Q

all connective tissue extend beyond the muscle blank to form the blank

A

belly, tendon

28
Q

tendons may form thick flattened sheets, called blank

A

aponeuroses

29
Q

embryonic cells that fuse to form muscle fibers

30
Q

these are the reason that muscles are so long and multinucleated

31
Q

myoblasts that do not fuse become blank cells

A

myosatellite

32
Q

these muscle fiber cells assist in repair of damaged cells

A

myosatellite

33
Q

fiber cytoplasm of a muscle fiber

A

sarcoplasm

34
Q

plasma membrane of a muscle fiber

A

sarcolemma

35
Q

extensions of the sarcolemma into the sarcoplasm in muscle fibers

A

transverse tubule

36
Q

contractile organelles that extend the length of a muscle fiber

A

myofibrils

37
Q

myofibrils are surrounded by the blank

A

sarcoplasmic reticulum

38
Q

the functional unit of a myofibril is a blank

39
Q

sarcomeres are made of blank filaments and blank filaments

A

thick, thin

40
Q

thick filament that is twisted with globular heads, about 1.6 micrometers long, and there are 500 of them to one thick filament

41
Q

thin filaments are made of blank which is a structural protein and has coiled “beads”

42
Q

actin binds with blank because it has an active site

43
Q

two regulatory proteins of actin

A

tropomyosin, troponin

44
Q

the striated bands of filaments are blank

A

sarcomeres

45
Q

entire thick filament range

46
Q

only thin filaments

47
Q

only thick filaments

48
Q

both filaments are in this zone

A

zone of overlap

49
Q

divide and flank the sarcomere

A

sarcomere lines

50
Q

the end of the sarcomere made of actinin protein and anchor thin filaments

51
Q

middle of the sarcomere that stabilizes thick filaments and is a sarcomere line

52
Q

diagram a sarcomere

53
Q

structural protein that anchors a thick filament to a z line and accounts for elasticity and extensibility

54
Q

structural protein that holds F actin together on thin filaments

55
Q

structural protein that makes up the z line

56
Q

during contraction, myosin attaches to binding site of blank

57
Q

during contraction, atp causes the myosin to flex and pull on the blank

58
Q

the blank filaments slide inward during contraction

59
Q

neuron and all muscle cells are stimulated by the neuron in this

A

motor unit

60
Q

three things in neuromuscular junciton

A

motor unit, neuromuscular junction, synaptic terminal

61
Q

point of contact between the neuron and the muscle

A

neuromuscular junction

62
Q

end of axon that contacts motor end plate

A

synaptic terminal

63
Q

three more parts of the neuromuscular junction

A

motor end plate, synaptic cleft, neurotransmitter

64
Q

point on muscle fiber that contacts synaptic terminal

A

motor end plate

65
Q

chemical released into the gap in neuromuscular junction

A

neurotransmitter

66
Q

gap between motor end plates in neuromuscular junction

A

synaptic cleft

67
Q

neurotransmitter involved in neuromuscular junction

A

acetylcholine
