100
Attachment to more stationary bone of action
What is the origin
100
Ability to shorten
What is contractibility
100
The primary muscle of the contration
What is the agonist
100
Involuntary contraction of a muscle
What is a spasm
100
1) away from midline 2) toward midline
What is 1) abduction 2) adduction
200
Attachment to more movable bone of action
What is the insertion
200
Ability to stretch
What is extensibility
200
The muscle that works against the primary muscle
What is the antagonist
200
Sustained contraction
What is tetanus
200
1) Pointing foot to floor 2) Pointing toes to ceiling

Dense, fibrous connective tissue that connects muscle to bone.
What is a tendon
300
Ability to return to resting position
What is elasticity
300
The muscle that helps the primary
What is the synergist
300
Contraction of muscle without changing length (ie. push against a wall)
What is isometric
300
1) Palms turned down 2) Palms turned up
What is 1) pronation 2) supination
400
Sheet of connective tissue (ex. what the abdominal muscles turn into)
What is an aponeurosis
400
Ability to respond to stimuli
What is excitability
400
Thin filaments of the motor unit (a part of the sliding filament mechanism)
What is actin
400
Contraction without change of length
What is isotonic

1) moving mandible forward 2) moving mandible backward
What is 1) protraction 2) retraction
500
Injury that involve the stretching or tearing of a musculo-tendinous (muscle and tendon) structure
What is a strain
500
Ability to transmit stimuli
What is conductivity
500
Thick filaments of a motor unit with heads for movement
What is myosin
500
2 Parts: 1) Muscle lengthens with contraction 2) Muscle shortens with contraction (origin & insertion of muscle move closer together against pressure)
What is 1) eccentric 2) concentric
500
1) soles of feet face each other (medially) 2) soles of feet face laterally
What is 1) inversion 2) eversion
