Which functional group has the major responsibility for countering specific movement?
Which functional group has the major responsibility for countering a specific movement? The antagonist opposes the movement produced by the agonist. It is often responsible for returning a limb to its initial position.
Which type of muscle is responsible for producing a specific movement?
A muscle that has the major responsibility for producing a specific movement is a prime mover, or agonist, of that movement.
Which functional group produces the most force during a joint action?
Terms in this set (4) General function: Produces the most force during a particular joint action.
What is a muscle that provides the major force for producing a specific movement called a fixator an antagonist a synergist an agonist?
What is a muscle that provides the major force for producing a specific movement called? an agonist (prime mover)
What is the major factor controlling how levers work?
The arrangement of a muscle's fascicles determines its range of motion and power. Regardless of type, all levers follow the same basic principle: effort farther than load from fulcrum = mechanical advantage; effort nearer than load to fulcrum = mechanical disadvantage.
What is the muscle that provides the major force?
The prime mover, sometimes called the agonist, is the muscle that provides the primary force driving the action.
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.
What are muscle functional groups?
To describe how muscles work together, we can use the following four functional types: agonist, antagonist, synergist, and fixator.
What movement role is a muscle playing when it assists larger muscles during a particular motion?
The prime mover is helped by other muscles called synergists. These contract at the same time as the prime mover. They hold the body in position so that the prime mover can work smoothly. These muscles cause the movement to occur.
How do muscles create 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.
What is the main factor that determines the power of a muscle group of answer choices?
What is the main factor that determines the power of a muscle? The total number of muscle fibers available for contraction.
Which factor determines the classification of a lever?
The lever classes are identified by the relative location of the resistance, fulcrum and effort. First class levers have the fulcrum in the middle, between the load and resistance. Second class levers have resistance in the middle. Third class levers have the effort in the middle.
When describing the roles of muscles involved in a movement what is the role of the antagonist?
A muscle with the opposite action of the prime mover is called an antagonist. Antagonists play two important roles in muscle function: They maintain body or limb position, such as holding the arm out or standing erect.
When a group of skeletal muscles are responsible for a type of movement one muscle called Mover does most of the work but is helped by other muscles?
Most of the time, body movement is not produced by only one muscle but by a group of muscles. However, one muscle is responsible for most of the movement; this muscle is called the prime mover or agonist. Other muscels help the prime mover by stabilizing joints; these muscles are called synergists.
What is muscle function?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
How do muscles help in 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.
What are the main parts of the muscular system and their functions?
They are:
- Skeletal: As part of the musculoskeletal system, these muscles work with your bones, tendons and ligaments. Tendons attach skeletal muscles to bones all over your body. …
- Cardiac: These muscles line the heart walls. …
- Smooth: These muscles line the insides of organs such as the bladder, stomach and intestines.

What organ system produces movement?
The muscular system The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
How does the skeletal muscle produce movement?
Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.
What is the major function of muscle?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
What is the name of a muscle group that works with and assists the action of a prime mover?
The prime mover is helped by other muscles called synergists. These contract at the same time as the prime mover. They hold the body in position so that the prime mover can work smoothly. These muscles cause the movement to occur.
Which class of lever improves the speed of movement and the distance the load is moved more than it improves lifting the load?
3rd Reinforcement Exercises
| Lever Class | Advantage |
|---|---|
| 3rd | Range of Motion The load moves farther than the effort. (Short bicep contraction moves the hand far) |
| 2nd | Effort Required Smaller effort will move larger load. (One calf muscle can lift entire body weight) |
What are the components of a lever system describe the role of each component?
All lever systems are made up of four components: the load the fulcrum the effort the lever. The load is the object requiring moving, the effort is the muscular force we use to move the object, the fulcrum is the joint around which the movement occurs and the bones of the skeleton are the levers.
How do antagonistic muscles produce movement?
Antagonist muscles act as opposing muscles to agonists, usually contracting as a means of returning the limb to its original, resting position. During flexing of the forearm, the triceps brachii is the antagonist muscle, resisting the movement of the forearm up towards the shoulder.
How skeletal muscles produce movements?
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.
Which type of muscle is attached to the bones and helps produce body movement?
Skeletal muscle Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system).
Which property of muscle is responsible for movement of bones?
contraction and relaxation Solution : The property of contraction and relaxation of muscles is responsible for the movement of bones.
Which of these functions is a responsibility of the muscular system?
The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement.
Which two body systems are mostly responsible for movement?
The skeletal system works with the muscular system to help the body move.
How does the body create movement?
When you decide to move, the motor cortex sends an electrical signal through the spinal cord and peripheral nerves to the muscles, causing them to contract. The motor cortex on the right side of the brain controls the muscles on the left side of the body and vice versa.
