Q

what are the parallel fibers and advantage

A

the advantage is movement. the fibers are strap, fusiform, triangular, and rhomboid

17
Q

Pectoralis Major
Rhomboid Major ( on posterior trunk)
which parallel fibers is this?

A

rhomboid

18
Q

what does unipennate mean and example?

A

one sided a muscle is unipennate is semimembranosus

19
Q

what is bipennate and example

A

both sided and example is rectus fermoris

20
Q

what does multipennate mean and name a muscle

A

multi sides such as the deltoid

21
Q

resting length meaning muscles

A

when a muscles is not shorted or lengthen

22
Q

define irritability in muscles

A

Ability to respond to stimuli
Response is to contract

22
Q

excursion how long can the muscles be shorted

A

Shortened to ~ ½ normal resting length

23
Q

excursion how long can the muscles be lengthen

A

Stretched to ~ twice as far as it can be shortened

24
Q

Active tension: what are the elements

A

contractile elements

25
Q

passive tension what are the elements

A

non contractile elements

26
Q

in order to be total tension what does it need to have

A

active + passive tension

27
Q

isokinetic exercises are such

A

specialized equipment leg extension

28
Q

define synergist

A

to assist muscle to do a particular motion

29
Q

define neutralizer

A

prevents unwanted motion

30
Q

define co contraction

A

agonist & antagonist contract at the same time

31
Q

define assisting mover

A

assists the agonist but is not as effective
