Classifying Major Muscles

Are muscles that cause specific movements to
occur through its own contraction

for the effectiveness the prime mover
muscles are cross one or more structures
that can move.

Prime Movers:
Latissimus dorsi, Quadriceps, Pectorals
Hamstrings, Deltoids, Biceps and Triceps

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

A musle that works in concert with another
muscle to generate movement

stabilize muscle movents to keep them even and
control the movement so that it falls in a range of
motion

sometimes synergist form part of a fixator group

these muscles can work with agonist and prime movers which surround the joint which move in the opposite direction

common movements like turning the head and moving the toes synergist are required for movement

a muscle that relaxes while the other contracts

responsible for controlling motion, slowing it down, and returning limb to initial position

the biceps and triceps or antgonistic muscles

opposes the action of another muscle

primary role is to counter the motion
of prime movers

help the antagonist pair produce a more efficient movement

Are designed to "fix" and stabilize a joint

allows people to isolate movements to a
specific joint or are of the body with the
muscle group holding nearby joints in place

muscles that are made up of a ride range of contractile cells

fixator groups are at the ankles to keep joints stables so that ankles won't wobble and bend causing difficulties in balance
