1 What do you know about skeletal system?
2 Elucidate the classification of bones?
3 what are is centre of gravity? How is it applied in sports and games?
4 Briefly discuss the principles of stability.
5 Elaborate the properties of muscles?
Answers
Explanation:
1.The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.
2.The bones of the body come in a variety of sizes and shapes. The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities.
3.Lowering the centre of gravity increases balance and stability in sport. This is why you can change direction faster by bending your legs and getting lower to the ground. It increases your stability, allowing you to adjust to greater force production by the legs.
4.Stability Principles and Balance in Sports. Stability principles give athletes rules about holding positions and staying on balance when running. ... An athlete's center of gravity is the exact middle of the body around which it can rotate freely in any direction and where the weight balanced on all opposite sides.
5.All muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten. ... Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.
please mark as brainliest answer ♥️ please thank my answer please friend ❣️✌️❤️ God bless you
