What is the function of the muscular system GCSE PE?
What is the function of the muscular system GCSE PE?
The muscular system works in conjunction with the skeleton to produce movement of the limbs and body. Ligaments and tendons are two main types of connective tissues that help the muscular-skeletal system produce movements.
What are the 3 types of muscle GCSE PE?
There are three types of muscle found in the human body:
- Skeletal Muscle.
- Smooth Muscle.
- Cardiac Muscle (heart muscle)
What is muscular system physical education?
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 cause movement GCSE PE?
Muscles cause movement by contracting across joints. Muscles are attached to the skeleton by tendons in two places: the insertion.
What does the antagonist do in PE?
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….Antagonistic muscle pairs.

How do muscles and bones work together to produce movement GCSE PE?
Only skeletal muscles work with bones and muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. When muscles contract, the pull or force, of muscle contraction is applied to levers, such as bones, resulting in movement of those levers.
What does muscular tissue do GCSE?
Muscle cells contain filaments of protein that slide over each other to cause muscle contraction. They contain many well-developed mitochondria to provide the energy for muscle contraction. In skeletal muscle, the cells merge so that the muscle fibres contract in unison.
How do muscles work GCSE?
Muscle types The body’s involuntary muscles work our internal organs. Voluntary muscles have fast twitch and slow twitch fibres. Fast twitch fibres contract quickly, but do not use oxygen well and tire quickly. Slow twitch fibres contract slowly, but use oxygen well and keep going for a long time.
What are 5 facts about the muscular system?
Five fun facts about the muscular system
- Muscles make up approximately 40 percent of total weight.
- The heart is the hardest-working muscle in the body.
- The gluteus maximus is the body’s largest muscle.
- The ear contains the smallest muscles in the body alongside the smallest bones.
What are the effects of exercise on muscular system in physical education?
Long term effects of exercise on the body systems
| Long term effects of exercise | |
|---|---|
| Muscular system | Muscle hypertrophy; increased strength of tendons; increased strength of ligaments |
| Skeletal system | Increase in bone density |
| Fitness | Increase in strength; increase in flexibility; increase in speed; increase in muscular endurance |
How does the muscular system work during exercise to 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 a fixator in PE?
Fixator. A muscle which acts as the stabilizer and helps the agonist work effectively of. one part of the body during movement of another part.
