dense connective tissue = collagen.

Question 41

what are cartilagenous joints connected by

Answer 41

entirely by cartilage

Question 42

movement in cartilagenous joints

what do synovial joints allow

Answer 43

movement

Question 44

what is there in the synovial bones

Answer 44

covered with a thin layer of strong, smooth articular cartilage.

Question 45

whats in the synovial joint

Answer 45

A very thin layer of slippery, viscous joint fluid separates and lubricates the two cartilage-covered bone surfaces.

Question 47

3 types of muscles

Answer 47

skeletal smooth cardiac

Question 48

function of muscle system

Answer 48

movement of the body, maintains posture, and circulates blood throughout the body

Question 49

what is the agonist muscle

Answer 49

main muscle moving in an exercise

Question 50

whats the anagonist muscle

Answer 50

opposing muscle to the Agonist

Question 51

how does agonist and anagonist mucles work

Answer 51

whilst one contracts the other relaxes

Question 52

how does the agonist and anagonis work tog

Answer 52

reciprocal inhibition

Question 53

reciprocal inhibition defenition

Answer 53

relaxation of muscles on one side of a joint to accommodate contraction on the other side.

Question 54

https://wordwall.net/resource/10847935/pe/antagonistic-muscle-pairs

Question 55

how to identify the agonist

Answer 55

contracted

Question 56

how to identify the anagonist

Answer 56

relaxes to allow agonist to contract

Question 57

what do skeletal muscles do

Answer 57

attach to bones and control movement of the limbs, head, neck, and body under conscious control

Question 58

how are skeletal muscles controlled

Answer 58

by neuromuscular signals from the brain

Question 59

where are smooth muscles / involunterary

Answer 59

These muscles line internal organs, blood vessels, and organs such found in the digestive and reproductive systems

Question 60

2 type of fibres in voluntary muscle

Answer 60

fast twitch and slow twitch fibres.

Question 61

fast twitch

Answer 61

ontract quickly, but do not use oxygen well and tire quickly.

Question 62

slow twitch

Answer 62

contract slowly, but use oxygen well and keep going for a long time

Question 63

what are there a lot of in muscle fibres

Answer 63

myofibrils

Question 64

what are myofibrils

Answer 64

cylinders of muscle proteins.

Question 65

what are the 2 things in myofibrils

Answer 65

actin and myosin filaments

Question 66

how are filaments arranged in myofibrils

Answer 66

hexagonal patterns

Question 67

theory of contracting a muscle

Answer 67

Sliding Filament Theory

Question 68

what is Sliding Filament Theory

Answer 68

During contraction, the thin filaments slide past the thick filaments, shortening the sarcomere

Question 69

actin filament

Answer 69

thin

Question 70

myosin filament

Answer 70

thick

Question 71

role of muscuoloskeletal system

Answer 71

provide form, stability and movement to the human body consists of bodys bones, muscle, tendons, ligaments, joints, cartillage

Question 72

role of interverteable disks

Answer 72

intervertebral disks act as shock absorbers keeping vertebrae seperated when theres impact from activity protects nerves that run down the middle of the spine and intervertebal discs

Question 73

what happens to thick and thin filaments during contraction

Answer 73

- each muscle fibre is made of smaller fibres called myofibrils - even smaller actin + myosin filaments - filamnets dlie in and out between each other to form a muscle contraction

Question 74

what is the bone marrow known as

Answer 74

is the ‘blood cell factory’

Question 75

what does bone marrow help us produce

Answer 75

- lymphocytes we need to fight infection, - erythrocytes cells we need to carry oxygen - thrombocytes we need to stop bleeding

Question 76

why do the filaments slide

Answer 76

shorten sacromere while filaments remain the same length
