Answer 13

Arms and legs

Question 14

Where is smooth muscle found

Answer 14

lining of internal muscles

Question 15

Where is cardiac muscle found

Answer 15

Ventricle and atrium walls

Question 16

Describe role of skeletal muscle

Answer 16

Essential for movement and maintaining posture

Question 17

Which type of muscle do you have conscious control of

Answer 17

Skeletal

Question 18

Describe heart muscle

Answer 18

Does not become fatigued
Contracts rhythmically
MYOGENIC

Question 19

Define myogenic

Answer 19

Where electrical impulses in cardiac tissue do not require a stimulus

Question 20

Name two types of skeletal muscle

Answer 20

Slow twitch and fast twitch

Question 21

Describe slow twitch muscle

Answer 21

Used for endurance
Works for long periods of time
Contain many mitochondrion
High levels of myoglobin
Slow to fatigue and generate ATP

Question 22

Describe fast twitch muscle

Answer 22

Used for short bursts of energy
Quick and powerful contractions
Respire anaerobically

Question 23

Describe the relationship between phosphocreatine in muscles

Answer 23

Fast twitch fibres
Store large amount of phosphocreatine in the cytoplasm
Which provides a quick source of ATP during exercise

Question 24

Why does fast twitch muscle fatigue quickly

Answer 24

Lactate is produced as a by-product of anaerobic respiration
