Question 1

functions of the skeleton

Answer 1

Enables movement
blood production
protection of vital organs
provides shape and support

Question 2

how many bones do we have

Answer 2

206 bones

Question 3

Shapes and support:

Answer 3

Forms the frame to which our muscles can attach and our organs can sit on

Question 4

enables us to move

Answer 4

creation movements at the joints so when muscles contract they pull on the bone

protection of vital organs

Answer 5

protected by the skeleton

Question 6

Blood production

Answer 6

phalanges - long

Question 10

Function of long bones

Answer 10

Actors levers to produce large range of movement

Question 11

Function of short bones

Answer 11

Bones that enable movement and produce support

Question 12

Irregular bones function

Answer 12

Protection and support and their suits their specifically role

Question 13

Muscles

Answer 13

And a superstitious that has ability to contract producing movement in the body

Question 14

Muscles muscle types

Answer 14

back and neck trapezius
Deltoids are the shoulders
The pectorals the chest
Biceps upper arm
triceps upper arm
latissimus Dorsi - back
abdominals - abdomen
hip flexors - front of hip
gluteals - bottom
quadriceps - upper leg front
hamstrings - upper leg back
Gastrocnemius- lower leg back
tibialis anterior - sides of the lower leg

Question 15

trapezius

Answer 15

And rotate the shoulders with the head back and sideways example a swimmer turning their head to breathe ☺️🐳

Question 16

deltoids

Answer 16

Raises the arm forwards backwards and sideways example overhead clear in badminton

Question 17

pectorals

Answer 17

Move the arms in the words of the shoulder adduction example discussed through through

Question 18

biceps

Answer 18

Bend Oregon creating flexion of the example join back about

Question 19

triceps

Answer 19

Straightens the arm at the elbow extension example releasing a javelin or ball when throwing

Question 20

latissimus dorsi

Answer 20

Pause the arms down at the shoulder and draws it behind the back example front crawl

Question 21

abdominals

Answer 21

Creates a pool on the spine flexion creates a pole in the abdomen example a pike position in diving

Question 22

hip flexors

Answer 22

Are you sing to me or moving the leg forward at the hip flexion example striking a football

Question 23

gluteals

Answer 23

Post to look back at the hip extension racist like to the side abduction long jump take off

Question 24

hamstrings

Answer 24

bends the leg at the knee ex running stride

Question 25

gastrocnemius

Answer 25

Straight into the ankle joint plantarflexion example pointing your feet in gymnastics

Question 26

tibias anterior

Answer 26

Pause the toes upwards towards the shin Dorsey flexion to kick in football

Question 27

muscle fibres

Answer 27

This cells are a basic building blocks of the muscle electrical impulses from the brain causes it to contract in enabling movement

Question 28

fast twitch fibres

Answer 28

Larger size faster speed how do you force and low fatigue tolerance

Question 29

slow twitch fibres

Answer 29

Smaller their slower speed they produce less force and have a higher fatigue tolerance

Question 30

aerobic respiration

Answer 30

This oxygen to produce energy allows athletes to work at low to moderate intensity and for long periods of time

Question 31

anaerobic exercise

Answer 31

Short period of high intensity activities energy is provided rapidly and at least fatigue quickly and lactic acid is produced

Question 32

ex of anaerobic training

Answer 32

Strength and power based training such as weightlifting or high intensity interval training

Question 33

ex of aerobic training

Answer 33

Examples of aerobic training methods are continuous trainings such as running for 1 km

Question 34

antagonistic muscle action

Answer 34

Muscles are only able to pull on bones so can only create movement in One Direction therefore muscles come in pairs to enable movement into two directions example quadriceps and hamstrings

Question 35

agonist

Answer 35

the primer mover contracts to create movement

Question 36

antagonist

Answer 36

antagonist relaxes as the agnist muscle contracts to allow movement

Question 37

example what is the agonist and antagonist in the upward phase of a bicep curl

Answer 37

the biceps Is it is the agonist it contract creating flexion of the elbow the tricep relaxes allowing movement to occur so it is the antagonist

Question 38

antagonistic pair

Answer 38

Agonist and antagonist combined are known as a pair one contracts as the other relaxes

Question 39

isometric

Answer 39

Produces a force but stays the same length

Question 40

isotonic

Answer 40

Can change length as the contract

Question 41

eccentric isotonic

Answer 41

So lengthens wallet contracts lengthens

Question 42

concentric isotonic

Answer 42

Muscle shortens wallet contracts

Question 43

flexion

Answer 43

In a body part the angle of the joint decreases example performing a bicep curl curl curl

Question 44

extension

Answer 44

Straightening a body parts the angle and the joint increases example blocking a spike in the volleyball elbow
