Muscles are connected to bones by tendons, which are made of tough collagen fiber connective tissue. They are not to be confused with ligaments, which connect bones to bones, or fasciae, which connect muscles to muscles.
Muscles,tendons,and bones are related because tendons connect muscle to bone and ligaments connect bone to bone.Tendons connect your muscles to your skeleton so that your muscles will make the bones move to were you need it to go.
If you think about it, skeletal muscle are muscles that connect bones. So wherever you have bone, it is covered with skeletal muscle. Muscles do not connect bones. Muscles are the source for movement and protection for bones.
