contrasting three different types of muscle contractions
The muscle moves and changes length ex: lifting or lowering a weight
What is Isotonic
Joints allow bones to move relative to each each other other
What is movement
A muscle that assist the agonist in performing a movement
What is a synergist?
Immovable joint ex: sutures in skull
What is synarthrosis?
Synovial fluid is a vacuous egg-white-like fluid made mostly of water, hyaluronic acid and proteins
What is composition?
muscle tightens, but doesn’t move - stays the same length ex: holding a plank or push, pushing on a wall
What is isometric
joints hold the skeleton together and maintain posture
What is support/stability?
A muscle that stabilizes the origin of the agonist so it can work more effectively
What is a fixator?
slightly movable joints ex: pubic synthesis, or intervertebral discs
What is Amphiarthrosis?
Lubricates the articular surfaces to reduce friction
What is function 1?
muscle moves at same speed the whole time ex: rehab machines that control how fast you move
What is isokinetic?
joints permit a range of motion and cushion forces during movement
what is flexibility/shock absorption?
The fixed attachment point of a muscle (usually on the less movable joint)
What is a origin?
Freely movable joints (all synovial joints) ex: shoulder or knee joints
What is diarthrosis?
nourishes and delivers oxygen to the cartilage
What is function 2?
The muscle that opposes the action of The Agonist
What is the antagonist?
acts as a shock absorber during movement
What is function 3?
The main muscle responsible for producing a specific movement
What is The Agonist (prime mover)
removes the waist from the joint space
What is function 4?
