13
Q

-non-striated, involuntary

-widely distributed in walls of hollow internal structures (airways, tracts, blood vessels)
-does not have striations
-style of contraction varies by the type of smooth muscle

A

smooth muscle

14
Q

plasma membrane

A

sarcolemma

15
Q

cytoplasm

A

sarcoplasm

16
Q

endoplasmic reticulum
pumps Ca

A

sarcoplasmic reticulum

17
Q

allows electrical signals or impulses
forms triads

18
Q

produces ATP

A

mitochondria

19
Q

contains thick and thin filaments

A

myofibrils

20
Q

myofibrils thin filaments

A

-actin, troponin, tropomyosin

21
Q

relation of thin filaments

A

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

22
myofibrils thick filament
myosin
23
shaped like golf clubs long shafts bundled to form thick filament heads sticking out from bundle
myosin
24
relation of thick and thin filaments
myosin heads are attracted to actin molecules
25
basic unit of myofibril
sarcomere
26
narrow, plate-shaped regions of dense material separate one sarcomere
z disc
27
dark, middle part of sarcomere extends length of thick and parts of thin filaments
a band
28
lighter, less dense are of sarcomere contains remainder of thin filaments z disc passes through
i band
29
narrow region in center of each a band contains thich filaments
h zone
30
region center in h zone proteins hold thick filaments
M line
