28
which types of MT have striations
skeletal and cardiac
29
which MT has intercalated discs
cardiac
30
what is the difference between an indirect and direct muscle attachment
indirect is muscle to tendon to bone
direct is just muscle to bone
31
what is the epimysium made of
dense irregular CT
32
what is perimysium made of
fibrous CT
33
what is endomysium made of
reticular CT
34
what does the epimysium cover
the body/entire muscle tissue
35
what does the perimysium cover
fascicle
36
what does the endomysium cover
the muscle fiber, superficial to the sarcolemma
37
what is the sarcolemma
muscle cell membrane
38
what are aponeuroses
fibrous extension of the epimysium resembling a sheet of connective tissue rather than a rope-like extension (sheet tendon)
39
what is an agonist
whole muscle providing the most force; prime mover
40
what is an antagonist
whole muscle providing the opposite movement of agonist
41
what is a synergist
whole muscles helping an agonist with movement
42
what is a fixator
whole muscle helps keep skeleton in place when performing movements; keep bone in place to avoid disarticulations
43
what is the origin of a muscle (o)
where muscle originates; more axial or fixed point of attachment
44
what is the insertion of a muscle (i)
where muscle inserts; more appendicular or moveable point of attachment
45
what is the action of a muscle (a)
joint movements; muscle action pulls insertion toward the origin
-muscle can only pull not push
46
what are the criteria used to name muscles
size
orientation of fibers
action
number of attachments
points of attachment
location
