Antagonistic muscle pairs. That means to work in opposition to each other.One muscle produces movement in one direction and the other muscle produces movement in the opposite direction. It would seem to be contradictory but a very smooth movement occurs when they work this way.
All muscles.
By tensing.
origin
This is smooth muscle. It produces a wave of movement.
flexable
Muscle movement produces heat which will increase your body temperature.
The two concepts that explain how the body produces movement are muscle contraction and joint movement. Muscle contraction occurs when muscles shorten or lengthen in response to nerve signals, causing movement. Joint movement allows for the articulation of bones and the range of motion at joints to create different types of movement.
Agonist & AntagonistsAgonist is the muscle responsible for the primary movement ( muscle that contracts)Antagonist is the opposite muscle that must relax to allow the agonist to move a joint.
Antagonist: Controls movement, opposite of prime mover Prime Mover: Main muscle that is directly responsible for movement Synergist: Aids in movement of muscle
Muscle movement produces the most body heat.
None. Muscles only contracts. In order to extend, the muscle on the opposite movement has to contract. For example, the biceps help flex the elbow, but it does not extend the elbow; the triceps does that.
