32
muscle tissue comparison is skeletal attached to muscle
true
33
is skeletal voluntary
true
34
does skeletal have single cells?
no. fused cells
35
does skeletal have gap junctions?
no.
36
do skeletal muscles have single nucleuses
no. multinucleated
37
protein related to skeletal muscle
troponin
38
neurotransmitter for skeletal
protein? acetylcholine (ACH)
39
proteins (3) for smooth muscle tissue
ACH norepinephrine oxytocin
40
proteins (2) for cardiac muscle tissue
ACH | norepinephrine
41
cardiac muscle tissue is voluntary
false
42
cardiac muscle is multinucleated. t/F
false
43
cardiac muscle tissue has multiple cells. t/f
false; has single cells
44
Cardiac muscle tissues are branched t/f
true
45
cardiac muscle tissues are not striated. t/f
false
46
is cardiac weak 2D?
no. strong 3D
47
smooth muscle tissues have intercalated discs t/f
false; cardiac tissue has the discs
48
protein found in cardiac tissue
troponin
49
smooth muscle tissues are voluntary t/f
false
50
smooth muscle tissue are single cells f/t
true
51
smooth muscle tissues have multiple directional fibers t/f
false; they have fewer random fibers
52
smooth muscles are striated t/f
false
53
smooth muscle tissue are weak 3D t/f
true
54
protein? for smooth m. tissue
colmodulin
55
what is colmodulin used for?
it's used by smooth muscle tissue to block myosin
56
two examples of multi-unit smooth muscle tissue
iris | sphincter
57
example of visceral muscle tissue
muscles of the GI tract
58
3 energy sources for muscular system
ATP creatine phosphate oxygen supply (long term)
59
four effects of fatigue
inability to contract muscle accumulation of lactic acid (pH) ACH supply exhausted (recycled? takes longer) decreased blood supply- low ATP- no contraction
60
four characteristics of a cramp
sustained involuntary contraction decreased blood supply- low oxygen- low ATP no ATP- no active transport- no Ca ++ out and no myosin detachment decrease in extracellular fluid electrolytes
61
what's usage of ATP for energy source
movement and detachment of myosin
62
how much reserve does ATP have as energy source
less than 6 sec.
63
is ATP as energy source recycled? (hmmm)
yes
64
what is a quick reserve for energy source for muscles
creatine phosphate
65
is creatine phosphate a more abundant reserve energy supply for muscles?
yes
66
two types of cellular respiration
glucose | glycogen
67
energy uses
for relaxation and contraction 25 % metabolic processes 75% heat
68
Oxygen supply is a long term supply t/f
true
69
what triggers the beginning of the process of muscles contracting (shortening)
happens when a protein called actin is pulled by a protein called myosin.
70
one example where smooth muscles are found
walls of arteries
71
3 areas where smooth muscles move materials thru the body
skin visceral organs internal passageways
