Muscular System

Question 1

What are the muscular pairs?

Answer 1

agonist works as the antagonist relaxes.
Bicep and tricep
Hip flexors and gluteus maximum
Quadriceps and hamstrings
Tibialis anterior and gastrocnemius
Pectorals and rotator cuff
Abdominals and latissimus dorsi
Deltoid and trapezius

Question 2

What are the types of muscle contraction?

Answer 2

Isotonic- muscle changes length under contraction
>2 types: concentric; shortens under contraction
Eccentric; lengthens under contraction

Isometric- muscle stays the same under contraction

Question 3

What can and can’t muscles do?

Answer 3

The can pull not push

Question 4

What is the deltoid responsible for?

Answer 4

For abduction of the shoulder and Flexsion and extension

What does the rotator cuff supply?

Answer 5

Stability for the shoulder

Question 6

What are biceps responsible for?

Answer 6

Flexsion at the elbow

Question 7

What are triceps responsible for?

Answer 7

Extension at the elbow

Question 8

What does the abdominal aid?

Answer 8

Expiration

Question 9

What does the pectoral aid

Answer 9

Inspiration

Question 10

What do the hip flexors allow?

Answer 10

The leg to Flexsion and extension

Question 11

What do hamstrings cause?

Answer 11

Flexsion at the knee

Question 12

What does quadriceps allow?

Answer 12

Knee extension

Question 13

What does the gastrocnemius allow?

Answer 13

Plantar-flexsion at the ankle

Question 14

What does the tibialis anterior allow?

Answer 14

Dorsi-Flexsion

Question 15

What does the sterneidomastoid allow?

Answer 15

Inspiration

Question 16

What do tendons do?

Answer 16

Attach muscle to bone

Question 17

What do agonists do in antagonist pairs?

Answer 17

Produces the movement

Question 18

What does the antagonist do in antagonistic pairs?

Answer 18

Relaxes to allow the movement

Question 19

What do all muscles work in?

Answer 19

Pairs

Question 20

Examples of antagonistic pairs:

Answer 20

-Quadriceps and hamstrings
-bicep and triceps
-tibialis anterior and gastrocnemius
-hip flexors and gluteals

Question 21

Example of a bicep and triceps working together?

Answer 21

Downward faze of a press up bicep is the agonist and the tricep is the antagonist

Question 22

Example of the quadriceps and hamstrings working together?

Answer 22

Footballer kicking a football the hamstring contacts to flex the knee while the quadriceps relaxes to allow this

Question 23

Example of the gluteals and hip flexors working together?

Answer 23

Lie on your front and lift your leg up your gluteals with contract while your hip flexors relax to allow this

Question 24

What is a isotonic contraction?

Answer 24

A muscle contraction that results in movement e.g push up or running

Question 25

What is a isometric contraction?

Answer 25

Muscle contracts but no movement occurs e.g plank or wall sit

Question 26

What is concentric?

Answer 26

When the muscle contracts and shortens e.g bicep during upward phase of a curl

Question 27

What is eccentric?

Answer 27

When the muscle contracts and lengthens e.g bicep during downward phase of a curl
