Study Notes
Muscle Types and Functions
- Antagonist: Muscle that opposes or reverses a particular movement, crucial for controlled motion.
- Agonist (Prime Mover): The primary muscle responsible for producing a specific movement, driving force during muscle contractions.
- Synergist: A muscle that assists the agonist in performing a movement, enhancing effectiveness and stability.
- Fixator: A type of synergist that immobilizes a bone or muscle's origin, allowing for more efficient movement of the agonist.
- Agonist: Referring to the muscle that contracts during an action, playing a vital role in movement execution.
- Antagonist: Referring to the muscle that relaxes to allow for the agonist's contraction and movement.
