Muscles move your bones, therefor making locomotion possible.
permit movements and transfer a load between bones
In the body, joints act as the fulcrum when bones function as levers. Joints provide a pivot point around which bones can move to generate mechanical advantage for various movements.
Muscles that are attached to the bone and allow body movements are Skeletal Muscles.
Muscles contract and relax to move bones at joints. This coordinated action allows for smooth and precise movements. The muscles provide the force needed to move the bones, and the bones provide a framework for muscles to exert their force.
for our bones to be strong to be physically fit
Assuming that was even possible, it would be limp and have no function because there would be no bones inside to provide structure.
They get older and weaker that makes them more sick that could cause them to die as soon as possible
Gliding movements involve one bone moving smoothly over another within a plane, while angular movements increase or decrease the angle between two bones. Circular movements involve bones moving in a way that describes a cone, and special movements include unique movements like opposition of the thumb.
An orthopedic physician is a doctor that specializes in bones. Physical therapists also have some focus on bones as well as the muscles and movements.
In order to move, muscles pull on the joints to pull the bones and let them move.
