Question 1

Answer 1

smooth- involuntary control from autonomic nervous system
cardiac- autonomous contraction but influence of ANS and circulating chemical
skeletal-voluntaty control attached to bones to bring about movement on contraction

Question 2

skeletal muscles structure

Answer 2

myofilaments -> myofibril -> myofibre -> fascicles ->muscle -> tendon -> bone

Question 3

macroscopic structure of muscles

Answer 3

epimysium -> perimysium -> endomysium

aka compartmentalisation

Question 4

Answer 4

myoglobin and mitochondria

Question 5

Answer 5
