Classifying Major Muscles
Fixators
fixator groups are at the ankles to keep joints stables so that ankles won't wobble and bend causing difficulties in balance
muscles that are made up of a ride range of contractile cells
allows people to isolate movements to a
specific joint or are of the body with the
muscle group holding nearby joints in place
Are designed to "fix" and stabilize a joint
help the antagonist pair produce a more efficient movement
Antagonist
primary role is to counter the motion
of prime movers
opposes the action of another muscle
the biceps and triceps or antgonistic muscles
responsible for controlling motion, slowing it down, and returning limb to initial position
a muscle that relaxes while the other contracts
Synergist
common movements like turning the head and moving the toes synergist are required for movement
these muscles can work with agonist and prime movers which surround the joint which move in the opposite direction
sometimes synergist form part of a fixator group
stabilize muscle movents to keep them even and
control the movement so that it falls in a range of
motion
A musle that works in concert with another
muscle to generate movement
Prime Movers
the muscle that has the most influence in
one direction on the joint it acts on
the prime mover in extension of
the forearm is the triceps
Are muscles that cause specific movements to
occur through its own contraction
Prime Movers:
Latissimus dorsi, Quadriceps, Pectorals
Hamstrings, Deltoids, Biceps and Triceps
for the effectiveness the prime mover
muscles are cross one or more structures
that can move.
