muscles, tendons (very basic terms), muscle groups (general action of main muscle groups) Flashcards
agonist
any muscle that produces certain effect
antagonist
muscle that actively opposes (the) movement (that is caused by agonist?)
synergists (2 POINTS)
- other muscles (not agonist/antagonist) that may modify action of agonist e.g. by eliminating unwanted side effect
- do NOT facilitate OR directly oppose movement
fixators
muscle employed to stabilise joint rather than employ movement
(tendons)
points of…origin
attachment to more proximal/central bone? (more stable bone?)
- WILL CHANGE DEPENDENT ON THE TYPE OF THE INDIVIDUAL MOVEMENT/DEPENDS ON THE SPECIFIC ACTION - like with agonists/antagonists??? *
(tendons)
points of…insertion
attachment to more distal/peripheral bone? (more moveable bone?)
- WILL CHANGE DEPENDENT ON THE TYPE OF THE INDIVIDUAL MOVEMENT/DEPENDS ON THE SPECIFIC ACTION - like with agonists/antagonists??? *
