comparison of skeletal muscle to other muscle types

Question 1

appearance is very large long thin may extend to a foot or more

Answer 1

skeletal muscle or striated voluntary

Question 2

striations stripes due to visible actin and myosin filaments

Answer 2

skeletal muscle or striated voluntary

Question 3

control is conscious// voluntary

Answer 3

skeletal muscle striated voluntary

Question 4

slow twitch/slow oxidative fibers

Answer 4

aerobic

Question 5

thin fibers contract slowly

Answer 5

slow twitch slow oxidative fibers aerobic

Question 6

designed to contract for long periods resistant to fatigue

Answer 6

aerobic slow twitch slow oxidabitve fibers

Question 7

contain myoglobin give them a dark red color and and andvantege at aerobic metabolism

Answer 7

slow twitch slow oxidative fibers

Question 8

fast twitch fast glycolytic fibers

Answer 8

anaerobic

Question 9

thick fibers with powerful contractions contract quickly for speed

Answer 9

anaerobic or fast twitch fast glycolytic fibers

Question 10

lack myoglobin pale or whitish color

Answer 10

anaerobic no oxygen or fast twitch fast glycolytic fibers

Question 11

contract for short periods

Answer 11

anaerobic fast twitch fast glycolystic fibers

Question 12

intermediate fibers

Answer 12

fast twich fiber with the endurance of a slow twitch endurance training can cause fast twich to turn into intermediate

Question 13

cardiac muscle

Answer 13

striated involuntary

Question 14

appearance intermediate length thin branched

Answer 14

cardiac muscle /striated involuntary

Question 15

nuclei hundreds per cell

Answer 15

skeletal muscle

Question 16

nuclei one per cell

Answer 16

cardiac

Question 17

branched and connected via intercalated discs

Answer 17

cardiac

Question 18

pacemaker cells stimulate contraction

Answer 18

cardiac and visceral

Question 19

control is unconscious involuntary

Answer 19

cardiac muscle involuntary

Question 20

smooth muscle

Answer 20

nonstriated involuntary

Question 21

appearance small shorter spindle shaped cells

Answer 21

smooth muscle nonstriated involuntary

Question 22

lack striations stripes

Answer 22

smooth muscle nonstirated involuntary

Question 23

contractons in respose to hormones

Answer 23

hormones that effect blood flow or blood pressure smooth muscle

Question 24

histamine

Answer 24

causes vasodilation contractin by relaxing smooth muscle in arteries

Question 25

angiotensin

Answer 25

causes vasoconstriction make arteries small

Question 26

adrenalin

Answer 26

causes either vasodilation or vasoconstriction depending upon location in body

Question 27

hormone examples are gastrin or oxytocin

Answer 27

gastrin in stomach contraction help digestion

in oxytocin in uterus causes labor contractions

Question 28

two types of smooth muscle

Answer 28

multiunit and visceral unitary

Question 29

small bundles of cells that contract independently of each other

Answer 29

multiunit

Question 30

found in ciliary muscle and iris of eye in erector pilli of skin large air passageways

Answer 30

multiunit

Question 31

contractions initiated by nervous system

Answer 31

multiunit

Question 32

sheets of cells that contract simultaneously as one unit

Answer 32

visceral unitary

Question 33

uses pacemakers

Answer 33

visceral unitary and cardiac muscle

Question 34

forms wall of many organs digestive urinary reproductive tracts

Answer 34

visceral unitary
