400,000 feet low because when you see from the top you think it is more than a billion but not one scientist measured the grandcanyon.
When you bend your arm your brain send signals to your arm muscles telling the biceps, your upper arm muscles, to contract, go taut or stretch, while telling your triceps, lower arm muscles, to relax, become less tense or ease. Both of these muscles act as an antagonistic pair and work together to bend the arm. Each muscle uses the bones in your arm, the Humerus, the ulna and the radius, as an anchor.MonkeyLover-Dinda
The muscular and skeletal systems work together in the arm to bend. The muscles, attached to the bones by tendons, contract to move the bones at the joints and create the bending motion.
Muscles move body parts by contracting and then relaxing. Your muscles can pull bones, but they can't push them back to their original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
Muscles, bones and tendons work together to move your arm. The tendons will connect the muscles to the bones and the bones will provide the necessary support which will facilitate the movement.
Muscles change the relative position of the bones. The bones are just the passive (but required) part.
There are more than 600 muscles that move together to move your body! ---Bones form the structure for our body, while muscles are responsible for pulling the joints, allowing us to move. The cartilage, muscles, ligaments, and tendons, all working as one holding bones together and letting joints move. Muscles connect the joints to the bones. Flexing of the muscles and the ability to bend at the joints moves the bones to accomplish skilled body motions?
The bones do not move, neither do they work alone. In order to move the bones need help from the joints and muscles. The muscles pull on the joints therefore making the bones move.
The bones and muscles of the leg work together when the leg moves. The bones give the leg its structure, while the muscles hang onto the bones and allow the leg to actually move. The muscles make their movements via contractions and expansions.
Your muscles pull on bones but they never push bones.
Long bones.
Bones provide a framework for muscles to attach to and act as levers for movement. Muscles contract and pull on the bones, causing movement. Together, bones and muscles work in coordination to support movement and maintain the body's structure.
Arm muscles and ligaments work together to support and facilitate movement in the upper body by connecting bones and providing stability. Muscles contract to move the bones, while ligaments hold the bones together and help prevent excessive movement. This coordinated effort allows for smooth and controlled movement in the arms and upper body.
