Muscular System

QuestionAnswer
types of muscle tissue skeletal, smooth, and cardiac
functions of tissue 1 create movement
functions of tissue 2 stabilize proteins
functions of tissue 3 circulation of fluids
functions of tissue 4 perform thermogenesis- body heat
4 properties of tissues irritability, contractility, extensibility, and elasticity
irritability able to respond to a stimulus, from nerve and external stimulus
contractility ability to contract and generate force
extensibility ability to stretch/lengthen
elasticity ability to go back to normal resting length
endo outside
peri in between
epi outside
sacromere muscle cell that shortens and lengthens actin and myosin
actin thin filaments
myosin thick filaments
muscle fiber types slow and fast twitch
slow twitch slow, back muscles
fast twitch quick, fatigue, leg muscles for sprinting
muscle attachments tendon, tenoperiosteal junction, and musculotendinous junction
tendon muscle to bone
tenoperiosteal junction tendon to bone
musculotendinous junction tendon to muscle
origin attachment closer to trunk
insertion attachment most distal
Sliding Filament Theory-1 stimulus to muscle, contracts muscle
Sliding Filament Theory-2 myosin heads, interact with actin, hooks
Sliding Filament Theory-3 myosin shortens towards m line
Sliding Filament Theory-4 z discs will come together to decrease H zone
Sliding Filament Theory-1 through 4 contraction
Sliding Filament Theory-5 signal stops
Sliding Filament Theory-6 myosin heads detach from actin
Sliding Filament Theory-7 goes back to normal state
Sliding Filament Theory-5 through 7 relaxation
parallel muscles produce range of motion
types of parallel muscles flat, strap, fusiform, convergent, and circular
flat muscles sheet like, latissiumus dorsi
strap muscles rectus abdominus
fusiform muscles biceps
convergent muscles deltoids/ pectoralis
circular muscles eyes/ mouth
oblique muscles produce more force
types of oblique muscles unipennate, bipennate, and multipennate
unipennate muscles wrist
bipennate muscles quadriceps
multipennate muscles deltoid

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.

To see how well you know the information, try the Quiz or Test activity.
