Muscle Contraction
Muscle Contraction
Muscles can only contract, pulling on the bone they are attached to, they cannot actively push.
Agonist Muscle
Agonist Muscle
The primary muscle responsible for a specific movement. It contracts to produce the desired action.
Antagonist Muscle
Antagonist Muscle
The muscle that opposes the agonist's action. It relaxes to allow the agonist to contract.

Study Notes
Muscle Contraction Facts
- Muscle contraction involves the shortening and thickening of muscle fibers to produce movement.
- The agonist muscle is primarily responsible for creating movement by contracting.
- The antagonist muscle opposes the action of the agonist, facilitating smooth movement and control.
Muscle Attachment Points
- During contraction, the insertion point of a muscle moves toward the origin point, causing joint movement.
- Muscles typically have two attachment points: the origin (fixed end) and the insertion (moving end).
Joints and Bone Connections
- Joints are the points where two or more bones meet, allowing for movement and flexibility.
- The main function of joints is to provide support and enable different types of motion between bones.
