21
Q

agonist (prime movers)

A

bring about an action

22
Q

antagonists

A

oppose agonists

23
Q

synergists

A

assist prime movers

24
Q

fixator

A

muscle that stabilizes the origin of agonist

25
Q

example of a movement parts with a bicep curl

A

agonist - bicep
antagonist - tricep
synergist -brachioradials
fixator - rotator cuff

26
Q

frontalis

A

big muscle on forehead
-emotions move it
-over frontal bone

27
Q

temporalis

A

covers temporal bone and temporal lobe
-tightening jaw

28
Q

orbicularis oculi

A

round muscle around the eye

29
Q

masseter

A

chewing and moving of jaw

30
Q

buccinator

A

cheek muscle
-outside cheek

31
Q

orbicularis oris

A

round muscle around mouth

32
Q

platysma

A

comes from jaw into neck

33
Q

sternocleidomastoid

A

helps with head turns and moving head downward
-from clavicle to sternum

34
Q

eye muscles ….

A

all work together in a way
-6 total

35
Q

superior rectus

A

elevates
-UP

36
Q

inferior rectus

A

depresses
-down

37
Q

medial rectus

A

adducts
-inward toward nose

38
Q

lateral rectus

A

abducts
-away from body

39
Q

superior oblique

A

intorsion
-SODA (superior oblique down and away)

40
Q

inferior oblique

A

extortion
-up and away

41
Q

cranial nerve and eye muscle

A

LR6 SO4 all the rest are 3

42
Q

motor unit

A

muscle cells innervated by one motor neuron
-excite and contract together

43
Q

endomysium

A

individual fibers wrapped

44
Q

perimysium

A

bundles of fibers are wrapped

45
Q

epimysium

A

bundles of bundles are wrapped

46
Q

fascia

A

muscle trunk covered by this

47
Q

tendons

A

attached to bones

48
Q

resting membrane potential

A

difference in electrical status of inside vs. outside of the cell

49
Q

chain reaction of ACh

A

motor neuron innervates muscles and the terminal bouton of
the axons dump neurotransmitter (acetylcholine) at the synapse; the Ach binds to
receptors on the muscle cell membrane and causes ion channels to open

50
Q

action potential

A

after a voltage threshold is reached, impulse is generated within muscles which signal for contraction
-must reach the potential to send down contraction

51
Q

what happens after a contraction

A

sodium potassium pump restores the resting membrane potential
-uses ATP energy
-Na out, K in
-Ca gets absorbed
