What is it called when two muscles work together to produce movement?
Muscles that work like this are called antagonistic pairs. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

How do muscles produce movement?
Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
When two muscles work together to produce movement the muscle that opens a joint is called the extensor True or false?
The muscle that contracts to cause a joint to bend is called the flexor. The muscle that contracts to cause the joint to straighten is called the extensor. When one muscle is contracted, the other muscle from the pair is always elongated.
What is a fixator muscle anatomy?
Definition. noun, plural: fixator muscles. (anatomy) A muscle that serves as a stabilizer of one part of the body during movement of another part.
How muscles work together?
How muscles and bones work together?
The muscles of the muscular system keep bones in place; they assist with movement by contracting and pulling on the bones. To allow motion, different bones are connected by joints which are connected to other bones and muscle fibers via connective tissues such as tendons and ligaments.
How do muscles work together to produce movement?
It is a twitch muscle only and contracts involuntary each time the heart beats. In order to move, muscles work in pairs known as synergist, agonist and antagonist muscles. Agonist muscles are typically associated with the movement itself and contract while another muscle relaxes.
Which is the joint that produces the most movement?
The degree and type of movement that can be produced at a synovial joint is determined by its structural type. While the ball-and-socket joint gives the greatest range of movement at an individual joint, in other regions of the body, several joints may work together to produce a particular movement.
What kind of movement can a synovial joint produce?
The type of movement that can be produced at a synovial joint is determined by its structural type. While the ball-and-socket joint gives the greatest range of movement at an individual joint, in other regions of the body, several joints may work together to produce a particular movement.
What kind of muscles are in the human body?
There are three unique kinds of muscles in the human body: skeletal muscle, smooth muscle and cardiac muscle. Skeletal muscles operate in pairs and can be contracted voluntarily through exercise or movement.
