Muscle tissue

Question 1

A band

Answer 1

dark band

Question 2

I band

Answer 2

Light band

Question 3

Z disk

Answer 3

backbone of actin, divides sections of sarcomeres

Question 4

Endomysium

Answer 4

connective tissue that surrounds individual muscle fibers

Question 5

Perimysium

Answer 5

intermediate connective tissue that surrounds bundles of muscle fibers (fasciculi)

Question 6

fasciculi

Answer 6

bundles of individual muscle tissues

Question 7

Epimysium

Answer 7

connective tissue that surrounds a lot of bundles of fasciculi to make the muscle

Question 8

skeletal muscle longitudinal

Answer 8

you can see the nucleus squished on the sides of the muscle fibers. Very symmetrical, you can see the striations, kind of looks like potato sack cloth

Question 9

skeletal muscle cross section

Answer 9

looks like a bundle of fibers cut perpendicularly. You can see the endomysium and perimysium in between each fiber and bundle

Question 10

smooth muscle longitudinal

Answer 10

Looks like cartilage in that things kind of blend together. You can see the very oblong nucleus,

Question 11

smooth muscle cross section

Answer 11

Looks a bit like the cross section of skeletal muscle but less defined. You can see nucleus down the cross section

Question 12

cardiac muscle longitudinal

Answer 12

Looks striated but it is more squiggly than skeletal. The striations go more parallel than perpendicular

Question 13

cardiac muscle cross section

Answer 13

Defined bundles the the bundles are not square or uniform. Many irregularly shaped cylinders

Question 14

intercalated disks

Answer 14

Muscle fibers are shorter and the intercalated disks are where the fibers connect. Like z disks but for cardiac muscle

Question 15

striations

Answer 15

Where one section of the muscle meets up with the next one
