QuestionAnswer
describe the size of muscle fibres larger than other cells and can be length of entire muscle
name structures of muscle fibre sacrolemma transverse (T) tubules sacroplasmic recticulum myofibrils sacromeres
muscle fibre plasma membrane? sacrolemma
sacrolemma? muscle fibre plasma membrane
what does the sacrolemma surround? sacroplasm
sacrolemma is studded with? T tubules
T tubules connect what? sacrolemma to contractile parts of cell
T tubules contain what? extracellular fluid
T tubules are important for what? coordinated contraction of entire cell
what are myofibrils made of? contractile myofilaments of actin and myosin
what are myofibrils surrounded by T tubules and sacroplasmic recticulum
what do myofibrils connect to sacrolemma at both ends of muscle fibre so contraction shortens whole cell
where do glycogen granules and mitochondria sit? sacroplasm adjacent to myofibrils to provide ATP for contraction
why do glycogen granules and mitochondria sit in the sacroplasm adjacent to myofibrils to provide ATP for contraction
what sits in the sacroplasm adjacent to myofibrils to provide ATP for contraction mitochondria and glycogen grandules
TC? terminal cisternae
TC contain high conc of? Ca2+
why is a high conc of Ca2+ needed in TC? for contraction
triad? 2x TCs and a T tubule
2x TCs and T tubule? triad
sacroplasmic recticulum is important why? Ca2+ prevented from being pumped out the cell?
sacromeres? repeating unit of myofibrils
alternating patterns of light and dark are created by what in sacromeres? density differences
alternating patters of what are creates by density differences in sacromeres? light and dark

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
