1these are bundles of muscle fibers
fascicles
2does the arrangement of fascicles determine the power and range of motion?
yes
3the longer the fibers = _______ ROM, ______ power
greater, less
4the more fibers per cross section = ________ power, ______ ROM
greater, less
5what are the types of fascicle arrangements
parallel, fusiform, circular, triangular, pennate
6type of fascicle arrangement that runs parallel to the muscles long axis and has fewer fascicle, long fibers
parallel
7a type of fascicle arrangement that is nearly parallel, but muscle tapers at the both ends
fusiform
8the fibers of a fusiform muscle is _____ on the belly, _____ near the tendons
longer; taper
9the ROM of a fusiform muscle is _______ than power, but stronger than pure parallel
greater
10a type of fascicle arrangemnet that ia arranged concentrically around an opening
circular
11this are also known as sphincters
circular
12what is the arrangement of a circular muscle?
concentrically or circular
13a type of fascicle arrangement that the broad area of a fascicle converges at a single tendon and it allows versatile direction of pull
triangular
14a type of fascicle arrangement that its short fascicles are attached obliquely to the tendon
pennate
15what are the types of pennate muscle
unipennate, bipennate, multipennate
16this is the main muscle that causes the movement (prime mover)
- agonist
- antagonist
- synergist
- fixators
17this opposes the action of the prime mover, it either relaxes or stretches
- agonist
- antagonist
- synergist
- fixators
18this is the muscle that assist the agonist muscle
- agonist
- antagonist
- synergist
- fixators
19what are the fx of a synergist muscle?
stablizes intermediate joints; prevents unwanted movements
20the muscle that stablizes the origin of the agonist muscle and it allows the muscle to act more efficiently
- agonist
- atagonist
- synergist
- fixators
