myosin filament slides into the blank band during the sliding filament theory in muscle contraction

A

a

27
Q

area between z lines area aka blank and can shorten and lengthen

A

sarcomere

28
Q

during muscle contraction, these bands shorten

A

i, h

during muscle contraction, this band does not change

A

a

30
Q

membrane that dips into the membrane of the skeletal muscle and is involved in action potentials

A

t tubules

31
Q

three types of cardiac muscle

A

contractile cells, pacemaker cells, conduction cells

32
Q

ventricles and atria have the blank type of muscle cells

A

contractile

33
Q

sa and av nodes have blank type of muscle cells

A

pacemaker

34
Q

bundle of his and purkinje fibers are this type of cardiac muscle

A

conduction

35
Q

contractile cells of heart are blank unlike other cells

A

striated

36
Q

heart only has this layer of muscle

A

endomyseum

37
Q

heart is filled with blank

A

capillaries

38
Q

cardiac muscle fibers blank unlike skeletal muscle

A

branch

39

the longitudinal longitudinal part of intercalated disc has blank junctions

A

gap

40
Q

transverse part of intercalated disk has blank junctions

A

tight adherent

41
Q

gap junction is aka blank

A

nexus

42
Q

at the z lines, where actin filaments bind to proteins of the membranes there is a large spot compared to zonula and macula adherens called blank

A

fascia adherens

43
Q

cardiac muscle does not have the ability to bring enough calcium about to make a contraction because it has an under developed blank compared to skeletal muscle

A

sarcoplasmic reticulum

44
Q

lack of calcium in heart leads to blank heartbeat

A

weak

45
Q

too much calcium in heart leads to blank heartbeat

A

fast irregular
