Classifying Major muscles based on functions

The human body relies on various muscle groups to facilitate movement, each playing distinct roles. Fixators stabilize joints to ensure balance, preventing unwanted movements and aiding in efficient movement by securing surrounding joints.

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.
