When you decide to move, the motor cortex sends an electrical signal through the spinal cord and peripheral nerves to the muscles, making them contract.The motor cortex on the right side of the brain controls the muscles on the left side of the body and vice versa.

Even when we sit perfectly still, muscles throughout the body are constantly moving.
Muscles help the heart beat, the chest rise and fall during breathing, and blood vessels regulate the pressure and flow of blood.
This process is under the control of local (e.g., growth factors and cytokines) and systemic (e.g., calcitonin and estrogens) factors that all together contribute for bone homeostasis.
An imbalance between bone resorption and formation can result in bone diseases including osteoporosis.
Bone contains three types of cells: Muscles pull on the joints, allowing us to move.
They also help the body do such things as chewing food and then moving it through the digestive system.
Cartilage (KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.
The bones of kids and young teens are smaller than those of adults and contain "growing zones" called growth plates.
When you run, the messages to the brain are more involved, because many muscles have to work in rhythm.
Muscles move body parts by contracting and then relaxing. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.
