Muscles are attached to bones by tendons, which are tough bands of dense regular connective tissue. Tendons are woven into the coverings of both muscles and bones, and they are under extreme stress when muscles pull on them, so they are very strong. Muscles move by shortening their length, pulling on tendons, and moving bones closer to each other. One of the bones is pulled towards the other bone, which remains stationary.

What You'll Learn
Tendons attach muscles to bones
When a muscle contracts, it gets shorter and pulls on the bone it is attached to. When a muscle relaxes, it goes back to its normal size. Muscles can only pull and cannot push, so they have to work in pairs to move a joint. One muscle will contract and pull a joint one way, and another muscle will contract and pull it the other way.
Tendons are under extreme stress when muscles pull on them, so they are very strong and are woven into the coverings of both muscles and bones. The place on the stationary bone that is connected via tendons to the muscle is called the origin, and the place on the moving bone is called the insertion.

Muscles can only pull, not push
Muscles are attached to bones by tendons and help them to move. When a muscle contracts, it gets shorter and pulls on the bone it is attached to. Tendons are tough bands of dense regular connective tissue whose strong collagen fibres firmly attach muscles to bones.
Muscles can only pull and cannot push. They rely on the contraction of one muscle to create motion, while its opposing muscle must relax. This is a fundamental aspect of how movements are coordinated in the musculoskeletal system. Muscles work in pairs to create movement. For example, the bicep and tricep in your arm. When one muscle (like the bicep) contracts, it's pulling the forearm up. To straighten the arm, the bicep relaxes and the tricep contracts, pulling the forearm down. Muscles can't push because they can only contract, pulling on the bones to which they're attached.
The interplay of muscles, bones, and joints in humans and other vertebrates often involves forces acting in opposite directions. This is why muscles are attached at key points via ligaments and tendons, which can produce an overall pushing motion.

Muscles work in pairs to move a joint
Muscles are attached to bones by tendons, which are tough bands of dense regular connective tissue with strong collagen fibres. Tendons are woven into the coverings of both muscles and bones. Muscles move by shortening their length, pulling on tendons, and moving bones closer to each other.
Muscles can only pull and cannot push, so they have to work in pairs to move a joint. One muscle will contract and pull a joint one way, and another muscle will contract and pull it the other way. One of the bones remains relatively fixed or stable while the other end moves as a result of muscle contraction. The place on the stationary bone that is connected via tendons to the muscle is called the origin. The place on the moving bone that is connected to the muscle via tendons is called the insertion.

The place on the stationary bone connected to the muscle is called the origin
Muscles are attached to bones by tendons, which are tough bands of dense regular connective tissue with strong collagen fibres. Tendons are woven into the coverings of both muscles and bones. Muscles move by shortening their length, pulling on tendons, and moving bones closer to one another. One of the bones is pulled towards the other bone, which remains stationary. The place on the stationary bone that is connected via tendons to the muscle is called the origin. The place on the moving bone that is connected to the muscle via tendons is called the insertion.
The origin is the point at which the muscle is attached to the bone that remains relatively fixed or stable while the other end moves as a result of muscle contraction. The insertion is the point at which the muscle is attached to the bone that moves as a result of muscle contraction.
The tendon and aponeurosis form indirect attachments from muscles to the periosteum of bones or to the connective tissue of other muscles. Typically, a muscle spans a joint and is attached to bones by tendons at both ends.

The place on the moving bone connected to the muscle is called the insertion
Muscles are attached to bones by tendons, which are tough bands of dense regular connective tissue with strong collagen fibres. Tendons are woven into the coverings of both muscles and bones. When a muscle contracts, it shortens and pulls on the bone it is attached to. One bone remains relatively fixed or stable, while the other moves as a result of the muscle contraction. The place on the moving bone connected to the muscle is called the insertion. The insertion is connected to the muscle via tendons.
The insertion is one of two points at which a muscle is attached to bones. The other point is called the origin. The origin is the place on the stationary bone that is connected to the muscle via tendons. The muscle spans a joint and is attached to bones by tendons at both ends.
