contains thick and thin filaments

Answer 19

myofibrils

Question 20

myofibrils thin filaments

Answer 20

-actin, troponin, tropomyosin

Question 21

relation of thin filaments

Answer 21

actin- myosin proteins
at rest, covered by tropomyosin
troponin hold tropomyosin

heads sticking out from bundle

Answer 23

myosin

Question 24

relation of thick and thin filaments

Answer 24

myosin heads are attracted to actin molecules

Answer 27

a band

Question 28

lighter, less dense are of sarcomere
contains remainder of thin filaments
z disc passes through

Answer 28

i band
