Explanation:
Detailed explanation-1: -A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.
Detailed explanation-2: -Immovable – the two or more bones are in close contact, but no movement can occur – for example, the bones of the skull. The joints of the skull are called sutures. Slightly movable – two or more bones are held together so tightly that only limited movement is permitted – for example, the vertebrae of the spine.
