made of up of what

All muscles are made up of fibres

24

The muscle fibres can be what

Muscle fibres can be slow twitch or fast twitch

25

What is the slow twitch type 1 used for

Suited for low intensity work e.g. marathon running as they can be used for a long period of time without getting tired

26

What is fast twitch type IIA used for

Type IIA is used in anaerobic work, can be improved through continuous training

27

What is the fast twitch type IIX

Type IIX is used in anaerobic work. Useful in short bursts of exercise e.g. 100m sprint
