1When stronger muscle contraction is needed, ___________ occurs.
- Arecruitment
- Bsynergistic reinforcement
- Csummation
- Disometric contraction
2A motor unit is a [blank_start]neuron[blank_end] and all the [blank_start]myotubes[blank_end] it stimulates.
- Aneuron
- Bmyotubes
3Bigger motor units are for more precise movements.
- ATrue
- BFalse
4What type of muscle contraction is when the muscle, without either shortening or lengthening, maintains the contraction.
- Aisometric
- Bisotonic
- Cconcentric
- Deccentric
5Which muscle contraction shortens as time progresses?
- Aisometric
- Bisotonic
- Ceccentric
- Dconcentric
6What type of muscle contraction is when the muscle actively lengthens during contraction
- Aisometric
- Bisotonic
- Ceccentric
- Dconcentric
7What type of muscle contraction begins shortening as the tension increases?
- Aisometric
- Bisotonic
- Cconcentric
- Deccentric
8What influences muscle shape?
- ABone shape
- BHow much power required
- CWhat type of movement needed
- DType of joint action
- EType of fiber structure
- FHow far the muscle is from the site of action
- GMuscle innervation routes
- HHow much myoglobin is there
9[blank_start]Longer[blank_end] the muscle the [blank_start]more[blank_end] finetuned the movement is.
- Amore
- BLonger
10The [blank_start]number[blank_end] of muscle fibers determines the amount of [blank_start]power[blank_end] needed. The [blank_start]length[blank_end] of muscle fibers determines the degree of [blank_start]contraction[blank_end] needed.
- Apower
- Blength
- Cnumber
- Dcontraction
11What types of muscles are these?
- Aconvergent
- Bfusiform
- Cparallel
- Dunipennate
- Ebipennate
- Fmultipennate
- Gcircular
12Muscles usually work in pairs
- ATrue
- BFalse
13[blank_start]Agonist[blank_end] muscle is the prime mover, or the main mover.
[blank_start]Antagonist[blank_end] muscle is the opposer.
[blank_start]Synergist[blank_end] muscle helps the agonist muscle by reinforcing the same movements. An example is the [blank_start]brachioradialis[blank_end] for biceps brachii.
If the synergist helps [blank_start]stabilize[blank_end] the movement, it is called a [blank_start]fixator[blank_end].- AAgonist
- BAntagonist
- CSynergist
- Dbrachioradialis
- Efixator
- Fstabilize
14There are two types of fixators.
An [blank_start]essential[blank_end] fixator is one that clamps up at [blank_start]proximal[blank_end] joints to allow movement at the [blank_start]distal[blank_end] joints.
A [blank_start]postural[blank_end] fixator is the one that helps maintain the body's [blank_start]posture[blank_end] even if the center of [blank_start]gravity[blank_end] changes due to position.- Aessential
- Bpostural
- Cproximal
- Ddistal
- Eposture
- Fgravity
15Skeletal muscle, which moves bones, makes up the majority of our musclular body mass.
- ATrue
- BFalse
