|
|
|
A MUSCLE THAT ARE PRIMARILY RESPONSIBLE FOR MOVEMENT
|
PRIME MOVERS OR AGONIST
|
|
|
NAME 3 TYPES OF MUSCLES THAT PRODUCE MOVEMENT
|
1. AGONISTS OR PRIME MOVERS
2. SYNERGIST 3. FIXATORS OR FIXIATION MUSCLES |
|
|
ANOTHER NAME FOR AGONISTS
|
PRIME MOVERS
|
|
|
ANOTHER NAME FOR FIXATORS
|
FIXATION MUSCLES
|
|
|
A SPECIALIZED SYNERGISTS CALLES
|
FIXATOR
|
|
|
A MUSCLE THAT CAUSES MOVEMENT BUT IT( OPPOSES OR REVERSES A MMOVEMENT)
|
ANTAGONISTS
|
|
|
WHAT HAPPENS WHEN A PRIME MOVER OR AGONIST IS ACTIVE?
|
FIBERS OF THE ANTAGOINST ARE STRETCH AND IN THE RELAXED STATE
|
|
|
CAN AN ANTAGONIST ALSO REGULATE THE PRIME MOVER
|
YES BY PROVIDING RSISTENCE
( THIS RESISTENCE IS TO PREVENT OVERSHOOT OR TO STOP ITS ACTION) |
|
|
WHAT IS A PRIME MOVER OF ELBOW EXTENSION
|
THE BICEPTS MUSCLE OF THE ARM
|
|
|
PRIME MOVER OF ELBOW EXTENSION
|
ANATGONIZED BY THE TRICEPTS
|
|
|
A MUSCLE THAT ASSIST AN AGONIST IN ITS MOVEMENT
|
SYNERGISTS
|
|
|
WHAT IS THE ACTION OF A SYNERGISTS
|
IT AIDS IN THE ACTION OF AGONISTS BY REDUCING THE UNDESIRABLE OR UNNECCESSARY MOVEMENT
|
|
|
WHAT HAPPENS WHEN A CONTRACTION OF A MUSCLE CROSSES TWO OR MORE JOINTS
|
WOULD CAUSE MOVEMENT AT ALL JOINTS TO SPANNED IF THE SYNERGISTS WERE NOT THERE TO STABLIZE THEM
|
|
|
WHAT ALLOWS YOU TO MAKE A FIST WITHOUT BENDING YOUR WRIST?
|
BECAUSE THE SYNERGIST MUSCLES STABLIZE THE WRIST JOINT AND ALLOW THE PRIME MOVER OR AGONISTS TO EXERT ITS FORCE AT THE FINGER JOINTS
|
|
|
WATCH OUT BETWEEN THE WORDS AGONISTS AND ANTAGONSTS.
|
REMEMBER ANIT MEANS AGAINST
|
|
|
A MUSCLE THAT WORKS OR MOVES IN A DIRECTION OPPOSITE OF THE AGONIST OR IMPOSE OR REVERSE MOVEMENT
|
ANTAGONISTS
|
|
|
WHAT ARE THE 7 CRITERIA TO NAMING MUSCLES?
|
1. DIRECTION OF MUSCLE FIBERS
2. RELATIVE SIZE OF THE MUSCLE 3. LOCATION OF MUSCLE 4. NUMBER OF ORGINS 5. LOCATION OF THE MUSCLES ORGIN AND INSERTION 6. SHAPE OF THE MUSCLE 7. ACTION OF THE MUSCLE |
