How Muscles Produce Movement: Bones, Skin & Organs Explained

Muscles move bones, skin, and organs.

- Bones: Muscles are attached to bones by tendons. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone. This causes the bone to move.

- Skin: Muscles are also attached to skin by tendons. When a muscle contracts, it can cause the skin to move. This is how we are able to make facial expressions and move our limbs.

- Organs: Muscles can also move organs. For example, the muscles of the stomach and intestines help to move food through the digestive system.
