22
Q

principal mover for specific action; deltoid muscle in abduction of arm

A

agonist or primemover

23
Q

for opposite movement; latissimus dorsi and pectoralis

antagonist

24
Q

helps stabilize movement of one joint; inhibit undesirable movement

25
fixes the position of the limb when the movement is occurring; biceps and triceps, they hold the shoulder and elbow in position
fixator
26
bend a limb or one part of a limb against another
flexors
27
straighten a limb or one of its component parts
extensors
28
draw a part toward a median line or toward a neighboring part of limb
adductors
29
draw a part away from a median line or from a neighboring part or limb
abductors
30
turn or rotate a part downward on it's axis, palm of the hand
pronators
31
turn or rotate a part forward and upward on its axis
supinators
32
raise or lift a part as when the lower jaw in closing the mouth
elevators or levators
33
lower or depress a part as when the lower jaw in opening the mouth
depressors
34
draw part together or compress a space such as the pharynx and the abdomen
constrictors
35
widens an opening or a space
dilators
36
constrictors surrounding an opening such as mouth, pylorus and anus
sphincters
37
external connective tissue wrapping
epimysium
38
what the skeletal muscle is make out of
fascicles
39
bundles of individual muscle cells
muscle fibers
40
each fascicle is surrounded by connective tissue layer called the
perimsium
41
within the connective tissue, the third connective tissue layer which separates and electrically insulates the muscle fibers from each other
endomysium
42
each muscle fiber is subdivided by the scarcoplasmic reticulum into smaller cylinders called
myofibrils
43
composed of sarcomeres, attached end to end
myofibril
44
composed the thick myofilaments
myosin
45
compose of thin myofilaements
actin
46
subcomponents of thin myrofilaments
troponin, tropmyosin
47
muscle hemoglobin for transport of oxygen
myoglobin
